A P-2000/C-2000/RT-2000 Operators Manual Introduction The Wulfsberg "2000" family of Flexcomm products are comprised of the P-2000 panel mount transceiver and the RT-2000 remote mount transceiver which is controlled by the C-2000 control head. The P-2000 and RT-2000 are capable of being populated with one or two ITM's (Internal Transceiver Modules) covering any combination of the following frequency bands: VHF 136-174 MHz, UHF -1 (403-470 MHz), UHF -2 (450-520 MHz) and UHF800

(806-870 MHz). For applications where multiple points of user operation are required, one or more C-2000's can be added. For purposes of this manual the term "P-2000" shall be used to describe a P-2000 or C-2000/RT-2000 installation. In both systems, the features and user interface is identical. Features The P-2000 provides a host of powerful features, including:

Multi-band operations: One or Two ITM's covering any combination of the following frequency bands:

136 - 174 MHz (10/1 Watt Transmit Power) 403 - 470 MHz (10/1 Watt Transmit Power) 450 - 520 MHz (10/1 Watt Transmit Power) 806 - 870 MHz (3/1 Watt Transmit Power) Clear and bright Color LCD display showing Active/Standby channel selection along with other critical operational information. 255 Preset channel memory in each internal transceiver module. The powerful yet incredibly simple user interface that allows the user to select channels using the firm tactile feedback keypad or rotary knobs. Modulation types available in the P-2000 include FM analog, P25 Digital conventional, P25 Trunking and Motorola 3600 Baud Trunking. Transceivers are capable of operating on 12.5 kHz, 20.0 kHz, and 25.0 kHz channels depending on options. Multiple types of encryption are available as options (AES, DES, DES-XL, DES-OFB, DVP and DVI). In addition, MDC1200 OTAR and P25 OTAR are standard in all models that include encryption capability. One or Two microphone/headset interfaces are supported. This provides retrofit applications the ability to use both transceivers even if only one microphone/headset port is available on the aircraft audio panel system. If two microphone/headset ports are used, the P-2000 is capable of independent operation of each ITM. In other words, one user can be operating on FM1 while the other user independently uses FM2. Advanced multi-radio modes, such as Relay, Simulcast and Relay-Simulcast. Programming port on the front of the panel allows for computer loading of channel information and encryption key loading. Page 4 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev. A Wulfsberg's exclusive QMEM (Quick Memory) function allows for fast access to preset memory channels. P-2000/C-2000/RT-2000 Operators Manual Transceiver Overview The Wulfsberg 2000 family of radio products are FM Tactical transceivers that incorporates one or two transceiver modules and control functions into a single panel mount unit (P-2000) or a panel mount control head (C-2000) and remote mount RT-2000 Transceiver. Part number variations of the unit exist for any combination of the following frequency bands: 138-174 MHz, 403-470 MHz, 450-520 MHz, and 806-870 MHz. Each transceiver module with the exception of the 806-870 MHz band can transmit with 1 or 10 Watts transmit power. The 800 MHz unit produces 1 and 3 watts transmit power. The P-2000 can operate by itself or in conjunction with the C-2000 control display acting as a remote slave control. Input voltage is 28 volts DC and the keypad is backlit from either 28VDC, 5 VDC or 5 VRMS AC. The Wulfsberg C-2000 is a control display unit that can be used as a slave control head with a P-2000 panel mount transceiver, or as a primary or slave control head for the RT- 2000 remote transceiver. Versions of the C-2000 include black faceplate and options for either Standard or NVG compatible displays. Input voltage is 28 volts DC and the keypad is backlit from either 28 VDC, 5 VDC or 5 VRMS. The Wulfsberg RT-2000 is a remote mounted transceiver that incorporates one or two transceiver modules in a remote mounted unit. It must be controlled by at least one C-2000 control head. Additional C-2000's can be added to the system for multi-positional control of the transceiver. Part number variations of the unit exist for any combination of the following frequency bands: 138-174 MHz, 403-470 MHz, 450-520 MHz, and 806-870 MHz. Each transceiver module with the exception of the 806-870 MHz band can transmit with 1 or 10 Watts transmit power. The 800 MHz unit produces 1 and 3 watts transmit power. Operationally a P-2000 or C-2000/RT-2000 system operates identically with the exception of the PC/Keyloading interface. For a P-2000 the interface is located on the front of the P-2000. In a C-2000/RT-2000 system, the connector on the RT-2000 is used for PC/Keyloading functions. The connector on the C-2000 is not currently used. For the purposes of this operators manual the use of the phrase P-2000 will be used to cover both P-2000 and C-

2000/RT-2000 systems. Page 5 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev.

A P-2000/C-2000/RT-2000 Operators Manual The Home Page The HOME PAGE is the primary operational page of the P-2000. The HOME PAGE becomes visible when the P-

2000 is ready for user input, immediately after the power up and initialization sequences have completed. When viewing the HOME PAGE, Radio 1 (Also called FM1 or transceiver #1) is always displayed on the top section. Radio 2 is always displayed on the bottom section. All keypad-initiated operations are performed on the active radio. The active radio easily distinguished by the bright blue color. The cursor is the square box that is located either around the channel number or around the channel alpha identifier. It can be quickly toggled between the channel number and alpha identifier using the cursor knob. The following illustration is an example of what the HOME PAGE looks like. FM 1 Information FM 2 Information CURSOR System Status Information FM 1 Discreet Indicators ACTIVE Channel STANDBY Channel Channel Alpha Identifier The home page is divided into 3 areas FM 1 information (top), FM 2 information (middle), and an area for system status or system prompts (bottom). In the picture above notice that the area in blue contains the information for FM 1. FM 1 will always be on the top. The names FM1, FM2 can be changed in the system setup so that users can change it to something more meaningful like VHF, or MAIN. ACT/SBY - The normal operating mode of the P-2000 is very similar to most ATC COMM radios. The user tunes the Standby channel and then Flip-flops it into the Active channel position using the TRANSFER button. The radio is loaded with Active channel. The standby channel is ONLY used as a scratchpad for selecting the next channel. As an alternative to using the ACTIVE/STANDBY mode, the operator can press and hold the transfer button for 3 seconds and the STANDBY channel will disappear and now the user can tune the active channel directly. Either mode can be selected in the System Setup Mode as the default mode of operation. Notice the square box (CURSOR) around the SBY channel number 104. This indicates the system will tune the Standby channel number. The cursor can be moved around the alpha identifier and channels will be selected alphabetically using the Alpha Identifier. STATUS LINE - The status line is located on the very bottom of the display and it is where the user will be prompted to either input more information via the keypad, or where the Message Indictor will show there is a system message to view. In this case the user should put the MSG button to show the Message page. Page 8 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev. A Discreet Indicators The following discreet indicators apply to both FM1 and FM2. P-2000/C-2000/RT-2000 Operators Manual ACTIVE Channel STANDBY Channel FM 1 Discreet Indicators Channel Alpha Identifier FM1 M TX This helps the user know the information in this block is for the transceiver located in FM #1 Position. This indicates that the audio for that transceiver has been turned muted. To un-mute the audio, change the volume on that radio to something other than 0. This indicates the transceiver is in the transmit mode. RX This indicates the transceiver is receiving a signal. DIR PVT SCAN This indicates the transceiver has been put into DIRECT mode. Direct mode is also called Talk-

around, Car-to-Car, or Simplex. This indicates the transceiver has been put into Private mode and will use the encryption system embedded in the transceiver. This mode is not available if a channel is not programmed for encryption. This indicates the transceiver has been put into Scan mode. You can always get back to the HOME PAGE by pressing the HOME button one or more times. Page 9 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev. A P-2000/C-2000/RT-2000 Operators Manual Turning the System On and Off To power-on the P-2000, press and hold the PWR button (push in the VALUE Knob) for approximately one second and release. Several version number and copyright pages appear on the display while the unit performs a self-test and initializes the attached radio systems. When initialization is complete, the HOME PAGE will appear on the display. To power the P-2000 OFF, press and hold the PWR button for 3 seconds. The following message flashes on the display several times:

Continue to hold the PWR button until the message stops flashing and the display turns off. If aircraft power is removed while the P-2000 is in operation, the P-2000 will store the following information to memory so that when power is re-applied the system will be at the same operating point:

1. Current active and standby channels for FM1 and FM2. 2. Current volume levels for FM1 and FM2. If the operator releases the PWR button prior to 3 seconds elapsing, the display will return its previous state. Page 10 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev. A P-2000/C-2000/RT-2000 Operators Manual Setting the Display Brightness When the user presses the DIM button, the display brightness adjustment display appears. When the value knob is turned clockwise, the display brightness increases in intensity. When the value knob is turned counter clockwise, the display brightness decreases in intensity. The Brightness display disappears when no value knob activity has been present for more than 2 seconds. Setting the Volume Level When you first power on the P-2000, the volume levels for both transceivers will be reset to the level that was active when the unit was powered down. You can change the volume level as follows. When the user turns either of the volume knobs, the volume adjustment display will appear. When the upper volume knob is turned, the volume adjustment display will appear on the upper half of the screen, and will adjust the volume on FM1 transceiver. Likewise, when the lower volume knob is turned, the volume adjustment display will appear on the lower half of the screen, and will adjust the volume on FM2 transceiver. The display below depicts the volume adjustment display when the upper volume knob has been turned. Turning the volume knob clockwise will increase the volume level, while turning the knob counter clockwise will decrease the volume level. The current volume level will be displayed within the display. If the volume is turned all the way down to the off position, the bar will turn red and the Mute indicator will be displayed on the main page. To test the current volume level, press the volume knob and noise should be heard in the headset. The volume adjustment display will automatically disappear if when no knob turning activity has occurred for more than 2 seconds.

A P-2000/C-2000/RT-2000 Operators Manual Selecting a Standby Channel Using the Cursor/Value Knob When the P-2000 first powers on, the selected channels will be set to those that were active when the unit was powered down. To select a different preset channel, do the following:

Using the cursor knob, put the square cursor around the channel number. Turn the value knob until the channel is your desired channel. If you wish to make this your active channel, push the transfer button. Selecting a Channel Using the Keypad Occasionally, it is desirable to select a preset channel by entering its number via the keypad, rather than dialing it in with the cursor/value knobs. This can be performed as follows. When the user presses the CHAN key, the keypad channel entry mode will begin. This mode allows the user to tune a channel by inputting the desired channels number into a field via the keypad. The figure below depicts this mode of channel tuning. If no keypad input is received for more than 4 seconds, the operation will automatically cancel. If the user presses the HOME key, the operation will also cancel. When the user presses the ENTER key, the channel with the number input into the field will be loaded. If the input channel number is invalid, an error tone will sound, and the previous good channel will be reinstated. Page 13 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev. A P-2000/C-2000/RT-2000 Operators Manual Selecting a Channel by Alphanumeric Identifier To change the standby channel using the alpha identifier, use the cursor knob to move the cursor square around the alpha identifier as shown below. Turn the value knob until the channel is your desired channel. Notice that channels change alphabetically. Using the Direct/Repeat Feature The P-2000 supports both direct and repeat modes of operation. Any preset channel that has identical transmit and receive frequencies is considered a direct channel. If the transmit and receive frequencies are different, the P-2000 considers the channel a repeater channel. Repeater channels can be temporarily changed into direct channels by pressing the DIR button. This will temporarily copy the receive frequency into the transmit frequency. The direct mode indicator will light. The following illustration shows radio 1 in direct mode. Direct Mode Indicator NOTE:

Pressing the DIR button on a direct channel has no effect. Page 14 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev.

Changing Transmit Power The P-2000 supports the selection of high and low transmit power. Normally high power is used, however, if interference or other transmit issues are experienced, low power may be selected to help remedy the issue. If you have a radio that supports multiple power levels, such as the RT-5000, you can alter the power setting from the EDIT PAGE as follows. Move the cursor under the transmit power field, as depicted below. Rotate the VALUE knob clockwise once. The power indicator will toggle between high and low with each turn of the VALUE knob. Press the HOME button or the BACK button to exit the mode and return to the normal operating page. Page 20 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev.

A Repeater Mode P-2000/C-2000/RT-2000 Operators Manual Repeater mode is not a specific mode of the P-2000 but an airborne repeater can effectively created by preprogramming specific channels and then using the RELAY MODE. It is also necessary for the two transceivers, FM1 and FM2 to use the same band. In other words, you cannot perform a repeater function with a P-2000 that has FM1 operating in the 136-174 MHz band and FM2 operating in the 800 MHz band. Say a P-2000 channel normally uses a repeater that is not working and an area is without communications on that channel. To act like an airborne repeater the operator must program a special preset channel with the receive and transmit frequencies reversed. We suggest giving this channel a special ALPHA ID that helps the operator recognize it as a special repeater channel associated with the original channel. To operate as an airborne repeater perform the following steps:

While on the HOME PAGE set the ACTIVE channel to the channel you normally use the repeater on FM 1. Put FM1 in DIRECT MODE by pressing the DIR button. Select the special channel associated with the repeater on FM2. Go into the RELAY MODE. If the operator wants to talk select FM2. You can always get back to the HOME PAGE by pressing the HOME button one or more times. Page 24 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev.

A P-2000/C-2000/RT-2000 Operators Manual Encryption Features Turning Encryption On and Off Select FM1 or FM2 depending on which transceiver you what to encrypt. Press the PVT button to toggle encryption on and off. If the P-2000 preset channel being used has been set up for encryption, the privacy indicator will light. PVT Indicator NOTE:

Encryption can only be turned on for channels that have been pre-programmed with an encryption key. Three error beeps will sound if the channel has not been setup for encryption. Selecting an Encryption Key The preset encryption key (sometimes called KEYMAT) for a channel can be temporarily changed as follows. Ensure you are on the HOME PAGE, and the radio you wish to select is active and encryption capable channel is also selected. Press the KEY button. The following illustrates the display when the KEY button was pressed with radio 1 active. If the KEY button is pressed on a channel that has not been preset to use encryption, three warning beeps will sound. Page 26 of 39 P-2000 Operators Manual Oct 2003 Publication No. 150-049105 Rev. A P-2000/C-2000/RT-2000 Operators Manual Rotate the VALUE knob to change the encryption key. A value of PSET indicates you want to use the channels preset encryption key. A numeric value (1-16) indicates you want to override the preset key with the specified key. Press the ENTER button to accept the displayed key. The display will return to the HOME PAGE. When transmitting, a if encryption keys are properly loaded, a tone at the start of the transmission will be generated by the radio and heard by the operator. Begin speaking AFTER the tone or part of your transmission will be lost. When transmitting in the encrypted mode, if you hear a continuous warble tone, this indicates that the encryption key(s) have not been loaded. Either manually enter encryption keys or perform an OTAR if your system has that capability. The newly selected KEYMAT WILL REMAIN even if the channel is changed in effect until power down. Performing an OTAR Ensure you are on the HOME PAGE, and the cursor is on the line of the radio you wish to select and an OTAR capable channel is also selected. Press the OTAR button. The following illustrates the display when the OTAR button was pressed with radio 1 under cursor control. To confirm the start of the OTAR, select YES and press the ENTER button to initiate the OTAR process. The status of the OTAR will be displayed on the radios display line.

A P-2000/C-2000/RT-2000 Operators Manual Steps to Successful Setup and Operation While we would like to pull products out of the box and immediately start to use them, this system is one that takes just little work to get to that point. First READ THE OPERATORS MANUAL!!!! This will familiarize you with the buttons and display pages of the system. The following checklist will help installers setup the P-2000 or C-

2000/RT-2000. 1. Note all part numbers of components in your system.. _______________________________________ _______________________________________ P-2000 Part Number =

C-2000 Part Number =

RT-2000 Part Number = _______________________________________ Please write down the frequency bands of the transceivers inside the P-2000/RT-2000. FM #1 = ___________________ FM #2 = ___________________ 2. Using the SYSTEM Programming page 2, select whether the unit will be operated in Mode 1(only one mic/headset port) or Mode 2 (two independent mic/headset ports). Review the other options and configure as desired. Return to the HOME page. 3. Put the P-2000/RT-2000 in CPS mode for FM #1. 4. Connect a PC to the programming port of the P-2000/RT-2000 and run the Motorola CPS software. 5. Using the CPS software, read the codeplug of FM #1. Save this first in case you need to return to factory settings. 6. Program personalities and Zones/Channels. It is very important to use good channel identifiers so operators can efficiently determine the purpose of the channel. Whenever possible, use the same channel name the ground units use so that when calling out channel changes both the aircraft and the ground units can use the same channel names. These steps require significant knowledge of the Motorola software. We encourage enlisting the help of someone familiar with Motorola CPS software to successfully program the internal transceivers. 7. Save the modified codeplug on the harddrive and then download it into FM1. 8. Do the above for FM #2 if applicable. 9. Upon the exit from CPS mode, the P-2000/RT-2000 will automatically go into LEARN mode. At this time the unit is interrogating the internal transceiver modules for information about channels that were programmed during CPS operations. Wait until the display indicates successful completion of this process. 10. Validate that all channels programmed during CPS are now functional on both FM #1 and FM #2 transceivers.

A P-2000/C-2000/RT-2000 INSTALLATION MANUAL SECTION 2 INSTALLATION 1. General This section contains suggestions and factors to consider before installing the P-2000/C-

2000/RT-2000. Close adherence to these suggestions will assure a more satisfactory performance from the equipment. 2. Unpacking and Inspecting Equipment Exercise extreme care when unpacking the equipment. Make a visual inspection of the units for evidence of damage incurred during shipment. If a claim for damage is to be made, save the shipping container to substantiate the claim. The claim should be promptly filed with the transportation company. It would be advisable to retain the container and packaging material after all equipment has been removed in the event that equipment storage or reshipment should become necessary. 3. Equipment Installation The P-2000/C-2000/RT-2000 installations will conform to standards designated by the customer, installing agency, and existing conditions as to the unit location and type of installation. See Figures 2-1 through 2-7 for an outline drawings of the LRUs, installation tray, and antennas. Before beginning installation the installing agency should review the drawings, electrical interwiring diagram and installation pictorials which are located in this section, and establish requirements to a particular aircraft. A. Cooling Considerations The greatest single contributor to increased reliability of all modern day avionics is limiting the maximum operating temperature of the individual units, whether panel-mounted or remote-

mounted. While modern day circuit designs consume far less electrical energy, the watts per cubic inch dissipated within the avionics units still remains much the same due to high density packaging techniques utilized. Consequently, the importance of providing avionics cooling is essential to the life span of the unit. The combined heat load of several units operating in a typical avionics location will significantly degrade the reliability of the avionics if provisions for cooling are not incorporated in the initial installation. Failure to provide cooling will certainly lead to increased avionics maintenance costs and may void the Wulfsberg warranty. B. P-2000 Mechanical Installation

(1) Select the P-2000 mounting location. Insure that unit will be easily accessible and clearly visible to the operator. The location should be free from excessive moisture, vibration, heat and noise generating sources. The unit has standard Dzus mount dimensions as shown in Figure 2-1. Allow adequate space and service loops for installation of cables and connectors. Publication No. 150-049106 Rev. A Page 15 of 41 P-2000 Installation Manual Oct 2003 P-2000/C-2000/RT-2000 Installation Manual

(2) The installing agency will supply and fabricate all external cables. The connectors are supplied separately and are listed in Section 1.F.

(3) The length and routing of the external cables must be carefrully studied and planned before attempting actual installation. Avoid sharp bends and placing cables too near other aircraft cables.

(4) Use only recommended wire sizes and wire type for interwiring. Wire sizes and wire type are listed on the interwiring diagrams. C. C-2000 Mechanical Installation

(1) Select the P-2000 mounting location. Insure that unit will be easily accessible and clearly visible to the operator. The location should be free from excessive moisture, vibration, heat and noise generating sources. The unit has standard Dzus mount dimensions as shown in Figure 2-1. Allow adequate space and service loops for installation of cables and connectors.

(4) Use only recommended wire sizes and wire type for interwiring. Wire sizes and wire type are listed on the interwiring diagrams. D. RT-2000 Mechanical Installation

(1) Select the RT-2000 mounting location. The location should be free from excessive moisture, vibration, heat and noise generating sources. The unit can be rigidly mounted. Allow at least one inch of free air space around the top and rear of the unit and one-half inch along each side. Allow adequate space for installation of cables and connectors.

(2) Refer to Figure 2-3 for the RT-2000 mounting dimensions.

(3) Mark, punch, and drill the mounting holes. Care must be taken to avoid damage to adjacent equipment or cables.

(4) Secure the mounting tray firmly in place.

(5) Secure the RT-2000 to the mounting tray and connect all appropriate connectors taking care to apply the correct RF connector to the desired transceiver. Page 16 of 41 P-2000 Installation Manual Oct 2003 Publication No. 150-049106 Rev. A P-2000/C-2000/RT-2000 INSTALLATION MANUAL E. Antenna Mechanical Installation

(1) Antenna installation is critical to the range and quality of the transmitted signal. Care should be taken to keep all antennas a separated as possible. A minimum of 70 cm should be observed if possible.

(2) Whenever possible, mount antennas on the bottom of the aircraft. The only exception is if two antennas covering the same frequency band are used, put one on the top of the aircraft and the other on the bottom to achieve maximum isolation. If this is not possible, put on the front of the aircraft and one on the rear.

(3) The antennas should be mounted on a flat metal surface to obtain a proper ground plane. Ensure the antenna is adequately grounded to the aircraft skin (<5 mohm is a standard rule of thumb).

(4) P-2000/RT-2000 antennas should be mounted a minimum of 20 cm from each other.

(5) Wulfsberg recommends the use of RG-193 on most installations. Installers can substitute other types of coax than RG-193 to get better performance especially at higher frequencies. Be aware that each type of coaxial cable requires specific connectors that may only be available from the coaxial cable manufacturer. Publication No. 150-049106 Rev.

General Information The Flexcomm 2000 family of products provide for many installation options. Normally the requirements can be determined by answering the following questions.

(1) Does the user want a transceiver that is remote mounted or panel mounted?

This determines whether a P-2000 (panel mount) or a RT-2000 (Remote mount) transceiver will be used. If a RT-2000 remote mount transceiver is used, then at least one C-2000 control head must also be specified. Additional C-2000's can be added for control of the RT-2000 from remote locations. If a P-2000 panel mount transceiver is desired then additional C-2000's can be added for control of the P-2000 from remote locations.

(2) How many channels must be monitored at a time - one or two?

This determines how many Internal Transceiver Modules (ITMs) are inside the P-

2000 or the RT-2000. The P-2000 and RT-2000 can have one or two ITM's. If the transceiver has two ITM's, then the user has the choice of using one or two mic/headset ports. Usually this is determined by the number of audio panel ports available for FM tactical radios. In new installations it is recommended that two audio ports be used so that each ITM can be accessed independently by two operators. For retrofit installations, one port can be used to access both ITM's. If only one microphone/headset port is available, then connect it to FM 1 mic/headset port on the transceiver. The user will then need to select using the P-

2000 or C-2000 front panel controls which ITM to use for transmit. The receive audio from both ITM's will be summed together and output on FM 1 Headset Port. If two positions on the audio panel are available, then connect the 1st position to FM 1 mic/headset and position #2 to FM 2 mic/headset. This will allow for two users to independently operate the two ITM's.

(3) Does the audio panel have individual RX audio volume controls?

If yes, then the P-2000 or C-2000 can have the volume controls programmed by the installer to a set level that the user will not be able to change via the volume knobs on the front of the P-2000/C-2000. In this case, the user will go to the audio panel to change the volume - not the P-2000 or C-2000. Page 26 of 41 P-2000 Installation Manual Oct 2003 Publication No. 150-049106 Rev. A 2. Sample System Block Diagrams P-2000/C-2000/RT-2000 INSTALLATION MANUAL The following block diagrams are intended to show various installation configurations of the 2000 family of products. Due to the flexibility of the system components it is impossible to create wiring diagrams for all configurations. However, with the examples given by the manufacturer and the technical descriptions of connector pins, a competent designer should be able to create wiring diagrams for their specific application. Figure 3.1 shows diagrams that use a single P-2000 and Single C-2000/RT-2000. They attempt to show how single and multiple Mic/Headset interfaces can be used. Figure 3.2 shows diagrams that use a combination of C-2000 control units and P-2000/RT-2000 transceivers with audio panels without volume controls.

A P-2000/C-2000/RT-2000 INSTALLATION MANUAL SECTION 5 Continued Airworthiness Instructions Introduction This document contains instructions for testing a FLEXCOMM 200 system on a periodic maintenance cycle to assure continuous airworthiness. This document is intended to supplement the individual installation and user manuals of the Flexcomm 2000 system components. The aircraft maintenance personnel should be in possession of and refer to these manuals during inspections. The Flexcomm 2000 system includes a P-2000 panel mount transceiver or a C-2000 control head and a RT-2000 remote mount transceiver and suitable antennas. The recommended maintenance cycle is one year. Equipment To perform the checkout procedures described below, you must have the following:

A HP 8920 Communications Service Monitor or equivalent to transmit and receive over the programmed frequencies. An AT-150 or equivalent broad band antenna or single band antennas covering the same frequencies of the unit under test. Miscellaneous cables and adapters. A handset interfaced to the FLEXCOMM 2000 system. Four wire Ohmmeter. NOTE: Calibration or internal LRU adjustments are only required on failure condition of the equipment under test. Antenna Verification The bonding of all antennas and the radio chassis to the airframe should be verified to have an impedance of less than 0.1 Ohm. The VSWR of the combined antenna and coax cable should be measured at the connector to the radio. The VSWR should be no more than the maximum specified antenna 2.5:1. Transmitter Verification 1. Select a channel with known Receive and Transmit frequencies on FM1. 2. Set the Service Monitor to receive the transmit frequency of the selected channel. Connect the output of the radio under test to the Service Monitor RF input port with a cable less than three feet in length (refer to the Service Monitor Users Manual). 3. Use the handset interfaced to the FLEXCOMM 2000 system to transmit a signal, modulated from the Service Monitor. Publication No. 150-049106 Rev. A Page 39 of 41 P-2000 Installation Manual Oct 2003 P-2000/C-2000/RT-2000 Installation Manual 4. Measure the output power, output frequency, and FM modulation (kHz deviation) with the Service Monitor. Verify that the output frequency and power are within specification. Adjust or repair as necessary. 5. Repeat for FM2 transceiver. Receiver Verification 1. Select a channel with known Receive and Transmit frequencies on FM1. 2. Set the Service Monitor to transmit at the frequency programmed on the test unit with a 1 kHz tone with 3 kHz deviation for FM mode. If necessary, refer to the users manual supplied with the Service Monitor. 3. Connect the output of the radio to the RF input port with a cable less than three feet in length. Set the output power of the Service Monitor to the specified sensitivity level of the radio under test. 4. With the proper cables, route the headset audio back into the Service Monitor. Push the FM1 Volume button to open the squelch and measure SINAD. SINAD should be better than 12 dB for FM. 5. Increase the RF signal by 10 dB and verify that the squelch gate opens. 6. Repeat for FM2 if available. Final System Check-out 1. Reconnect the coax cable connecting the radio to the antenna. 2. Place an AT-150 or similar broad band antenna 10 feet from the aircraft antenna. The antenna should be at the same elevation and have the same polarity as the antenna on the aircraft. 3. Connect the antenna to the Service Monitor set to receiver at the desired frequency of test. 4. Transmit over FM1 on the test frequency and measure the received signal power. 5. The insertion loss should be between 30 and 40 dB @ 150 MHz. Substitution of the receiving antenna or changes in antenna placement can significantly effect measurement results. 6. Record the actual values measured and the measurement setup. Use this information to track any degradation in the antenna system on future system checkouts. 7. Repeat for FM2.

Introduction There are two configuration settings that may need to be set by the installer before operational use. 1. Configuration Settings The followings lists the configuration settings available in the P-2000/C-2000 that a installer must set properly based on the system design. Please use instructions displayed in the P-2000/C-

2000/RT-2000 Operators Manual for instructions on how to change these settings. Factory settings are shown below.

(1) MIC MODE (DUAL/SINGLE) There are two Mic mode settings depending on how many audio panel positions are available. Mode 1 or SINGLE is used when there is only one mic/headset position on the audio panel. In this case, the audio from both FM1 and FM2 will be summed together during receive and sent to FM1 Headset pins. Likewise microphone audio should be connected to FM1 Mic inputs and the operator will transmit on whichever transceiver is the active transceiver. The active transceiver is easily distinguished by the area of the display that has a bright blue background. Mode 2 or Dual is used when there are two mic/headset positions on the audio panel dedicated to the P-2000 system. In this case the audio from FM1 is sent to and from FM 1 Mic/Headset pins. Audio from FM2 is sent to and from FM2 Mic/Headset pins. The receive audio from each transceiver is kept separate. In this case the designation of a transceiver, FM1 or FM2 as the active transceiver only means the knobs and buttons will operate on that transceiver. The user selects which transceiver FM1 or FM2 via the audio panel. FACTORY SETTING= DUAL.

(2) LOCK VOLUME (NO/YES) If the installer has designed the system with audio panels that do not have volume controls, this value should be set to NO. When audio panels have volume controls, it is left to the installer/user to determine if theyd like the volume pots on the P-2000 to be disabled so that there is only one location in the system for volume control the audio panel. In this case set this value to YES. FACTORY SETTING= NO Publication No. 150-049106 Rev. A Page 41 of 41 P-2000 Installation Manual Oct 2003

C-2000/RT-2000 Operators Manual The Wulfsberg "2000" family of Flexcomm products are comprised of the P-2000 panel mount transceiver and the RT-2000 remote mount transceiver which is controlled by the C-2000 control head. The P-2000 and RT-2000 are capable of being populated with one or two ITM's (Internal Transceiver Modules) covering any combination of the following frequency bands: VHF 136-174 MHz, UHF -1 (403-470 MHz), UHF -2 (450-520 MHz) and UHF800

(806-870 MHz). For applications where multiple points of user operation are required, one or more C-2000's can be added. For purposes of this manual the term "P-2000" shall be used to describe a P-2000 or C-2000/RT-2000 installation. The features and user interface are identical in both systems. Features The P-2000 provides a host of powerful features, including:

Multi-band operations: One or Two ITM's covering any combination of the following frequency bands:

136 - 174 MHz (10/1 Watt Transmit Power) 403 - 470 MHz (10/1 Watt Transmit Power) 450 - 520 MHz (10/1 Watt Transmit Power) 806 - 870 MHz (3/1 Watt Transmit Power) Clear and bright Color LCD display showing Active/Standby channel selection along with other critical operational information. 255 Preset channel memory in each internal transceiver module. The powerful yet incredibly simple user interface that allows the user to select channels using the firm tactile feedback keypad or rotary knobs. Modulation types available in the P-2000 include FM analog, P25 Digital conventional, P25 Trunking and Motorola 3600 Baud Trunking. Transceivers are capable of operating on 12.5 kHz, 20.0 kHz, and 25.0 kHz channels depending on options. Multiple types of encryption are available as options (AES, DES, DES-XL, DES-OFB, DVP and DVI). In addition, MDC1200 OTAR and P25 OTAR are standard in all models that include encryption capability. One or Two microphone/headset interfaces are supported. This provides retrofit applications the ability to use both transceivers even if only one microphone/headset port is available on the aircraft audio panel system. If two microphone/headset ports are used, the P-2000 is capable of independent operation of each ITM. In other words, one user can be operating on FM1 while the other user independently uses FM2. Advanced multi-radio modes, such as Relay, Simulcast and Relay-Simulcast. Programming port on the front of the panel allows for computer loading of channel information and encryption key loading. Wulfsberg's exclusive QMEM (Quick Memory) function allows for fast access to preset memory channels. Document 150-041102 Revision A Page 3 of 37 Wulfsberg Electronics P-2000 and C-2000/RT-2000 Operators Manual Transceiver Overview The Wulfsberg 2000 family of radio products is a group of FM Tactical transceivers that incorporate one or two transceiver modules and control functions into a single panel mount unit (P-2000) or a panel mount control head

(C-2000) and remote mount RT-2000 Transceiver. Part number variations of the unit exist for any combination of the following frequency bands: 138-174 MHz, 403-470 MHz, 450-520 MHz, and 806-870 MHz. Each transceiver module, with the exception of the 806-870 MHz band, can transmit with either 1 or 10 watts transmit power. The 800 MHz unit produces either 1 or 3 watts transmit power. The P-2000 can operate by itself or in conjunction with the C-2000 control display acting as a remote slave control. Input voltage is 28 volts DC and the keypad is backlit from either 28VDC, 5 VDC or 5 VRMS AC. The Wulfsberg C-2000 is a control display unit that can be used as a slave control head with a P-2000 panel mount transceiver, or as either a primary or slave control head for the RT- 2000 remote transceiver. Versions of the C-2000 include black faceplate and options for either Standard or NVG compatible displays. Input voltage is 28 volts DC and the keypad is backlit from either 28 VDC, 5 VDC or 5 VRMS. The Wulfsberg RT-2000 is a remote mounted transceiver that incorporates one or two transceiver modules in a remote mounted unit. It must be controlled by at least one C-2000 control head. Additional C-2000's can be added to the system for multi-positional control of the transceiver. The P-2000 or C-2000/RT-2000 systems operate identically with the exception of the PC/Keyloading interface. For a P-2000 the interface is located on the front of the P-2000. In a C-2000/RT-2000 system, the connector on the RT-2000 is used for PC/Keyloading functions. The connector on the C-2000 is not currently used. NOTE:

For the purposes of this operators manual the use of the phrase P-2000 will be used to cover both P-2000 and C-2000/RT-2000 systems.

Document 150-041102 Revision A Page 6 of 37 Wulfsberg Electronics P-2000 and C-2000/RT-2000 Operators Manual The Home Page The HOME PAGE is the primary operational page of the P-2000. The HOME PAGE becomes visible when the P-2000 is ready for user input, immediately after the power up and initialization sequences have completed. When viewing the HOME PAGE, Radio 1 (Also called FM1 or Transceiver #1) is always displayed on the top section. Radio 2 is always displayed on the bottom section. All keypad-initiated operations are performed on the active radio. The active radio easily distinguished by the bright blue color. The cursor is the square box that is located either around the channel number or around the channel alpha identifier. It can be quickly toggled between the channel number and alpha identifier using the Select Knob. The following illustration is an example of what the HOME PAGE looks like. CURSOR FM 1 Information FM 2 Information FM 1 Discreet Indicators ACTIVE Channel STANDBY Channel Channel Alpha Identifier System Status Information The home page is divided into 3 areas FM 1 information (top), FM 2 information (middle), and an area for system status or system prompts (bottom). Notice in the picture above that the area in blue contains the information for FM 1. FM 1 will always be on the top. The names FM1, FM2 can be changed in the system setup so that users can change it to something more meaningful to their use such as VHF or MAIN. ACT/SBY - The normal operating mode of the P-2000 is very similar to most ATC COMM radios. The user tunes the Standby channel and then flip-flops it into the Active channel position using the TRANSFER button. The radio is loaded with Active channel. The standby channel is ONLY used as a scratchpad for selecting the next channel. As an alternative to using the ACTIVE/STANDBY mode, the operator can press and hold the transfer button for 3 seconds and the STANDBY channel will disappear and now the user can tune the active channel directly. Either mode can be selected in the System Setup Mode as the default mode of operation. Notice the square box (CURSOR) around the SBY channel number 104. This indicates the system will tune the Standby channel number. The cursor can be moved around the Alpha Identifier and channels will be selected alphabetically. STATUS LINE - The status line is located on the very bottom of the display and it is where the user will be prompted to either input more information via the keypad. It is also used to display the Message Indictor used to show there is a system message to view. In this case the user should put the MSG button to show the Message page. Document 150-041102 Revision A Page 7 of 37 Wulfsberg Electronics P-2000 and C-2000/RT-2000 Operators Manual Discreet Indicators The following discreet indicators apply to both FM1 and FM2. ACTIVE Channel STANDBY Channel FM 1 Discreet Indicators Channel Alpha Identifier FM1 M TX This helps the user know the information in this block is for the transceiver located in FM #1 Position. This indicates that the audio for that transceiver has been turned muted. To un-mute the audio, change the volume on that radio to something other than 0. This indicates the transceiver is in the transmit mode. RX This indicates the transceiver is receiving a signal. DIR PVT SCAN This indicates the transceiver has been put into DIRECT mode. Direct mode is also called Talk-

around, Car-to-Car, or Simplex. This indicates the transceiver has been put into Private mode and will use the encryption system embedded in the transceiver. This mode is not available if a channel is not programmed for encryption. This indicates the transceiver has been put into Scan mode. You can always get back to the HOME PAGE by pressing the HOME button one or more times.

Document 150-041102 Revision A Page 22 of 37 Wulfsberg Electronics P-2000 and C-2000/RT-2000 Operators Manual Repeater Mode Repeater mode is not a specific mode of the P-2000 but an airborne repeater can effectively created by preprogramming specific channels and then using the RELAY MODE. It is also necessary for the two transceivers, FM1 and FM2 to use the same band. In other words, you cannot perform a repeater function with a P-2000 that has FM1 operating in the 136-174 MHz band and FM2 operating in the 800 MHz band. Say a P-2000 channel normally uses a repeater that is not working and an area is without communications on that channel. To act like an airborne repeater the operator must program a special preset channel with the receive and transmit frequencies reversed. We suggest giving this channel a special ALPHA ID that helps the operator recognize it as a special repeater channel associated with the original channel. To operate as an airborne repeater perform the following steps:

While on the HOME PAGE set the ACTIVE channel to the channel you normally use the repeater on FM 1. Put FM1 in DIRECT MODE by pressing the DIR button. Select the special channel associated with the repeater on FM2. Go into the RELAY MODE. If the operator wants to talk select FM2. You can always get back to the HOME PAGE by pressing the HOME button one or more times.

Using the CPS software, read the FM1 and save the file as sent by the Wulfsberg Factory for backup purposes. Perform any changes to the archive file such as adding/deleting channels, changing encryption options etc. For the P-2000 to function properly DO NOT change key button options or display options. Also, the Zone/Channel assignment must be made so that there no more than 16 channels per zone. Document 150-041102 Revision A Page 30 of 37 Wulfsberg Electronics P-2000 and C-2000/RT-2000 Operators Manual Once all new channels have been entered, transfer the updated archive back into the P-2000. The Motorola software will indicate successful completion of this task. Perform the above actions on both FM1 and FM2. Press the HOME button once to enter the LEARN MODE. In this mode, the P-2000 computer interrogates the internal transceivers to determine what changes have been made and to update its internal memory. This process can take several minutes. The operator will be shown progress as the system completes its task. This task must be successfully performed or the P-2000 main processor will not be able to properly function with the internal transceivers. Upon successful completion of the LEARN mode, press the HOME button several times to return to the HOME page. You can always get back to the HOME PAGE by pressing the HOME button one or more times.

Document 150-041102 Revision A Page 36 of 37 Wulfsberg Electronics P-2000 and C-2000/RT-2000 Operators Manual Steps to Successful Setup and Operation While we would like to pull products out of the box and immediately start to use them, this system is one that takes just little work to get to that point. First READ THE OPERATORS MANUAL!!! This will familiarize you with the buttons and display pages of the system. The following checklist will help installers setup the P-2000 or C-2000/RT-2000. 1. Note all part numbers of components in your system.. P-2000 Part Number =

_______________________________________ C-2000 Part Number =

_______________________________________ RT-2000 Part Number = _______________________________________ Please write down the frequency bands of the transceivers inside the P-2000/RT-2000. FM #1 = ___________________ FM #2 = ___________________ 2. Using the SYSTEM Programming page 2, select whether the unit will be operated in Mode 1(only one mic/headset port) or Mode 2 (two independent mic/headset ports). Review the other options and configure as desired. Return to the HOME page. 3. Put the P-2000/RT-2000 in CPS mode for FM #1. 4. Connect a PC to the programming port of the P-2000/RT-2000 and run the Motorola CPS software. 5. Using the CPS software, read the codeplug of FM #1. Save this first in case you need to return to factory settings. 6. Program personalities and Zones/Channels. It is very important to use good channel identifiers so operators can efficiently determine the purpose of the channel. Whenever possible, use the same channel name the ground units use so that when calling out channel changes both the aircraft and the ground units can use the same channel names. These steps require significant knowledge of the Motorola software. We encourage enlisting the help of someone familiar with Motorola CPS software to successfully program the internal transceivers. 7. Save the modified codeplug on the hard drive and then download it into FM1. 8. Do the above for FM #2 if applicable. 9. Upon the exit from CPS mode, the P-2000/RT-2000 will automatically go into LEARN mode. At this time the unit is interrogating the internal transceiver modules for information about channels that were programmed during CPS operations. Wait until the display indicates successful completion of this process. 10. Validate that all channels programmed during CPS are now functional on both FM #1 and FM #2 transceivers.
