Introduction The Eclipse2 series product range is a radio platform that provides an array of features and applications. The IP Commander software is used to monitor and configure a range of parameters, within the Eclipse2 Transceiver Modules, via the local USB port or remotely using the Internet Protocol over Ethernet. IP Commander is a platform independent application, written in Java, and will run on many operating systems, including all versions of Microsoft Windows, Apple MAC OS and Linux. IP Commander can additionally calibrate and update the Eclipse2 Transceiver Module firmware via USB or remotely over Ethernet. 2. Getting Started 2.1. Connection To physically connect the computer running IP Commander to the Eclipse2 Transceiver Module, use the front mounted USB connector or the rear mounted Ethernet socket. A standard Type A USB cable or RJ45 terminated Ethernet cable is required to connect to the Eclipse2 Transceiver module. Note that the USB connection is not supported under Microsoft Vista. The Eclipse2 has a preconfigured IP address of 192.168.1.201, however customers can specify their own IP addresses at time of order. Ensure that the computer, on which IP commander is running, is on the same IP network as the Transceiver Module. The network mask will be 192.168.1.XXX when using the Transceiver Modules default IP address. If you are unable to connect via the Ethernet connection or if the IP Address is unknown, you can still connect by using the front panel mounted USB port. The IP Address can be reset to a value of 192.168.1.201 by simultaneously pressing, and holding, the front panel speaker and microphones PTT buttons, for five seconds. NOTE: The IP Address reset sequence will not work if the front panel is disabled.

Users The User Configuration menu allows you to add, delete or edit additional users from the table. NOTE: There must be at least one entry in the list with the access level set to Administrator. Figure 7 User Configuration Menu ECLIPSE2 IPCommander User Manual 12 4.2. Base Station Software IP Commander can perform an update or rollback of the base station software. The Eclipse2 contains two copies of the firmware image, one active and one inactive. During a software upgrade, the new version is copied to the inactive memory location, only becoming active after a successful installation. If an upgrade is interrupted, the original firmware will continue to be active. The software upgrade is carried out using the local USB port or remotely using the Ethernet connection. The firmware files are supplied with a filename in the following format:

firmware_1_8_0.esw The filename determines the version number; in the above example, the Version number is 1.8.0 and the file extension .esw indicates that it is an Eclipse2 software file. To upload a new firmware file click Upload and select the firmware file and click Apply. Once the upload has been completed, the base station will save the current base station configuration and deploy the new firmware image. When the new firmware has been deployed, click OK to reboot the base station. During the reboot process, the base station will make the new firmware active and load the configuration, which was automatically saved from the previous firmware. A firmware update will take approximately two minutes to complete. To rollback the firmware back to the previous version, select the inactive version and click Apply. Figure 8 Base Station Software Upload 4.3. Backup and Restore This process allows the saving and restoration of the base station non-volatile configuration ECLIPSE2 IPCommander User Manual 13 data, including the signal map and channel profiles. 4.3.1. Backup To start the Backup process select Backup/Restore from the Admin menu, then type a filename for the backup file. Click Save and the backup process will start. The backup process will take approximately two minutes to complete. The backup file will have a default format of base_station_name@xxx.xxx.xxx.xxx.ebs Where base_station_name is the text from the networking name field xxx.xxx.xxx.xxx is the IP Address of the base station. ebs is the file extension of the backup file. However, the Backup file can be changed to any name provided the file extension remains as .ebs 4.3.2. Restore To start the Restore process select Backup/Restore from the Admin menu, then select a previously saved backup file, click Open and the Restore process will start. The restore process will take approximately two minutes to complete. Figure 9 Base Station Configuration Restore 4.4.

To change channels click on the Up or Down arrows on the Channel field and click the Apply button. 5.2. Networking The Networking field displays, and allows the configuration of, the parameters required for IP networking: the current base station name, IP address, subnet mask and gateway IP. Name: Specifies the name of the base station. IP: The IP Address of the base station. This is the IP Address to which IP Commander will connect. Mask: The subnet mask of the base station. The subnet mask defines which IP addresses are to be treated as being inside the LAN, and which are outside the LAN. Gate: The gateway IP, or default route, for the base station. A value of 0.0.0.0 means there is no default route. The gateway IP is the address to which traffic destined outside the LAN will be sent to. Changes to these fields require that the base station be rebooted, for the new network settings to be accepted and to take effect. On pressing the Apply button, the user will be asked if it is okay to reboot the Eclipse2. If a reboot is declined, the changes will be ECLIPSE2 IPCommander User Manual 17 discarded and the current settings retained. 5.3.

TX VCO Shows the current TX VCO tuning voltage and PLL frequency. 5.18. TX P25 NAC Displays the current TX NAC. Only displayed when the C4FM modulator is present on the signal map. 5.19. Voting In-base voting is used to determine the base station with the best incoming signal, and to pass the signal from that base station to other bases. It is recommended that base stations be part of same IP multicast group. When the base stations are receiving, they send their RSSI values to each other. One of the base stations will determine that it has the highest RSSI value, become the master base station and then inform all the other base stations that they are slaves. The slave base stations will listen for audio packets from the master base station, for the duration of the call, until the following conditions arise:

1. The masters RSSI value falls below -107dbm, in which case a new master base station will be assigned 2. All the base stations stop receiving, which will invoke a restart of the voting process 3. The master base station stops receiving and a new master is assigned Base Stations can join or leave the multicast group without causing system failure. (no permanently assigned master). This type of voting architecture is distributed, thus no central voting comparator is required. The Audio packets are sent only from the master to the slaves, the master base station transmitting its own received audio locally. The data rate of a stream is approximately 100Kbps using the G711 audio codec, thus only 100kbps per base station is required. Comparing the above distributed voting to the use a central voting comparator, for a central comparator ALL audio packets are routed via the voter for processing. Since there are now separate receive and transmit audio paths required per base station, the required data rate (and consequently bandwidth) is doubled to 200kbps per base station.

Signals The Signals menu panel provides a visual tool with which to configure the Signal Map. Within the signal map, various Function Blocks are placed and interconnected to set the required base station controls and features. An example signal map is shown in Figure 12. Figure 12 Signals Panel 6.1. Using the Signal Map The Signal map configures the Eclipse2 by using various function blocks to form a base station or repeater. Configuring the signal map is carried out by using a drag and drop interface. To insert a function, select an item using the mouse from the right side panel and drag it onto the map. To remove a function block from the map, right click the item and select Remove. To connect the function blocks together click the small red square in the centre of one function and drag a line to the next function down the chain. Note: Function Blocks have directional inputs and outputs. Outputs can only be connected to inputs. Some functions, like the FM Demodulator, have only an output. For example when drawing a connecting line start at the FM Demodulator and drag it to the Tone Decoder, not the reverse. If the Error message Target Block does not have Input is displayed, try drawing the connection line in the reverse direction between the blocks. ECLIPSE2 IPCommander User Manual 22 The output of each function block can be connected to the inputs of multiple function blocks, to a maximum of ten. To do this, repeat the dragging operation, from the small red square, for each desired output connection. Under these circumstances, the input to each block is identical, the single output being simultaneously copied to each of the function block inputs. Signal Maps can also be saved to a file and reused to configure another base station. To save a configuration click the Save As button and type a filename name and click Save. If a configuration does not fit within the signal map window, use the Zoom Out or Zoom In buttons to resize the window so that all the function blocks are visible. Should the configuration be no longer visible, click the Zoom its default magnification. button to reset the Signal Map back to Figure 13 Signal Map Function blocks have fixed properties and variable parameters, such as:

The TX NAC code is set via the channel menu. The modulator can send P25 voice and data messages, as well as Trunking Signalling Blocks

(TSBKs). 6.2.24. Talkgroup Out (VoIP/RoIP) Using the Talkgroup Out function enables EclipseNet functionality as per TIA-102.BAHA APCO P25 DFSI/AFSI. DFSI will be enabled when the Talkgroup In function is driven by a P25 block, and AFSI will be enabled when driven by a PCM/analog block. To enable Multicast VoIP operation, drag the Talkgroup Out function block onto the signal map, right click, select Edit, enter a valid IP address and port number. Multicast IP addresses are in the range of 224.0.0.0 to 239.255.255.255. Multicast Port Numbers for RTP have a default of 9000 and if changed must be an even number eg: 9000, 9002, 9004, 9006 etc. To enable Unicast VoIP operation, drag the Talkgroup Out function block onto the signal map, right click, select Edit, enter a valid IP address and port number. Unicast IP addresses for private WAN or LAN networks are in the range of:

10.0.0.0 10.255.255.255 172.16.0.0 172.31.255.255 192.168.0.0 192.168.255.255 Unicast Port Numbers use the following formats:

RTP: must be an even number starting from 9000 eg: 9000, 9002, 9004 etc. RTCP: The RTCP port number is automatically set. The port number is an odd number and is always higher in value by one than the RTP port. For example if the RTP port is 9002 then the RTCP port will be automatically set to 9003. Control: The Control port number is automatically defined by the RTP port minus 2000. For Example if the RTP port is 9004, then the Control port will be set to 7004. For detailed configuration on EclipseNet consult the Eclipse2 Application Guide. 6.2.25. Talkgroup IN (VoIP/RoIP) Using the Talkgroup In function enables EclipseNet functionality as per TIA-102.BAHA ECLIPSE2 IPCommander User Manual 30 DFSI/AFSI. DFSI will be enabled when the Talkgroup In function is driving a P25 block, and AFSI will be enabled when driving a PCM/analog block. To setup Talkgroup In, drag the function block onto the signal map, right click, select Edit and enter a valid port number, corresponding to an appropriate Talkgroup Out RTP port number, for Unicast, or a valid IP address and port number, for Multicast. For detailed configuration on EclipseNet consult the Eclipse2 Application Guide. 6.2.26. Multi-Tone Decoder Provides CTCSS and DCS decoding. The output of this block is audio with the CTCSS/DCS tones filtered out by a high pass filter, with a 300Hz cut-off frequency. The output is active only when the corresponding CTCSS/DCS signal is detected at the input. A standard DCS/CTCSS EIA Tone set is used, with tones in the frequency range 67.0Hz to 254.0Hz. The frequency of the decoder is set by editing the icon on the signal graph. Instantiate one multi-tone decoder for each frequency to be decoded, setting each instance to a different frequency. Up to ten different frequencies may be decoded. A typical configuration connects this block after the FM Demodulator, the output of the demodulator being connected in a parallel configuration to the input of each decoder. The output of each decoder may be processed independently, or summed and fed into a common signal path. 6.2.27. Multi-Tone Encoder Provides CTCSS and DCS encoding. This block uses the standard DCS/CTCSS EIA Toneset, with frequencies ranging from 67.0Hz to 254.0Hz. The frequency of the encoder is set by editing the icon on the signal graph. Instantiate one multi-tone encoder for each frequency to be encoded, setting each instance to a different frequency. Up to ten different frequencies may be encoded. The deviation levels are set via the channel menu: 12.5KHz Channel = 250Hz and 25KHz Channel = 500Hz. The CTCSS block supports Reverse Tone Burst and a programmable No Tone Period, at the end of transmission, from 0 to 999ms, set via the channel menu. A typical configuration connects this block before the FM Modulator. The encoder output for each frequency should be summed and fed into the modulator. The input of each encoder may be from an independent signal path, or a single path may be split and connected to the encoder inputs, in parallel. ECLIPSE2 IPCommander User Manual 31 6.2.28. Continuous Wave Identification This block periodically inserts a Morse code identifier into an audio stream. It has one input and one output. The input is the audio stream into which the identifier is to be inserted. The output is the audio stream, with the identifier inserted. The period between identifiers, the speed of the Morse Code, the frequency of the CW tone and the message being sent are set in the transmitter profile, on a per channel basis. Further details are in section 7.10. The CWID block will only insert audio when the incoming audio stream is inactive, meaning the identifier will never interrupt a call. If the audio is active when the next identifier is due, the identifier will be sent at the first opportunity, after the audio becomes idle. If the transmission of an identifier is interrupted by a call, it will be retransmitted at the first opportunity, until it has been sent in its entirety. If the identifier is to be override a call, leave the input to the CWID block disconnected, and use either a priority or addition block to mix the output of the CWID block into the audio stream. The CWID Block uses the International Morse Code, as in Table 1. Table 1: CWID Morse code alphabet Character Code A B C D E F G H I J K L M

6.2.29. Digital Input/Output This block generates a verbal announcement in response to an external digital input. It has a single output, which is active whenever the alarm message is being spoken. The message ECLIPSE2 IPCommander User Manual 32 will be periodically repeated, for as long as the input remains active. The external input which is used as the trigger, the polarity of the external input, the text of the message and the repetition period of the alarm message are all programmable. Optionally, the external input can also be used to active an alarm within the Eclispe2s alarm subsystem. This User Defined alarm will generate warnings and an SNMP trap, like any other alarm in the Eclipse2. Up to two digital I/O blocks may be instantiated. A list of the external inputs which may be monitored, along with their mnemonics, is given in Table 2. The mnemonic is the text which is to be entered in the pin field of the I/O block, causing the corresponding pin to be monitored. Table 2: External inputs which may be monitored Function RX PLL locked TX PLL locked Up button on front panel Right button on front panel Down button on front panel Left button on front panel Status button on front panel PTT button on front panel Microphone PTT input E&M PTT input TTL PTT from backplane External squelch input General Purpose Input from backplane Mnemonic RXPLL TXPLL FPUP FPRIGHT FPDOWN FPLEFT FPSTATUS FPPTT MICPTT EMPTT TTLPTT EXTSQ GPI GPIO pins can also be monitored by specifying a register name and bit position. Such labels are of the form rNN, where r is a letter in the range A to D and nn is a number in the range zero to 31. The mapping of GPIO bit positions to functions is not guaranteed to be constant, so the mnemonics of Table 2 are preferred. The state field specifies whether the high or low state of the input being monitored is to be considered asserted. The message will be spoken while the input is asserted. The text field contains the text of the message to be spoken. It may contain alphanumeric characters and spaces. The Eclipse2 system will convert this text into spoken word, using an in-built speech synthesiser. If the text field is left blank, the audio output of the I/O block will be disabled. Any audio from the Eclipse2 alarm system will not be disabled. The period field specifies how often the message will be repeated. The message will be periodically repeated, until the input being monitored becomes unasserted. The alarm field specifies whether an asserted input is to trigger an alarm within the Eclipse2. A zero in this field means an alarm will not be generated. A value of one means an alarm will be generated when the external input is asserted. The generated alarm is labelled User Defined in the Eclipse2 alarm system. Like any other alarm, the User Defined may be monitored via SNMP, IP Commander or audio. If multiple IO blocks are instantiated, an ECLIPSE2 IPCommander User Manual 33 alarm is generated by the logical OR, of the state of each IO block that has alarming enabled. ECLIPSE2 IPCommander User Manual 34 7. Channels The Channel menu configures the following fields:

Transmit and Receive Frequencies CTCSS and DCS encode and decode tones Channel Name Channel Number (max 256 Channels) Channel Bandwidth (12.5KHz or 25KHz) Mute Settings P25 NAC codes Profile Name and Number (max 256 Profiles) Figure 14 Channels Panel The each channel in the menu is treated as a profile for the signal graph, as defined in the signals panel. A channel be dual mode by adding both FM and APCO P25 functions, in parallel, to the same signal graph. When editing a profile, certain options are not selectable until the function is added to the signal map. The availability of the following options in the profile table will depend on the existence ECLIPSE2 IPCommander User Manual 35 of the appropriate function block on the signal map. FM Modulator FM Demodulator Tone Encoder (CTCSS & DCS) Tone Decoder (CTCSS & DCS) P25 Modulator (APCO P25) P25 Demodulator (APCO P25) For example, placing the tone decoder block into the signal map will enable the Subaudio panel in RX profile. Each channel is effectively a stored profile. Each entry in the channel table has an associated channel number, a transmit frequency, a receive frequency and a reference profile number. To edit the channel name or frequencies double click the appropriate field, make any appropriate changes and click the Apply button. To make any channel active double click the leftmost column in the channel table and click the Apply button. A channel entry in the table will have a green icon displayed indicating that it is currently active. 7.1. Overview The Overview tab, within the channel panel, displays the profile number and name, channel bandwidth and CTCSS tones. Every entry in the table has separate RX and TX profiles. The Eclipse2 can store up to 256 Profiles and 256 Channel Numbers. 7.2. FM & P25 RX Profile Sets the channel bandwidth. Values are 12.5KHz or 25KHz. 7.3. FM & P25 TX Profile Configures the following fields:

Maximum Deviation Transmitter Hang Time from 0.1 to 99 seconds ECLIPSE2 IPCommander User Manual 36 Transmit Limit Timer from 0 to 999 minutes 7.4. RX Subaudio The RX Subaudio tab defines the CTCSS or DCS tone for the current profile. 7.5. TX Subaudio The TX Subaudio tab defines the following fields:

CTCSS or DCS tone. CTCSS Deviation DCS Deviation DCS Invert Enable No Tone Period Enable Reverse Tone Burst 7.6. RX Mute/RSSI The Mute/RSSI Tab stores the mute settings for the receiver. The mute state can be determined either by the signal strength in dBm or the carrier to noise ratio in dB. Typically, the RSSI Hysteresis will be set in the range 2-4dB, and both C/N and C/N Hysteresis will be set to zero. 7.7. RX P25 Conventional APCO P25 systems use a Network Access Code (NAC). The Rx profile (P25 Tab) allows user to specify whether the base station shall accept a P25 call with any NAC or with a user specified NAC, thus restricting radio network access. Three specific NAC codes are set aside for the following functions:

293 Default NAC F7E The receiver will unmute on any NAC F7F This will cause the transmitter to set its NAC from the received NAC. 7.8. TX P25 The TX C4FM modem can be configured to transmit a STD DEV or STD 1011 patterns for servicing and testing purposes. Deviation scale allows user to adjust the deviation in a range from 90% to 110% from the normal setting of 100%. ECLIPSE2 IPCommander User Manual 37 7.9. TX P25 The TX P25 tab allows the user to choose whether to repeat the incoming NAC or override with a user defined TX NAC code. 7.10. TX CWID The TX CWID tab allows the user to set the period between CWID identifiers, the speed of the Morse Code, the frequency of the CW tone used and the message being sent. The ID field is used to set the Morse code message to be transmitted. It can be up to 20 characters in length, and contain the characters A-Z, 0-9 and the punctuation characters shown in Table 1. Lower case letters will be converted to upper case. The Tone field sets the frequency of the tone used to transmit the Morse code, in units of hertz. The Morse Speed field controls the speed at which the Morse code is transmitted. It is in units of words per minute, where the word being transmitted is PARIS. The TX Interval field controls the period between each CWID identifier. It is in units of seconds, and may take a value up to 9999 seconds. A detailed description, of the operation of the CWID block, is in section 6.2.28. 7.11. Trace The Trace menu displays low-level internal software messages from the Reciter Module. These messages can be saved to a log file and used for diagnostic purposes. ECLIPSE2 IPCommander User Manual Figure 15 Trace Panel 38 ECLIPSE2 IPCommander User Manual 39 8. Calibration The Calibration Menu allows the audio codec, RF Exciter Power and Receiver RSSI values to be saved to the Reciter Module. Use the procedures in the Eclispe2 Technical Manual to calibrate the Reciter Module. 8.1. Codec calibration The Codec calibration stores a reference audio level for the Line In and Front Panel Microphone audio inputs. Figure 16 Codec Calibration 8.2. Output power calibration The Output Power calibration stores the user entered values measured from a Radio Test Set. It sets the relationship between the actual power level in the Eclipse 2 and the value, in units of watts, displayed by IP Commander.

Eclipse2 Technical Manual, 3-Aug-12 Page 5 of 17 Introduction The Eclipse2 series is a Base Station designed for Conventional Analogue FM and Conventional APCO P25 modes of operation. Internally, it is driven by software, allowing future firmware releases to track the development of radio standards and add new modes. Based on a DSP and RISC platform, the base station has a modular design, which provides extensive flexibility for users. For example, it may act as a standalone transmitter/receiver, cross-

band repeater, and more. The built-in Ethernet port allows remote monitoring and control of all operating parameters. Under software control, the centre-frequency can be arbitrarily tuned across a band, within the limits of the installed receiver and transmitter submodules. A range of available submodules allows The Eclipse2 system to cover most of the band from 66MHz to 941MHz. A typical base station or repeater system includes a Reciter (Receiver & Exciter); an RF power amplifier; and a switch mode or linear power supply. All the modules can be plugged into an RF Technology standard 19 inch wide, 4U high, rackframe. The Reciter can deliver enough RF output power to be useful as a point-to-point link, meaning an external power amplifier may not be required in some configurations. This allows up to six Reciters to be mounted into a single 19 inch rack. Features Specifications General Channel Spacing Reference Frequency Monitor speaker output:

This software is based on the Java platform and can be run under various operation systems on the host computer, it provides a number of useful facilities for the configuration and monitoring of the base station. The IP Commander software allows configuring of the base station (e.g. the channel frequency, output power, signal path, etc.) without hardware alignment, it also provides a simple means of calibrating the RF power, RSSI level, audio line levels. For more details of IP Commander software, please refer the document: RFT Doc No. 0305917801 (IP Commander User Manual). There are two interfaces which can be used for connecting a computer and the Reciter:

Eclipse2 Technical Manual, 3-Aug-12 Page 10 of 17 Connecting with Ethernet Ethernet is the interface of the base station, especially for remote monitoring and controlling via an IP Network. Each base station has a unique IP address, to connect, the host PC must be in the same subnet with the base station. Connecting with USB The front-panel USB connector can be also used for connecting to a computer, IP Commander Software loads a USB driver to recognize the base station. Technical Description The transceiver consists of three sub assemblies: Control Board, Interface board, and RF modules. Control Board The Control Board is a multi-layer, double side component mounted PCB assembly. The most important parts of the base station, such as CPU, DSP and digital IF receiver, are embedded in this master board, two 40-pin connectors on this board allows user inserting/removing it from the interface (main) board. The CPU (U1) is a single chip 32-bit RISC processor, it controls all the operating functions of the base station. The support chips include a 16Mbyte Flash (U9) and 64Mbyte SDRAM (U7, U8). The base station software and configuration databases are stored in the Flash memory. The system serial bus and GPIO of the RISC processor are connected to the system interface board via two 40-

pin connectors. The 10/100Mbps Ethernet Physical Layer single chip transceiver (U10) provides the interface between RISC processor and the Ethernet. A serial ATA cable is used for connecting between the Master board and System interface board. The DSP (U2) is a 32-bit fixed-point digital signal processor, which provides the base band processing including modulation, demodulation, RSSI/SINAD calculation, CTCSS encoding/decoding and audio processing of the base station. The DSP software is modularized, the modulator, demodulator, pre-emphasis, de-emphasis, filters and gain are individual modules, user can connect or disconnect any module by the Service Kit software for different applications. The DSP also controls the frequencies of the PLL chips within the RF modules. The digitized audio signal interfaced to the CODEC of the system interface board is via the DSP serial port. The digital IF receiver consists of an ADC (analogue to digital converter, U4) and a DDC (digital down converter, U3). The pre-filtered analogue IF signal from the receiver module is fed to ADC, converted to the digital IF and passed to the DDC via the parallel bus, the DDC mixes the incoming digital IF with the internal Numerically Controlled Oscillator (NCO) frequency signal to produce the 0Hz IF, the DDC also provides decimating and further filtering for the IF signal. The output from the DDC is in complex I/Q format, sent to the DSP for demodulating via the serial bus. Eclipse2 Technical Manual, 3-Aug-12 Page 11 of 17 The clock of ADC, DDC and DSP is derived from the system interface board. Interface (Main) board The Interface (Main) board provides the interfaces among the Processor (main) board, RF modules and external equipment. The function of the Interface board can be described as following sub sections. Audio signal processing External audio signals from/to the base station are processed in this section. The balanced audio input from RJ45 E/M Line connector or D25 system connector is passed, after line matching transformer (T1) coupling, to a Trans-conductance amplifier (U11), the gain of the amplifier is controlled by the RISC processor. The output of this amplification stage is then amplitude limited, attenuated and filtered before send to the channel 1 of the CODEC (U12). The CODEC encodes the analog audio to digital PCM signal send to the DSP via the serial bus. The Microphone input from front panel RJ45 connector is amplified by op-amplifier (U16), amplitude limited and attenuated then fed to the cannel 2 of the CODEC (U12). The CODEC encodes the analog audio to digital PCM signal send to the DSP via the serial bus. The AUX input signal from D25 system connector is DC coupled, filtered and amplitude limited by the op-amplifier (U16), then fed into a 16-bit ADC (U17) to convert to the digital signal. The digitized signal is send to the DSP via the serial bus. This AUX input is useful for low frequency

(down to 0Hz DC) signals, the DC offset of input signal is shifted by the bias circuit which is controlled by the RISC processor to give the maximum dynamic range for the ADC. The CODEC has two identical channels, the output of channel 1 is used for line output. PCM signal from the DSP is decoded to analog audio, and amplified, buffered by op-amplifier U10, coupling through the line matching transformer (T2), and sent to the RJ45 E/M Line connector and the D25 system connector. The channel 2 output of the CODEC is used for monitor speaker, PCM signal from the DSP is decoded to analog audio, amplified by a Trans-conductance amplifier (U11), this amplifier is used as the speaker volume control. The power amplifier (U13) provides additional power gain to drive the internal and external speaker. A 16-bit DAC (U14) converts the digital output from the DSP to analog signal, the signal is filtered and buffered by op-amplifier (U10), then sent to the D25 system connector. The amplifier is DC coupled, the DC offset can be set by the bias circuit which is controlled by the RISC processor. This output is useful for low frequency application such as sub-tone, and NRZ digital signals. I/O and Controls The RISC processor uses serial buses and GPIO to control the base station. A 10-bit 11-channel ADC (U7) senses the following signals and passes the data to the RISC processor via serial bus:

Channel 0:

Channel 1:

Channel 2:

The op-amplifiers (U4, U28) are used for converting DAC output to proper voltage which is required by the system hardware. The Interface board accepts both TTL PTT input and E/M signaling, the TTL PTT is buffered by Q4 and Q5, E/M signal is isolated by Opto-coupler U3 to system I/O level. The output of the RISC I/O logic is buffered by U1,Q1-Q3 for interfacing the external logic. The solid-state relay Opto-coupler is used to isolate the system I/O from E/M signal. A dual retriggerable monostable multivibrator (U5) in the circuit is functioned as a IRQ generator, it senses the changes of the Input logic and sends a narrow pulse to the RISC processor for trigging the processing IRQ. U31 is a USB to RS232 bridge which transfers the USB data between the front panel connector and the system serial bus. U9 is an transceiver which converts RS232 +/-15 logic from the rear panel to serial bus level. U30 is a bus switch to select one of above passing through to the RSIC processor. Header (H4) is used only for emergency system booting purpose, do not assert jumper into this header. Clock generator the 12.8MHz TCXO (X1) output is buffered (by U26) and divided by 4 (U29) to provides PLL reference frequency for exciter and receiver. The frequency doubler double 12.8MHz frequency to 25.6MHz to provide system clock for digital IF receiver. Voltage regulators

-12V The input power supply voltage is 13.8VDC, LDO (U19, U22) provides 12.5V (Imax = 1.5A) and 12V DC (Imax = 800mA) for TX and RX module. Switch mode DC-DC converter (U20) generates digital 3.3V DC rail (Imax=2A) for the Processor board and Interface board, then regulated to 3.15V analog DC rail by LDO (U21) for 3V analog circuits in the transceiver. The DC-DC converter (U23) provides 20V negative supply voltage for VCO bias amplifier (U4). Voltage regulator (U24) generates 12V DC supply analog circuits of the interface board. RF modules Eclipse2 Technical Manual, 3-Aug-12 Page 13 of 17 TX module The TX module can be divided into the VCO, PLL, PA and the Data storage section. The Voltage Controlled Oscillator (VCO) The Voltage Controlled Oscillator uses a junction FET (Q2) which oscillates at the required transmitter output frequency. Varactor diodes (D2, D9, D10, and D11) are used by the PLL and bias control circuits to keep the oscillator on the desired frequency. Transistor Q1 is used as an active filter to reduce the noise on the oscillator supply voltage. The VCO is keyed ON by the RISC processor through Q3, It is keyed ON when any of the PTT inputs are active or self-calibrations, but OFF at all other times. The VCO output is amplified by monolythic amplifier U4 before being fed to the PLL chip (U10). The Phase Locked Loop (PLL) The frequency reference for the PLL is from the Interface board via a 20pin connector. A fractional-N PLL synthesiser (U10) is used in the TX module, this fractional-N synthesiser provides very fine frequency resolution which enables the PLL used as a FM modulator by modulating the PLL data. The modulation data is provided by DSP via the serial bus. The phase detector output

(charge pump) signal of U10 is smoothed and filtered by the loop filter to form the tuning voltage for the VCO circuit. The Power Amplifier (PA) Amplifiers (U1, U2) increase the VCO output to a sufficient level to drive the power amplifier (U3). The output power level of the PA is controlled by RISC processor via bias pin of U3. The directional coupler (D3, D4) detects the forward and reverse power components, the detected voltages are then amplified by U7 and U8 to provide proportional dc levels to the RISC processor. The output from U3 is further filtered by the low pass filter to reduce higher order harmonics. U1, U2 and U3 are not switched on until the PLL has locked and had time to settle. This prevents any momentary off channel transmission when the transmitter is keyed. The Data Storage Each TX module has an EEPROM for storing the individual module information such as, TX module serial number, model name, frequency range, calibration data etc. This is allows user to simply replace the TX module in the transceiver without redo the alignment and calibration. The data is transferred between EEPROM and RISC processor via the serial bus. RX module The RX module can be divided into the Font-end Amplifier, LO, PLL, IF amplifier and the Data storage section. The Front-end Amplifier A two-pole voltage tuned filter (D6, D7, L18-20, L23 and L24) is used to limit the RF bandwidth prior to the RF amplifier transistor Q1. The tuning voltage is supplied by the RISC processor through the bias control. The circuit values are chosen so that the centre frequency tracks the VCO bias voltage. RF amplifier transistor Q5 is followed by a second two-pole voltage tuned filter (D4, D5, L7, L11, L14, L21 and L22) which provides additional image and spurious frequency rejection. The filter output is connected to the RF input port of the mixer MX1 via a 1.8dB pad. The Mixer MX1 is a level 13 double balanced diode ring mixer with excellent Intermodulation performance. It has a conversion loss of approximately 6 dB. The gain between the receiver input and the mixer input is approximately 10 dB so that the total gain between the antenna input and the IF input 3-

Eclipse2 Technical Manual, 3-Aug-12 Page 14 of 17 4dB. The network (C28, C74, L29, L15, L16 and R20) passes the IF frequency of 45 MHz and terminates the RF and LO components. The Local Oscillator (LO) The LO is a Voltage Controlled Oscillator (Q2) which oscillates at the required transmitter output frequency. Varactor diodes (D2, D9 - D11) are used by the PLL and bias control circuits to keep the oscillator on the desired frequency. Transistor Q1 is used as an active filter to reduce the noise on the oscillator supply voltage. Monolithic amplifiers U1, U2 and transistor Q6 amplify the VCO output to approximately +16dBm then feed to the mixer via a 3dB pad. The Phase Locked Loop (PLL) The frequency reference for the PLL is from the Interface board via a 20pin connector. A fractional-N PLL synthesiser (U10) is used in the RX module, PLL frequency PLL is set by DSP via the serial bus. The phase detector output (charge pump) signal of U10 is smoothed and filtered by the loop filter to form the tuning voltage for the VCO circuit. The IF Amplifier The first IF amplifier uses two parallel connected JFET transistors Q3 and Q4 to obtain 8-10 dB gain. The two transistors provide improved dynamic range and input matching over a single transistor. A 4-pole 45 MHz crystal filter (FIL1, FIL2) is used between the first and second IF amplifiers. The second IF amplifier (U3, U5) provides additional 35dB gain to drive the digital IF. A two pole crystal filter (FIL3) is used as an anti-alias filter of the digital IF. The Data Storage Each RX module has an EEPROM for storing the individual module information such as, TX module serial number, model name, frequency range, calibration data etc. This is allows user to simply replace the RX module in the transceiver without redo the alignment and calibration. The data is transferred between EEPROM and RISC processor via the serial bus. Field alignments As the TX and RX module is pre-tuned for the whole operational frequency range and level adjustment of signal path is done by software (local or remotely), there is no field alignment required for optimizing the performance. Specifications Description The transceiver is a digitized, software upgradable radio, The exciter and the receiver can be configured as base station, repeater or the stand-alone unit. For base station use, the exciter normally drives a high power external RF amplifier. It can also be used alone in lower power applications. The output power can be preset between 0.3 and its maximum. All necessary control and 600 ohm line interface circuitry is included. Channel Capacity Although most applications are single channel, it can be programmed for up to 256 channels (from CH0 to CH255). Each channel can have its own name, TX/RX frequencies and profiles. Sub Audio Signaling Full EIA CTCSS capability as well as nonstandard sub tones are built into the modules. The CTCSS tone can be programmed for each channel in their profiles. This means each channel can represent a unique TX/RX and tone frequency combination. Eclipse2 Technical Manual, 3-Aug-12 Page 15 of 17 Channel Programming The channel information is stored in Flash memory and can be programmed via the Ethernet, USB or RS232 interface using a Host PC and RF Technologys Service Kit software. Channel Selection Channel can be select by Service Kit or front panel buttons (if enabled). Physical Configuration The transceiver is designed to fit in a 19-inch rack mounted frame. The installed height is 4 RU

Eclipse2 Technical Manual, 3-Aug-12 Page 16 of 17 RF Exposure. This transmitter exciter constitutes a RF transmitting system that both the FCC and Industry Canada has established RF exposure requirements for. In order to comply with the RF exposure requirements of both countries the transmitting antenna must maintain a specific physical separation from all persons. The antennas for this device usually are mounted on outdoor permanent structures and the installer must see that the separation distance be maintained. The RF exposure report was written for one typical power output and antenna gain. If your situation is different than the one described your minimum separation distance will be different. RF exposure takes into account many different contributing factors some of which are: power output, system losses, coax cable losses, and antenna gain. For a typical installation of a 3 dBi antenna and 3 W UHF band (470-495 MHz) transmitter. Operated in a radio system were the average ratio of transmit to receive time is near 100% transmitting the separation distance would be 0.33 meters or approximately 1.5 feet. This separation distance also does not take into account any other transmitters that might be considered co-located at the same site. An RF exposure report was prepared for this transmitter and in it are the typical calculations on which the above is based. Eclipse2 Technical Manual, 3-Aug-12 Page 17 of 17
