The DRB-25 Modules will perform self-test diagnostics after power is applied. Visual indicators on the module front panels will convey the status of the DRB-25 to the Operator. If any of these visual indicators show an error or fault code, simple faultfinding procedures may identify the problem and suggest an immediate solution. If operational checks reveal a fault in DRB-25 equipment, it may be necessary to replace it. Removal of equipment is the reverse of the installation procedure described in Chapter 3. Any faulty items should be carefully packaged and sent to an authorized repair center. If faults are not corrected by substituting equipment at an operational level, contact the supplier or its representative. Additional connectors on the front and back panels of selected equipment allow maintenance personnel to access functions for system configuration, operational statistics and faultfinding. 4.2 SWITCHES There are two types of switches on the front panels of the DRB-25: power and reset switches. If an AC supply is used with the DRB-25, there is a master power supply switch on the rear of the unit which should be turned on first. The power switches on the front panel of the Power Supply Modules are switched on next. Recessed reset switches on the Transceiver, Controller and Interface Modules (optional) allow the equipment to be reset. Table 4-1 describes each reset switch and its function. Table 4-1 Reset Switches Equipment Reset function Interface Module Controller Module Transceiver Module APPLYING POWER Resets all modules (accessed from rear ) Resets all modules (accessed from front) Resets the Transceiver Module (accessed from front) 4.3 Perform the following final checks before applying power:

1. Check that the ground wires are connected to the DRB-25 primary ground from an external ground point. 2. Check that all equipment and connections are secure. 3. Ensure the power cable to the DRB-25 is plugged in securely and switch power on. AMX-MA-00654 Issue 0.02 (USA) 2 Installation and Operator Handbook Operating Instructions 4. Switch on each Power Supply Module Note that DC direct configurations have no power supplies or switches. 4.3.1 Initial Power-On Checklist Refer to Table 4-2 to verify that power indications are correct. Should displays or indicators suggest a fault condition, refer to 4.3.2 before proceeding. The DRB-25 performs a self test and warm-up routine at power-on. During this, the Controller display flashes while the Transceiver display remains blank. When the warm-up is complete, the Controller READY indicator illuminates and the display changes to an oscillating pattern. The Transceiver then tunes to its default channel and displays the channel number, and the unit is ready to operate. At normal temperatures the Controller takes approximately one minute to warm up, however at -30C warm-

up will take up to 10 minutes.

AMX-MA-00654 Issue 0.02 (USA) 6 Installation and Operator Handbook Operating Instructions 4.5 CONFIGURATION If all the external indications are that the DRB-25 is operational, proceed with the configuration process using the Transceiver Module Programmer application as described in Chapter 5. Once configuration has been completed, the DRB-25 can be tested in its intended system environment. Channels may be configured as fixed channels or scan channels as described in Chapter 5. 4.5.1 Fixed Channel Operation Fixed channels will operate according to all the parameters entered in the channel settings dialog box (see chapter 5). 4.5.2 Scan Channel Operation Scan channels may be set up to scan between up to eight channels. The first channel selected in the scan sequence will define the operating mode (local or remote basestation or repeater), station ID, timers, encryption, power output and source priority during all scanning. The DRB-25 will scan between the channel mode, spacing, talk group ID, receive configuration and transmit configuration of each selected channel. The DRB-25 will scan sequentially through the selected channels, with a maximum scan rate of 2 channels per second (500ms on each channel), unless a valid signal is detected on a channel. If a valid signal is detected then the DRB-25 will remain on that channel until the call is completed, then continue scanning. The scan channel can also be programmed with additional dwell times, such that the DRB-25 will remain on the channel for the specified dwell time after the completion of a call, to allow for a return call. 4.6 LOCAL OPERATION The DRB-25 may be operated locally by using a DTMF microphone and speaker connected to the front panel handset socket of the transceiver module. Each transceiver must have a separate speaker and microphone. 4.6.1 Monitoring Audio In single channel configurations a loudspeaker panel may be fitted to the unit to provide a speaker and volume control (refer to 3.5.4.6). Audio may be also monitored from the Transceiver Module via an external speaker connected to the front panel RJ45 audio connector. The speaker will monitor audio on the selected channel of the transceiver, with receive parameters as defined by the channel table entry in the Transceiver Module Programmer. In normal operation all traffic with a valid NAC (digital mode) or CTCSS/CDCSS (analog mode) will be routed to the speaker. When operating as a basestation the unit may be put into monitor mode by keying the sequence *5* on a DTMF microphone connected to the transceiver module audio connector. In monitor mode all traffic on the receive frequency will be routed to the speaker irrespective of NAC or CTCSS/CDCSS. The DTMF key sequence *5* will revert the basestation to normal squelch mode. Note : the DTMF key # will erase any preceding (incomplete) DTMF key sequence. AMX-MA-00654 Issue 0.02 (USA) 7 Installation and Operator Handbook Operating Instructions 4.6.2 Making Calls Calls may be sent from the DRB-25 using a microphone connected to the transceiver module front panel RJ45 audio connector. Calls will be broadcast with the transmit NAC and Talkgroup ID (digital mode) or transmit CTCSS/CDCSS (analog mode) of the transceivers current channel, as defined by the channel table entry in the Transceiver Module Programmer. 4.6.3 Changing Audio Volume If a loudspeaker panel is fitted, audio volume is controlled by the volume knob on the panel. If an external speaker is connected, audio volume may be controlled using a DTMF microphone connected to the transceiver module front panel RJ45 audio connector. The DTMF key sequence *2*nn* will set audio volume to level n between 00 (off) and 09 (full volume). Note : the DTMF key # will erase any preceding (incomplete) DTMF key sequence. 4.6.4 Changing Selected Channel:

The transceivers current channel may be changed using a DTMF microphone connected to the transceiver module front panel RJ45 audio connector. The DTMF key sequence *1*nnn* will change the transceiver to channel nnn. The selected channel will be displayed on the front panel of the transceiver module. Note : the DTMF key # will erase any preceding (incomplete) DTMF key sequence. 4.6.5 Squelch Adjustment The receiver squelch level may be set in analog mode using a DTMF microphone connected to the transceiver module front panel RJ45 audio connector. The DTMF key sequence *3*nn* will change the squelch level as follows:

*3*00* sets carrier squelch.

*3*nn* sets squelch level to nn dB SINAD where nn is between 06 and 20. Squelch hysteresis is 2dB. 4.7 REMOTE OPERATION The DRB-25 may be controlled remotely using any industry standard tone remote control console over two or four wire telephone lines using leased lines or dial up, provided the DRB-25 is fitted with the corresponding two or four wire line interface option. One line is used for each transceiver. To configure the DRB-25 for remote operation:

1. Connect the two or four wire line(s) to the RJ45 line socket on the interface module at the rear of the DRB-25. 2.

The DRB-25, shown in Figure 1-1 and Figure 1-2, is a compact, multi-mode transceiver package which provides users with one or two analog or APCO Project 25 digital radio channels. The small size and high level of flexibility of the DRB-25 make it an ideal solution for any organization starting out on the digital migration path. Figure 1-1 Front View - DRB-25 AMXMA00651 Issue 0.02 (USA) 2 Installation and Operator Handbook Introduction Figure 1-2 Rear View - DRB-25 The DRB-25 provides one or two independent radios in a single package. Each radio can be used as a base station or a repeater, and may be configured to support both APCO Project 25 compliant digital subscribers as well as providing backwards compatibility to analog users. This means that existing mobile radio equipment need not be immediately retired. Each radio may be configured to provide an analog interface (2 wire with loop or ground start or 4 wire with E & M signaling) to the public switched telephone network (PSTN), to a private branch exchange (PBX), or to existing tone based remote control units. The DRB-25 provides the key elements of an APCO Project 25 RF Sub-system including the air interface

(Um), interfaces for telephone and PBX interconnect (Et) and host data systems (Ed). Support for Ethernet based network management, digital consoles and the APCO Project 25 fixed station interface (Ef) will be available as software upgrades.

Compatible with Microwave Links using 4 Wire and E & M signaling. User friendly Windows configuration and diagnostic software for local or remote configuration. Self test diagnostic routines. 240/110 VAC or 12, 24 or 48 VDC versions. Available as a standard 19 rack mount sub-rack, as a desktop unit or housed in a secure floor mount cabinet. In addition, the DRB-25:

Enables a gradual migration from analog to digital terminals, or from one frequency band to another, communicating across-mode and across-bands while the migration is taking place. Provides link radio functions to other base stations or repeaters for geographically remote areas. Enables upgrade from a single-channel to dual-channel at low cost. Provides a low cost upgrade path from the dual-channel to a multi-channel base station. 1.2 PHYSICAL ARRANGEMENT 1.2.1 General The DRB-25 is a completely self-contained cabinet unit housing all the components necessary to support one

(single-channel) or two (dual-channel) radio configurations. The basic housing is provided with feet for desktop use and may optionally be supplied with mounting brackets for rack-mounting. Alternatively the entire unit may be installed in a secure cabinet. Integral to the housing are the system power supplies, fans and airflow control for cooling of modules and a common backplane into which the Transceiver, Controller and Interface Modules are plugged. A single-

channel DRB-25 requires one Controller Module and the following plug-in modules:

AMXMA00651 Issue 0.02 (USA) 4 Installation and Operator Handbook Introduction One Transceiver Module. One Power Amplifier Module. One Power Supply Module. One Interface Module (Optional - depending on external interfaces). A dual-channel DRB-25 requires one Controller Module and the following plug-in modules:

Two Transceiver Modules. Two Power Amplifier Modules. Two Power Supply Modules. One Interface Module (Optional - depending on external interfaces). A single-channel DRB-25 can be easily and inexpensively converted to a dual-channel DRB-25 by the installation of the additional modules. The DRB-25 may be configured for AC or DC power sources, or as AC power with DC revert in the case of AC power failure. A block diagram of a DRB-25 is shown in Figure 1-3.

The configuration options are summarized in Tables 1-1 to 1-3 Mode Of Use Single-channel Repeater Dual-channel Repeater Scanning Repeater Crossbanding Repeater Crossmoding Repeater Crossbanding and Crossmoding Repeater Table 1-1 DRB-25 Operational Configurations Description The DRB-25 is configured with a single Transceiver, PA and Power Supply. If a mobile radio makes a call on the Transceivers assigned frequency, the signal is repeated using the same format (analog or digital) used by the mobile. The DRB-25 is fitted with two Transceivers, PAs and Power Supply Modules. If a signal is received on the assigned frequencies of either of the Transceivers the signal is repeated in the same format in which it was received. Both Transceivers operate independently and two signals may be repeated simultaneously although not on the same frequency. The DRB-25 is configured as either a single or dual channel unit. Each transceiver is programmed with up to 8 channels which can be any mix of frequency and operating mode (analog/digital). The transceiver scans through the list of programmed channels until a valid signal is detected from a mobile when the signal is repeated using the same format (analog or digital) used by the mobile. The DRB-25 is fitted with two Transceivers and PA Modules which have operating frequencies in different bands. When a Transceiver receives a mobile call on its assigned frequency it repeats it using the same format, and passes the audio to the other Transceiver. The second Transceiver transmits the call on its assigned frequency in the user-programmed mode (analog FM or APCO Project 25). The DRB-25 is fitted with two Transceiver Modules which have operating frequencies in the same band. When a Transceiver receives a mobile call on its frequency it repeats it using the same format, and passes the audio to the other Transceiver. The second Transceiver transmits the call on its frequency in the user-programmed mode (analog FM or APCO Project 25). The DRB-25 is fitted with two Transceiver Modules which have operating frequencies in different bands. When a Transceiver receives a signal on its assigned frequency it repeats it using the same format, and passes the audio to the other Transceiver. The second Transceiver operating in a different band to the first transmits the call on its assigned frequency in the user-programmed mode (analog FM or APCO Project 25).

DTMF Microphone Tone Remote PSTN Microwave Description The DRB-25 operates as an standalone repeater (single or dual channel) and does not have any external wired voice connections. A single channel DRB-25 may be configured with a loudspeaker/handset panel in place of the second channel transceiver module and its associated power amplifier and power supply module. A DTMF microphone may be used to control the transceiver. Either one or two 2 wire or 4 wire + E & M connections are used to link the Transceiver Modules to industry standard tone remote units. Received audio is fed down the line and industry standard tone frequencies are used to control DRB-25 functions such as PTT and channel select. Existing analog tone remotes may be used with the DRB-25 operating in both analog and APCO Project 25 digital modes. Either one or two 2 wire or 4 wire + E & M connections are used to link the Transceiver Modules to the PSTN. Each connection can seize a line or grant a line in response to a PSTN request. Once a connection is established, monitor audio is fed down the line and tones from the remote end are used to control DRB-25 functions such as PTT and channel select. Either one or two 4 wire E & M connections are used to link the DRB-25 Transceivers to the outside world. The interface can be connected to a multiplexer of the microwave link. Table 1-3 DRB-25 Programming and Diagnostic Configuration Options Setup and Console Interconnection Programming using Transceiver Module Programmer (TMP) Diagnostics using DRB-25 Diagnostic Monitor (ZDM) Description A PC running TMP is connected to the front panel serial port of either transceiver module to upload programming information into the DRB-25. TMP may also be used remotely using a dial-up modem (future option). A PC running ZDM is connected to the front panel serial port of the Controller Module which enables both transceivers to be monitored and diagnostic checks to be run. The serial ports may also be used to connect the DRB-25 to a digital console (future option). ZDM may also be used remotely using a dial-up modem (future option).

AMX-MA-00657 Issue: 1.02 (USA) Page 5 of 25 Installation and Operator Handbook Programming and Configuration 5.2.8 Upgrading From TMP to DMR-25 The DMR-25 programmer has new features not available in the TMP programmer. If DMR-25 is used to upload channel table data which was programmed into a transceiver with TMP, the data elements describing the new features will be uninitialised, and may need manual editing afterward. By following the procedure below you can avoid the need for manual editing when upgrading to DMR-25. DMR-25 Upgrade procedure:

Step 1 - Transceivers with channel tables which were programmed with TMP should be read back with TMP and the BCF file saved to disk. You can skip this step if you already have a saved BCF file. Step 2 - Load the BCF file into DMR-25 using the File->Open menu items. When loading the file, the DMR-25 will set the new features to the default (disabled) state. The new features, in the Channel Settings dialog are: Channel Name, Squelch System, Squelch Group, CDCSS Invert, Autosense TX, Courtesy Tone Tail. See section 5.4.1. Step 3 - If you wish to use any of the new features, update their settings in the Channel Settings dialog . Particularly check the PTT Delay setting if you enable it, because the format has changed. Step 4 - The BCF file is now ready to be written back to the Transceiver, or saved to disk.

The channel name can be changed by overwriting the existing name in the window. The name is limited to 8 characters in length. Channel Number: The channel number is displayed in the Channel Number window. When a channel is created with the Add command, a sequential default channel number appears here and may be edited. The channel number of established channels may not be edited. Channel Type A channel can function as either a Fixed Channel or a Scan Channel. A Fixed Channel is a real channel used to transmit and receive voice messages. A Scan Channel holds a list of Fixed Channels through which the radio will scan in receive mode. The channel type is selected by clicking the Fixed or Scan radio button in the Channel Type box. Fixed Channel AMX-MA-00657 Issue: 1.02 (USA) Page 12 of 25 Installation and Operator Handbook Programming and Configuration Mode: Click as required to select the operating mode for the channel between basestation and repeater. In repeater mode, all valid inbound signals are repeated on the outbound channel. In base-

station mode, valid inbound signals are not repeated. Control: There are four functions/options that may be selected, Local control, Tone control, Line control and None. Local control: is via a DTMF microphone connected to the DMR-25 Transceiver Module audio connector elsewhere this is described as the front panel connector. DTMF tones can be used to configure/control the radio. Tone control: is via an industry standard tone remote control unit connected to the DMR-25 Interface Module line connector. Tone remote tones are used to control the radio. Line control: uses the rear panel audio port for control but disables tone remote signalling. When a 4-wire interface is used, control is achieved by E+M signalling. When a 2-wire interface is used, the radio is capable of making and receiving PSTN calls. In this mode call setup, dialing and cancellation is controlled by the subscriber radio using DTMF or Project 25 signalling. None: no control option is active. NOTE Control options are only available on DMR-25 Radios fitted with a controller module. Control options will be ignored by radios which are fitted with the Timing Module as a replacement for a Controller Card. Signal Type: Select the channel mode from the list of Analog, Project 25 and Autosense modes. Bandwidth: This setting determines the peak deviation of the transmitted signal, and the channel bandwidth used in the receiver. Select the required channel bandwidth from the list, to set wideband or narrowband analog or autosense operation. Wideband operation should be selected for use with analog systems employing 25 kHz or 30 kHz channel spacing. Narrowband operation should be selected for use with analog systems employing 12.5 kHz or 15 kHz channel spacing. Squelch System: Select the type of analog squelch required between CTCSS and CDCSS. Group Enable: When selected, the squelch system selection is disabled and a Squelch Group is required. Squelch Group: Select from a list of Squelch Groups, which are defined in Program/Squelch Groups see section 4.5 Squelch Groups. The Squelch System will determine which analog squelch is used in a squelch Group. Link Radio: Select to enable the Transceiver Module for cross-band and cross-mode operation. This selection will be disregarded by the transceiver if it is not licensed to support Link Radio. See Section 4.6 License Features. Enable Front Panel PTT: Select to permit transmissions to be made from the microphone connected to the DMR-25 Transceiver Module Front Panel audio connector. NOTE AMX-MA-00657 Issue: 1.02 (USA) Page 13 of 25 Installation and Operator Handbook Programming and Configuration Link Radio cannot be selected when Enable Front Panel PTT is enabled and vice-versa. Half Duplex: When half-duplex mode is selected, the receiver is disabled when transmitting and vice-versa. Half-duplex operation is only available in base-station mode. Receive/Transmit Configuration Freq (MHz): Enter the receive and transmit frequency for the selected channel. Note that the VHF radio frequencies can be set to 1Hz precision. However for the UHF radio, entered frequencies are internally rounded to a multiple of 5.0 kHz or 6.25 kHz (whichever is nearer) regardless of what is displayed or entered in the frequency dialog. When the DMR is operated in full duplex (simultaneous reception and transmission) isolation is required between the receive and transmit signals to ensure that the receiver is not de-sensed by the transmitter. The isolation is generally provided by a separate antenna or external RF combining network. Table 5-2 and Table 5-3 show the minimum and recommended isolation levels for VHF and UHF-Lo respectively.

For Project 25 / Autosense operation select the NAC as required, using hexadecimal (Hex) notation. Receive and transmit NAC may be set independently, or the transmit NAC may be set to be the same as the received NAC (Same as Rx). If analog channel mode is selected then these boxes will be disabled. Click on the Up/Down Arrows to increase/decrease the current NAC value. AMX-MA-00657 Issue: 1.02 (USA) Page 14 of 25 Installation and Operator Handbook Programming and Configuration The DMR radio can be programmed to un-mute on any NAC by entering the NAC values 0xF7E and 0xF7F as defined in the Project 25 suite of standards. CxCSS: Receive and transmit CxCSS may be set independently or the transmit CxCSS may be set to be the same as the received CxCSS (Same as Rx). If APCO 25 channel mode is selected then this box will be disabled. Click on the Up/Down Arrows to increase/decrease the current CxCSS value. CDCSS Invert: Select to invert the CDCSS encoding string pattern for both receive and transmit. Autosense TX: Selects the Transmit type (Analog or Digital) when a PTT from the front panel microphone or rear panel 4w/2w interface has been asserted on a channel whose signal type has been programmed as "Autosense". Encryption Algorithm ID: The DMR-25 Programmer currently supports clear transmission and DES-OFB algorithm. Key ID: The Key ID may be a number between 0x0000 and 0xffff. See Section 4.4 Encryption Settings for details. Timers PTT Tail (sec): Enter the amount of time the DMR continues to transmit a carrier signal after the Press To Talk is released, or click on the up/down arrows to raise or lower the Tail time in 0.1 second increments to a maximum of 9.9 seconds. PTT Delay (msec): (Applicable to Base-station Mode only) Enter the amount of time the Tx/Rx changeover relay is allowed to stabilize before RF power is applied, or click on the up/down arrows to raise or lower the Delay time in 1 millisecond increments to a maximum of 99ms. Set to zero if no changeover relay is used. PTT Timeout (sec): Enter the maximum duration of continuous transmission in seconds, or click on the up/down arrows to raise or lower the Timeout in 1 second increments to a maximum of 255 seconds. If no transmission length timer is required, set to zero. Courtesy Tone Courtesy tone is only applicable in repeater mode. Tail (sec): Enter the desired duration of the courtesy tone to follow analogue voice transmissions initiated from the front panel microphone or rear panel 2w/4w interface, or click on the up/down arrows to raise or lower the Tail time in 10 millisecond increments to a maximum of 9.99s. Tone (Hz): There are four options available, None, 400Hz, 1000Hz and 2500Hz. Reverse Burst: Reverse Burst is a feature designed to minimise the squelch crash at the end on an analogue transmission. If the reverse burst check box is selected in an analogue transmit mode then at the end of a transmission the CTCSS tone phase will be inverted for CTCSS channels or the CDCSS "turn-off" signal will be transmitted for CDCSS channels as described in TIA/EIA 603. When this box is selected, the Courtesy Tone tail setting determines the burst length, and Tone AMX-MA-00657 Issue: 1.02 (USA) Page 15 of 25 Installation and Operator Handbook Programming and Configuration setting is ignored. The tail time should be selected to optimise the performance of the particular analog mobile used in a system. General Talk Group ID: Select or enter the Talk Group ID for Project 25 transmissions from the DMR in basestation mode. Unit ID: Select Unit ID for the Base-station Unit. Power (Watts): Enter the transmit output power for the channel or click on the up/down arrows to raise or lower the output power in 1 W increments. Because internal communication with the PA is slow, around 30 seconds will elapse after radio startup before this setting becomes active. During those 30 seconds, the transmitter, if keyed, will transmit at full power. Scan Channels A scan channel consists of two or more fixed channels. The DMR-25 will step through the list of fixed channels until it finds one with a valid receive signal. The Channel Settings Dialog Box displays a list of fixed channels with their dwell times. Use the Add, Edit and Delete buttons to manage this list. Add: Adds a reference channel to the selected scan channel list using the Configure Scan Channel Reference Dialog Box shown in Figure 5-7. Select a fixed channel in the Reference Channel field and nominate a Dwell Time. Dwell Time is the period, in seconds, for which the DMR will monitor a particular reference channel given ceased activity on that channel. The selected reference channel is then added to the scan channel when the OK button is clicked or discarded if the Cancel button is clicked. Edit: Changes the parameters of a preconfigured fixed channel. Delete: Deletes the highlighted reference channel from the Scan Channel list.

Use the Installation Instructions in conjunction with the configuration checklist for the specific system being installed. 3.2 SAFETY PRECAUTIONS Observe standard safety procedures for the handling of electronic equipment:

WARNING FOLLOW CORRECT LIFTING PROCEDURES FOR HEAVY ELECTRONIC EQUIPMENT. ATTE NTION OB SERVE P RE CA UTI ONS F OR HANDLING ELE CTROSTATIC S ENSITI VE DEV ICES When removing or handling cards, use an anti-static wrist strap connected to ground and always place the card on an anti-static mat Handle modules by their edges and do not touch components or connectors. Avoid placing the DRB-25 near any source of excessive heat Avoid placing the DRB-25 near a naked flame Avoid placing the DRB-25 in a wet or damp location Do not subject the DRB-25 to severe mechanical shock AMXMA00653 Issue 0.02 (USA) 2 Installation and Operator Handbook Installation Instructions 3.3 SITE REQUIREMENTS Before installing the DRB-25 at the operating site, the following details regarding desk or floor space, rack clearance and lightning protection should be considered. 3.3.1 Desk/Floor Space or Rack Mounting Considerations The DRB-25 is 19 inches (483 mm) wide (standard 19 inch rack mountable), 14 inches (355 mm) high, 17.4 inches (440 mm) deep, and weighs 58 lb (26 kg) for a single radio configuration, or 81 lb (37 kg) for a dual radio configuration. When mounting the DRB-25 Cabinet:

Ensure that the DRB-25 is securely mounted. Ensure that the DRB-25 air vents are clear of obstructions. Provide sufficient space on all sides to of the DRB-25 to allow adequate access to the equipment and cables. Ensure that there is adequate space for entry of external cables (antenna and AC power cables) at the rear of the unit without the need for small radius bends. 3.3.2 Lightning Protection To minimize damage to equipment, or injury to maintainers, a complete system of lightning protection and grounding connections should be installed. The following points should be considered:

All down conductors, bonding interconnections, ground rings and radial tapes should be un-insulated solid copper tape at least 25 x 3 mm in cross section. All connection clamps and supports should be protected by non-reactive paste or tape. The use of gas lightning arresters or metal oxide varistors is recommended on line interfaces, including antenna cables. Protected test points should be included where appropriate and sacrificial grounding lugs should be clearly marked and accessible for periodic inspection and replacement if necessary. Use a large copper strap to take outer cable casings to a central ground bonding point. Antenna support structures, whether on the ground or on a building, should be connected to an o ring arrangement (or equivalent) via sacrificial ground lugs. A ground ring consists of copper tape with driver ground electrodes or radial tapes around the base of the structure (as close to it as possible), buried approximately 24 inches (0.6 m), where soil conditions allow. The main building and any other metalwork structures within 3m should be connected to a ground ring. AMXMA00653 Issue 0.02 (USA) 3 Installation and Operator Handbook Installation Instructions 3.4 DELIVERY AND UNPACKING The DRB-25 cabinet and supporting modules are packed and transported in customized packages which conform to best commercial practices for transportation and protection of electronic assemblies. The DRB-25 cabinet is delivered complete, requiring only the fitting of the plug in modules. In addition to the DRB-25 cabinet, the Modules which may be supplied in separate packages are:

One or two Power Supply Modules. One or two Power Amplifier Modules. One or two Transceiver Modules. Controller Module. Interface Module. In addition a programming kit may be provided, including a programming disk and interface cable. Before unpacking, examine the packages for evidence of external damage, water ingress or vermin activity which may have occurred during transportation. Examine the delivery docket or installation check list to confirm that the correct items for the intended DRB-

25 configuration has been delivered. Notify the supplier or its agent immediately if any discrepancy is noted. Unpack the DRB-25 as follows:

Carefully remove the DRB-25 cabinet from its packaging and relocate to a convenient level work surface. Remove all protective wrapping and inspect the cabinet for signs of damage or loose parts. Notify the supplier or its agent immediately if any is noted. Remove each of the modules in turn from their packages, unwrap and inspect as for the cabinet. Notify the supplier or its agent immediately if any damage or loose parts are noted. 3.5 INSTALLATION Take care to align each module correctly into its guide rails. Ensure that the module is correctly mated into the backplane of the DRB-25 and the connectors are firmly seated. Failure to do so may result in damage to the module or DRB-25 system. AMXMA00653 Issue 0.02 (USA) 4 Installation and Operator Handbook Installation Instructions 3.5.1 Tools Required The following tools should be on hand during installation:

Flat-bladed screwdrivers (small, medium and large). Cross-recessed (Phillips) screwdriver (large and medium). Cable ties and cutters. 9/32 inch (7 mm) hexagonal nut driver. Multimeter with pointed probes for continuity and DC voltage measurements. 3.5.2 Installing the DRB-25 Cabinet If the DRB-25 is to be desk mounted then screw the supplied feet to the four threaded inserts on the underside of the case and position the case as required.

Fix the DRB-25 in place by locating the two studs at the rear of the case through the hole in each bracket, and secure using the nuts supplied. Set the DRB-25s Identity (Box ID) and fit the modules as described in the following sections. AMXMA00653 Issue 0.02 (USA) 5 Installation and Operator Handbook Installation Instructions Figure 3-1 DRB-25 Rack Mounting Arrangement 3.5.3 Configuring DRB-25 Identity (Box ID) An 8-way DIP switch on the backplane adjacent to Transceiver 2 enables a Box ID to be set for each DRB-25. The switch is accessed from the front of the unit with the modules removed. A total of 256 identities are available. The Box ID is used by each Transceiver to determine its default settings on power-up. Transceiver modules can be programmed with up to 512 operating channels, and the default operating channel for each Transceiver is determined by the DRB-25 Box ID as detailed in Appendix A Table A-1. DRB-25 Box ID settings may be defined in a plan that covers all DRB-25 units in the network. The Box ID is also used by the Controller Module for network management purposes to enable it to identify itself within a network. The default factory setting is a box identity of zero. To set the DIP switches:

1. LOCATE the DIP switch on the upper right of the backplane, through the front of the DRB-25 case without the plug in modules fitted. AMXMA00653 Issue 0.02 (USA) 6 Installation and Operator Handbook Installation Instructions 2. 3. Using a screwdriver or pen, set the eight sections of the DIP switch to the desired Box ID, according to and the intended DRB-25 Box numbering plan. The Switch 1 (LSB) is the top switch; Switch 8 (MSB) is the lower switch. OFF is to the left, ON is to the right. 3.5.4 Installing the Modules Refer to the following figures (Figure 3-2, Figure 3-3 and Figure 3-4) to identify the correct position for each module within the DRB-25 cabinet.

The DRB-25 chassis and its component modules are described in the following paragraphs. 2.2 POWER SOURCE OPTIONS 2.2.1 AC Power Supply The DRB-25 may be powered from the 240 or 110 V AC power supply via one or two Power Supply Modules. Figure 2-1 shows the power distribution of an AC powered DRB-25. 12V DC Standby Power 110/240 V AC Supply Switch Power Supply Module 1 Fans System PSU 7 V 12 V Power Amplifier 1 Transceiver Module 1 Controller & Interface Modules Option for Second Channel Transceiver Module 2 Power Supply Module 2 Power Amplifier 2 Figure 2-1 Power Distribution of an AC powered DRB-25 2.2.2 DC Power Supply The DRB-25 may be powered from 12 or 24 or 48 V DC power supplies via one or two DC/DC Power Supply Modules. Alternatively, the DRB-25 may be powered directly from DC power sources as follows:

12 V DC to 13.8 V DC (for 60 watt Power Amplifier Modules). 24 V DC to 28 V DC (for 125 watt Power Amplifier Modules). Note that the RF output power of the DRB-25 is derated by 3 dB if the DC voltage is at the low end of the range (i.e. at 12 or 24 V DC). When operating from a direct DC power source the Power Supply Modules are replaced with blank panels.

The DC revert options are:

12 V DC to 13.8 V DC (for 60 watt Power Amplifier Modules). 24 V DC to 28 V DC (for 125 watt Power Amplifier Modules). When using DC revert the RF output power of the DRB-25 is derated by 3dB if the DC voltage is at the low end of the range (i.e. At 12 or 24 V DC). When operating from a direct DC power source the Power Supply Modules are replaced with blank panels. AC powered with 48 V DC revert is also available using external power supplies, however, where a 48 V DC battery backed supply is available it is generally preferable to use this as the main power source for the DRB-

25. 2.2.4 Reference Oscillator Backup Power The DRB-25 has provision for a user to connect a 12 V DC backup supply to keep the system reference oscillator oven at its operating temperature in the event of a brief primary power failure. An interface module connector acts as the connection point for the keep-alive power. If the backup supply is not used, any interruption to the primary supply requires a start-up cycle of up to ten minutes in which the reference oscillator heats up. AMXMA00652 Issue 0.02 (USA) 3 Installation and Operator Handbook Equipment Description 2.3 PLUG-IN MODULES The DRB-25 has the following types of plug-in Modules:

Transceiver Module. Controller Module. Power Amplifier Module. Interface Module. Power Supply Module. 2.3.1 Transceiver Module The Transceiver Module (TM) provides full duplex radio operation for analog and digital modulation schemes. Each module consists of an RF card for receive and transmit and a daughter board for digital signal processing. Modules are standard half-Eurocard layout measuring 10.5 inches (6 Rack Units) high by 10 inches (250 mm) deep. The Transceiver Modules plug into a common backplane with the Controller Module, providing seamless transfer and switching of traffic and control data. Transceiver Modules are specific to frequency bands and are available for frequency bands; VHF (136 to 174 MHz), and UHF (low) (400 to 470 MHz). Each Transceiver module may be programmed with up to 512 channels. Transceiver Modules of different bands are interchangeable provided the associated Power Amplifier is also changed. The Transceiver Module is powered by 12 V and 7 V supplies from the System Power Supply within the case of the DRB-25. Two RJ style connectors are provided on the module front panel. The upper connector (RJ11) provides a standard RS-232 serial interface which allows maintenance staff to program and configure the module using the Transceiver Module Programmer application software from an external PC. The lower (RJ45) connector provides an audio interface for the connection of a speaker, microphone or handset. Internally to the DRB-25 the Transceiver Module provides two connections to its associated power amplifier;

the RF output and a serial data link for control and communication between the two modules. Figure 2-3 shows the front panel controls, indicators and connectors and Table 2-1 lists the control and indicator functions. AMXMA00652 Issue 0.02 (USA) 4 Installation and Operator Handbook Equipment Description Figure 2-3 Transceiver Module Front Panel The Transceiver Module also provides interfaces to the internal backplane for audio, data and control. The Transceiver Module also provides an audio output interface for connection to a front panel speake when configured as a single channel system with optional front panel speake module.

Illuminated when a carrier has been detected on the receive frequency. If this indicator is ON but the SQUELCH indicator is OFF then an invalid signal has been received. Illuminated when the Transceiver Module is receiving power from the power supply. 2.3.2 Controller Module The Controller Module (CM) provides central control functions for the DRB-25 and high-stability timing for all radio elements. One Controller Module is required for each DRB-25 system. The module is a standard half-Eurocard plugged into a common backplane with the Transceiver Modules, providing seamless transfer and switching of traffic and control data. The Controller Module contains a 10 MHz oven-controlled reference oscillator from which all system timing is derived. The Transceiver Modules are inhibited from transmitting if the reference clock fails. Since the oven takes up to 10 minutes to reach its operating temperature and achieve the required stability provision is made for the connection of an external oven supply (12 V DC) which can keep the oven at the required temperature during power outages. It is also possible to supply an external 10 MHz reference directly to the Controller Module which is then used instead of the internal reference oscillator. The DRB-25 has six general-purpose inputs and outputs (provided on the Interface Module). These can be programmed to be alarm inputs for functions such as site alarms, AC power failure alarms etc. The Controller Module monitors all internal alarms generated by Transceiver Modules, Power Amplifier Modules and Power Supply Modules. The Controller Module also monitors the general-purpose inputs and can be programmed to activate a single general-purpose output or remotely interrogated to determine the cause of the alarm. AMXMA00652 Issue 0.02 (USA) 6 Installation and Operator Handbook Equipment Description Figure 2-4 shows the front panel controls, indicators and connectors and Table 2-2 lists the control and indicator functions. Figure 2-4 Controller Module Front Panel There is a RESET switch, nine indicators and one RJ11 connector on the front panel of the Controller Module. The RJ11 connector provides a standard RS 232 serial interface which allows maintenance technicians to program and configure the module using the programmer and to monitor radio functions with a computer.

(Green LED) 2.3.3 Power Amplifier Module The Power Amplifier Module (PAM) is a six Rack Units high plug-in module. One Power Amplifier Module is required for each Transceiver Module. Power Amplifier Modules are specific to frequency bands and are available for the same frequency bands as the Transceiver Modules. Power Amplifier Modules are available in 60 W (VHF) and 125 W (VHF and UHF) versions. The 60 W VHF version is for systems using analog FM and digital C4FM modulation schemes, and outputs up to 60 W between 136 MHz and 160 MHz and up to 50 W between 160 MHz and 174 MHz. 125 W Power Amplifier Modules support analog FM and digital C4FM. Each Power Amplifier Module has an on-board Microcontroller which supervises its operation and reports alarms via a control link to the associated radios. Power output is adjustable over a 10 dB range in increments of less than 1 dB. UHF Power Amplifier Modules can be fitted with optional circulators. Each Power Amplifier Module is powered by its associated Power Supply Module. The 60 W model operates from a 12 V Power Supply Module while 125 W models operate from 24 V. All Power Amplifier Modules for a given band are interchangeable provided that the Power Supply Module is changed if a 60 W Power Amplifier Module is replaced by a 125 W Power Amplifier Module. Figure 2-5 shows the front panel layout. AMXMA00652 Issue 0.02 (USA) 8 Installation and Operator Handbook Equipment Description Figure 2-5 Power Amplifier Module Front Panel The Power Amplifier Module has two connectors. The N-type connector is the Power Amplifier output connector, and the D connector contains RF input, DC power, and serial communications lines. 2.3.4 Power Supply Module The Power Supply Module provides the system power supply and one Power Amplifier Module with DC power derived from the 240 or 110 V AC power and is available in two versions depending on the Power Amplifier Module being used:

240/110 V AC to 12 V DC for 60 W Power Amplifier Modules. 240/110 V AC to 24 V DC for 125 W Power Amplifier Modules. AMXMA00652 Issue 0.02 (USA) 9 Installation and Operator Handbook Equipment Description The inputs of both 240/110 V power supplies are fuse-protected and the outputs are over-current protected. They have dry contact (relay contacts) alarm outputs which close when the unit is operating correctly and open in the event of a malfunction.

DC input for E & M signaling The general-purpose digital I/O provides six configurable inputs and outputs. Two of the output lines may be configured by jumper selection in the Interface Card to provide to drive 12 volt antenna relays for each of the transceivers. All other outputs, and these two when not configured as antenna drivers, provide optically-isolated contact closures which can be used to control other equipment. The six inputs are also optically isolated. With an input of 5v to 10v they are sensed as active (on), when open circuited, they are sensed as inactive (off). The first two inputs are used to disable the transmitter during test. The general purpose input and output lines, apart from the antenna relay outputs and transmit disable inputs, are unused in the present software release. In future releases user-configurability will be available. AMXMA00652 Issue 0.02 (USA) 12
