Configuring CAN Connections with Multiple Host Units9 EMS COMPUTER CONNECTIONThe service interface connection between the HU and the EMS computer is supported by asingle DB-9 female connector. The service connector provides an RS-232 DTE interface. Athree meter long straight-through RS-232 interface cable is available (accessory) for connectingthe EMS computer to the HU. Use the following procedure to install the service interface cable: 1. Connect one end of the service interface cable (accessory) to the SERVICE port as shownin Figure 3-11. 2. Route the service interface cable to the EMS computer and connect the free end of thecable to the computer’s RS-232 DCE port. Refer to the user manual provided with thecomputer to locate and configure the specified port. Figure 3-11.

A category 3 or 5 cable is typically used toconnect the HU to the external alarm system. Use the following procedure to install the alarmwiring and connect it to the HU: 1. Obtain the required length of category 3 or 5 cable. 2. Route the cable between the HU and the external alarm system (if not already routed) andthen cut to the required length. Allow sufficient slack for dressing and organizing the cableat the HU. 3. Strip back the outer cable sheath and insulation to expose the wires at both ends of thecable and strip back 0.2 inches (5 mm) of insulation from each wire. 4. Connect the Major alarm wire pair to the MAJOR COM/NC or MAJOR COM/NOterminals (whichever is required by the external alarm system) on the HU alarm terminalconnector (supplied with HU) as shown in Figure 3-12. Figure 3-12. External Alarm System Connections5. Connect the Minor alarm wire pair to the MINOR COM/NC or MINOR COM/NOterminals (whichever is required by the external alarm system) on the HU alarm terminalconnector (see Figure 3-12). 18830-AALARMCONNECTORMAJOR ALARM WIRESMINOR ALARM WIRESNOCOMNCNO COMNC

Connect the Major and Minor alarm wire pairs to the appropriate terminals on the externalalarm system. 7. Dress and secure cable per standard industry practice. 11 DC POWER CONNECTIONSThe HU is powered by ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The power is fed tothe HU through a screw-down type terminal strip located on the rear side of the unit. Power tothe HU must be supplied through a fuse panel such as the 20 position PowerWorx GMT FusePanel (available separately) and the power must be protected with a 3 Amp GMT fuse. Use thefollowing procedure to install the power wiring: 1. Obtain one pair of #18 AWG (1.00 mm) red and black insulated copper wire for use as thepower wiring. 2. Terminate one end of each wire with a fork terminal as shown in Figure 3-13. Figure 3-13. DC Power Connections3. Connect the power wires to the power terminal strip at the rear of the HU. 4. Route the free ends of the wires to the fuse panel and locate the terminals that will be usedfor the power feed. Refer to the user manual provided with the fuse panel for specificinformation. 18831-AFORKTERMINALS #18 AWG(1.0 mm)COPPERWIRE+ (RED) – (BLACK)

This process assumes that the various units have beeninstalled in accordance with the system design plan. 1.1 Tools and MaterialsThe following tools and materials are required in order to complete the procedures in thissection: • Portable spectrum analyzer or RF power meter• AC/DC voltmeter• External attenuators (if specified in system design plan)• PC-type computer with Digivance Element Management System (EMS) Version 2.0software installed• Straight-through RS-232 DB-9 interface cable (ADC part # 1192835)• Handset• Pencil or pen• Writing padContent Page
ADCP-75-159 • Issue 1 • August 2003 • Section 4: OperationPage 4-2© 2003, ADC Telecommunications, Inc.1.2 Readiness CheckBefore starting the turn-up process, inspect the complete Digivance system to verify that allcomponents of the system are ready to be powered-up. This will ensure that no units of thesystem will be damaged during turn-up and that all existing systems will continue to functionproperly. 1.2.1 Host Unit Installation ChecksComplete the following checks at the HU prior to starting the turn-up process: 1. Verify that the ON/OFF switch on the HU is in the OFF position (press O). 2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU. 3. Using a DC voltmeter, verify that the DC voltage level at the HU power terminals isbetween ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The DC power provided tothe HU can be either polarity.4. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured. 1.2.2 Remote Unit Installation ChecksComplete the following checks at the RU prior to starting the turn-up process: 1. Verify that the ON/OFF switch on the STM is in the OFF position (press O). 2. Verify that the MUTE/NORM/RESET switch on the LPA in the MUTE position. 3. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power tothe RU. 4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110and 120 VAC (for 120 VAC powered systems) or between 220 and 240 VAC (for 240 VACpowered systems). 5. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured. 2 TURN-UP SYSTEM AND VERIFY OPERATIONThe process of turning-up the system and verifying operation involves powering up the varioussystem components, verifying that the LED indicators show normal operation, setting the sitenumber and name, adjusting the RF signal levels, and adjusting the path delay.
ADCP-75-159 • Issue 1 • August 2003 • Section 4: OperationPage 4-3© 2003, ADC Telecommunications, Inc.2.1 Turn-Up ProcedureEach Digivance system should be turned-up separately before being networked together withmultiple systems through the CAN interface. Use the following procedure to turn-up eachDigivance system: 1. Temporarily disconnect the external alarm system or notify the alarm system provider thattesting is in progress. 2. If the HU is networked together with multiple HU’s, temporarily disconnect the CAN cablesfrom the NET IN and NET OUT ports of the HU. 3. Determine if the forward path composite input signal level at the Host Unit FORWARD RF INport is appropriate for the required RF output signal level and adjust by installing an externalattenuator if necessary. Refer to Section 2.3 for the calculation and adjustment procedure. 4. Connect the EMS computer (if not already connected) to the SERVICE connector on theHU or STM front panel. If necessary, a separate laptop computer loaded with the EMSVersion 2.0 software can be temporarily connected and used to initially configure thesystem. 5. Place the ON/OFF switch on the HU in the ON position (press I). 6. Make sure the switch on the LPA is in the MUTE position and then place the ON/OFFswitch on the STM in the ON position (press I). 7. Wait 6 to 8 seconds for the HU and the RU modules to initialize and then observe the LEDindicators on the HU, STM and LPA. Refer to Section 5 for the troubleshootingprocedures if the indicators do not respond as specified. 8. Start up the EMS Version 2.0 software program. The EMS main window will open asshown in Figure 4-1. Note: The EMS software should be installed on a PC-type computerand the PC’s COM port should be configured to interface with the HU. For informationabout installing the EMS software and configuring the PC’s COM port, refer to theDigivance Element Management System Software User Manual (ADCP-75-125). Note: By default, all HU’s and RU’s are programmed with the same site number andname. This can cause problems for the EMS if multiple HU’s with the same site numberand site name are networked together through the CAN interface. It is therefore necessaryto temporarily disconnect the CAN interface cables from the HU when configuring thesystem for operation until a unique site number and name can be assigned.
