9 EMS COMPUTER CONNECTION
The service interface connection between the HU and the EMS computer is supported by a
single DB-9 female connector. The service connector provides an RS-232 DTE interface. A
three meter long straight-through RS-232 interface cable is available (accessory) for connecting
the 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 shown
in Figure 3-11.
2. Route the service interface cable to the EMS computer and connect the free end of the
cable to the computer’s RS-232 DCE port. Refer to the user manual provided with the
computer to locate and configure the specified port.

10 EXTERNAL ALARM SYSTEM CONNECTIONS
The alarm interface between the HU and an external alarm system is supported by a six-terminal
plug (with screw-type terminals) that connects to a receptacle mounted on the HU rear panel.
The terminal plug provides connections to normally open (NO) and normally closed (NC) dry
type alarm contacts for both major and minor alarms. A category 3 or 5 cable is typically used to
connect the HU to the external alarm system. Use the following procedure to install the alarm
wiring 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) and
then cut to the required length. Allow sufficient slack for dressing and organizing the cable
at the HU.
3. Strip back the outer cable sheath and insulation to expose the wires at both ends of the
cable 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/NO
terminals (whichever is required by the external alarm system) on the HU alarm terminal
connector (supplied with HU) as shown in Figure 3-12.
Figure 3-12. External Alarm System Connections
5. Connect the Minor alarm wire pair to the MINOR COM/NC or MINOR COM/NO
terminals (whichever is required by the external alarm system) on the HU alarm terminal
connector (see Figure 3-12).

6. Connect the Major and Minor alarm wire pairs to the appropriate terminals on the external
alarm system.
7. Dress and secure cable per standard industry practice.
11 DC POWER CONNECTIONS
The HU is powered by ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The power is fed to
the HU through a screw-down type terminal strip located on the rear side of the unit. Power to
the HU must be supplied through a fuse panel such as the 20 position PowerWorx GMT Fuse
Panel (available separately) and the power must be protected with a 3 Amp GMT fuse. Use the
following 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 the
power wiring.
2. Terminate one end of each wire with a fork terminal as shown in Figure 3-13.
Figure 3-13. DC Power Connections
3. 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 used
for the power feed. Refer to the user manual provided with the fuse panel for specific
information.

1 BEFORE STARTING OPERATION
This section provides guidelines for turning-up the Digivance system, verifying that all units are
operating properly, testing to ensure that all performance requirements are satisfied, and
correcting any installation problems. This process assumes that the various units have been
installed in accordance with the system design plan.
1.1 Tools and Materials
The following tools and materials are required in order to complete the procedures in this
section:
• 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 2.0
software installed
• Straight-through RS-232 DB-9 interface cable (ADC part # 1192835)
• Handset
• Pencil or pen
• Writing pad

1.2 Readiness Check
Before starting the turn-up process, inspect the complete Digivance system to verify that all
components of the system are ready to be powered-up. This will ensure that no units of the
system will be damaged during turn-up and that all existing systems will continue to function
properly.
1.2.1 Host Unit Installation Checks
Complete 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 is
between ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The DC power provided to
the HU can be either polarity.
4. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.
1.2.2 Remote Unit Installation Checks
Complete 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 to
the RU.
4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110
and 120 VAC (for 120 VAC powered systems) or between 220 and 240 VAC (for 240 VAC
powered systems).
5. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.
2 TURN-UP SYSTEM AND VERIFY OPERATION
The process of turning-up the system and verifying operation involves powering up the various
system components, verifying that the LED indicators show normal operation, setting the site
number and name, adjusting the RF signal levels, and adjusting the path delay.

2.1 Turn-Up Procedure
Each Digivance system should be turned-up separately before being networked together with
multiple systems through the CAN interface. Use the following procedure to turn-up each
Digivance system:
1. Temporarily disconnect the external alarm system or notify the alarm system provider that
testing is in progress.
2. If the HU is networked together with multiple HU’s, temporarily disconnect the CAN cables
from 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 IN
port is appropriate for the required RF output signal level and adjust by installing an external
attenuator 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 the
HU or STM front panel. If necessary, a separate laptop computer loaded with the EMS
Version 2.0 software can be temporarily connected and used to initially configure the
system.
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/OFF
switch 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 LED
indicators on the HU, STM and LPA. Refer to Section 5 for the troubleshooting
procedures if the indicators do not respond as specified.
8. Start up the EMS Version 2.0 software program. The EMS main window will open as
shown in Figure 4-1. Note: The EMS software should be installed on a PC-type computer
and the PC’s COM port should be configured to interface with the HU. For information
about installing the EMS software and configuring the PC’s COM port, refer to the
Digivance 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 and
name. This can cause problems for the EMS if multiple HU’s with the same site number
and site name are networked together through the CAN interface. It is therefore necessary
to temporarily disconnect the CAN interface cables from the HU when configuring the
system for operation until a unique site number and name can be assigned.
