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 each 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.
