FCC ID: F8I-DVLRCS800 - User Manual Part 4
2.1 Turn-Up Procedure
ADCP-75-124 • Issue B • April 2002 • Section 4: Operation
Use the following procedure to turn-up the system:
1. Temporarily disconnect the external alarm system or notify the alarm system provider that
testing is in progress.
2. If turning-up multiple HU and RU systems that have not been configured for operation
before, temporarily disconnect the CAN cables from the NET IN and NET OUT ports of
each HU.
Note: By default, all HU’s and RU’s are programmed with the same site number and
name. This can cause problems for the Digivance EMS if multiple HU’s with the same site
number and site name are networked together through the CAN interface. It is therefore
advisable to temporarily disconnect the CAN interface cables from the HU until a unique
site number and name can be entered for each HU and its corresponding RU.
3. Determine if the forward path composite input signal level at the Host Unit FORWARD
RF IN port is between –10 and –40 dBm and adjust level by installing an external
attenuator if required. 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
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. 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 Digivance EMS 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).

9. Open the View drop down menu and connect to the Host and Remote pair by selecting
“NotNamed/NotNamed”. The HOST Alarms display and the REMOTE Alarms display
will open within the main window as shown in Figure 4-2.
10. Download the system software to both the Host and the Remote unit. Refer to Section 2.2
for details.

11. Click on the HOST Config tab and on the REMOTE Config tab (see Figure 4-2). The
HOST Config display and the REMOTE Config display will open within the main
window.
12. Enter the Site Name and Site Number for both the HOST and the REMOTE unit. Refer to
Section 2.4 for details.
13. Reconnect the CAN cables to the HU’s NET IN and NET OUT ports.
14. Verify that no Major (except Major Extern Alarm) or Minor alarms are being reported in
either the HOST or REMOTE Alarm displays and that all alarm fields (except Major
Extern Alarm) are green.
15. Click on the HOST RF tab (see Figure 4-2). The HOST RF display will open within the
main window.
16. Enter the Host Fwd Att (Forward Attenuation) values. This sets the forward input RF signal
level at the HU. Refer to Section 2.5 for details. By default, this value is set to 0 dB. If the
DRIVE LED on the HU front panel was red, it should turn green when this step is completed.
17. Determine if the RF output power at the STM ANTENNA is at the correct level per
channel up to a composite maximum of +44.5 dBm. Refer to Section 2.6 for details.
18. Click on the REMOTE LPA tab (see Figure 4-2). The REMOTE PA display will open
within the main window.
19. Enter the Remote Fwd Att value. This adjusts the RF output signal level at the STM
ANTENNA port. Refer to Section 2.7 for details. By default this value is set to 0 dB.
20. Place the RF ON/OFF switch (on LPA front panel) in the ON position.
21. Verify that the SHUTDOWN LED indicator (on LPA front panel) turns from red to off and
the Digital Display message changes from FORCED SHUTDOWN to NORMAL
OPERATION.
22. Click on the HOST RF tab (see Figure 4-2). The HOST RF display will open within the
main window.
23. Enter the Host Rev Att (Reverse Attenuation), and Host Div Rev Att (Diversity Reverse
Attenuation) values. This sets the reverse output RF signal levels at the HU. Refer to
Section 2.8 for details.
24. If a delay adjustment is required per the system design plan, enter the Host Fwd Delay,
Host Rev Delay, and Host Div Rev Delay values. By default, the delay values are set to 0.
Refer to Section 2.9 for details.
25. If a separate laptop computer loaded with the EMS software was used to initially
configure the system, disconnect the laptop computer from the SERVICE connector on the
HU front panel.
Note: Each HU and RU pair will generally remain permanently connected to a PC-type
desktop computer loaded with the EMS software. When two or more systems are
connected together through the CAN interface, only one EMS computer is required to
manage the networked HU and RU systems. The EMS computer may be connected to the
SERVICE port on any one of the HUs in the network.
