11. New Control program software and FPGA program software will be provided separately
on a “as needed” basis. If new Control and FPGA software is not provided with the
system, proceed to step 12. If a Control and FPGA software upgrade is required, contact
the ADC Technical Assistance Center (see Section 5) for help with the download
procedure.
12. Click on the HOST Config tab and on the REMOTE Config tab (see Figure 3-2). The
HOST Config display and the REMOTE Config display will open within the main window.
13. Enter the Site Name and Site Number for both the HOST and the REMOTE unit. Refer to
Section 2.2 for details.
14. If the Digivance system will be networked together with other Digivance systems,
reconnect the CAN cables to the HU’s NET IN and NET OUT ports.
15. Verify that no Major or Minor alarms are being reported in either the HOST or REMOTE
Alarm displays (except as indicated in the note below) and that all alarm fields are green.
16. Click on the HOST RF tab (see Figure 3-2). The HOST RF display will open within the
main window.
17. Enter the Host Fwd Att (Forward Attenuation) value. This sets the forward input RF
signal level at the HU. Refer to Section 2.3 for details. By default, this value is set to 31
dB. If the DRIVE LED on the HU front panel was red, it should turn green when this step
is completed. Note that 800/900 MHz SMR HU’s have two DRIVE LED’s.
18. Determine if the RF output power at the RU ANTENNA is at the correct level up to a
composite maximum of +38.1 dBm (6.5 Watts) for 800 MHz and 800/900 MHz SMR
systems or +38.3 dBm (6.7 Watts) for 1900 MHz systems. Refer to Section 2.4 for details.
19. Click on the REMOTE RF tab (see Figure 3-2). The REMOTE RF display will open
within the main window.
20. Enter the Remote Fwd Att value. This adjusts the RF output signal level at the HU
ANTENNA port. By default this value is set to 31 dB. Refer to Section 2.5 for details.
21. Click on the HOST RF tab (see Figure 3-2). The HOST RF display will open within the
main window.
22. Enter the Host Rev Att (Reverse Attenuation) values. This sets the reverse output RF
signal levels at the host unit RF OUT port(s). By default each value is set to 31 dB. Refer
to Section 2.6 for details. Note that 800/900 MHz SMR host units have two REVERSE RF
OUT ports.
23. If a delay adjustment is required, enter the Host Fwd Delay and Host Rev Delay values.
By default, the delay values are set to 0. Refer to Section 2.7 for details.
Note: The Site Name and Site Number must be unique for each Digivance system.
Note: The Host RF Underdrive may indicate a minor alarm until the Host Fwd Att and
Remote Fwd Att values are set.
