10. 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, skip this step and proceed to step 11. If new Control and FPGA software is

provided, check the version numbers of the new software against the version numbers of

the software loaded on the Host and Remote Units. If the software loaded on the Host and

Remote Units is older than the new software, download the new software to both the Host

Unit 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 3-2). 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. 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.

14. Verify that no Major or Minor alarms (except Major or Minor Extern Alarm) are being

reported in either the HOST or REMOTE Alarm displays (except as indicated in the note

below) and that all alarm fields (except Major or Minor Extern Alarm) are green.

15. Click on the HOST RF tab (see Figure 3-2). The HOST RF display will open within the

main window.

16. Enter the Host Fwd Att (Forward Attenuation) value. 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 31

dB. If the DRIVE 851–869 and DRIVE 935–940 LED’s on the HU front panel were red,

both 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 +43.4 dBm (22 Watts). Refer to Section 2.6 for

details.

18. Place the RF ON/OFF switch on the LPA in the ON position.

19. Verify that the SHUTDOWN LED indicator on the LPA turns from red to off and the

Digital Display message changes from FORCED SHUTDOWN to NORMAL

OPERATION.

20. Click on the REMOTE RF tab (see Figure 3-2). The REMOTE RF display will open

within the main window.

21. Enter the Remote Fwd Att value. This adjusts the RF output signal level at the STM

ANTENNA port. By default this value is set to 31 dB. Refer to Section 2.7 for details.

22. Click on the HOST RF tab (see Figure 3-2). The HOST RF display will open within the

main window.

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. The Remote LPA disable will indicate a major alarm until

the LPA is enabled.
