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 43.5 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.
