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. If the site has multiple host units, 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 +40.5 dBm. Refer to Section 2.6 for details.

18. Place the MUTE/NORM/RESET switch (on LPA front panel) in the NORM position.

19. Verify that the STATUS indicator (on LPA front panel) turns from steady green to blinking

green.

20. Click on the REMOTE LPA tab (see Figure 4-2). The REMOTE PA 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. Refer to Section 2.7 for details. By default this value is set to 0 dB.

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). 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

and Host 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.

26. Reconnect the external alarm system or notify the alarm system provider that the turn-up

process has been completed.

Note: For continuous monitoring of alarms, each HU and RU pair must 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.

Use the following procedure to check the version number of the system software and if necessary to download the current system software: 1. Click on the HOST Prg Load tab and on the REMOTE Prg Load tab.

ADCP-75-159 • Issue 1 • August 2003 • Section 4: Operation 4. Calculate the total composite signal power from the EBTS using the following formula: Ptot = Pc + 10Log N Where, Ptot is the total composite power in dBm Pc is the power per carrier in dBm as measured in step 3, and N is the total number of channels. 5. Determine the total cable loss that is imposed by the forward path coaxial cable that links the EBTS to the HU and also any insertion loss imposed by splitters or combiners. 6.

ADCP-75-159 • Issue 1 • August 2003 • Section 4: Operation 2.4 Enter Site Name and Site Number All HU’s and RU’s are programmed with the same site name and site number. It is therefore necessary to assign a unique site name and site number to the HU and RU before they can be connected to the same CAN. Use the following procedure to assign a unique site name and number to each HU and RU system: 1. Click on the HOST Config tab and on the REMOTE Config tab.

ADCP-75-159 • Issue 1 • August 2003 • Section 4: Operation 3. Right-click on the HOST Site Number (see Figure 4-6). The Site Number pop-up screen will open. Enter any number between 1 and 24 and then click on OK to close the screen and make the changes take effect. 4. Check the REMOTE Site Number field (see Figure 4-6). The REMOTE Site Number does not have to be entered. When the HOST Site Number is entered, the system will automatically enter the same number for the REMOTE Site Number. 5.
