FCC ID: F8I-DLCSMR2A User Manual - Part 5
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.
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 w i ndow.
16. Enter the Host Fwd Att (Forward Attenuation) values. This sets the forward input RF signal level at the HU . Ref er 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.
ADCP-75-159 Issue 1 August 2003 Section 4: Operation
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 pa nel ) in the NORM position.
19. Verify that the STATUS indicator (on LPA front panel) tur ns 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 S ection 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 w i ndow.
23. Enter the Host Rev Att (Reverse Attenuation). This sets the reverse output RF signal leve ls 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 Dela y 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 lapt op computer from the S ERVICE connector on the HU front panel.
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.
26. Reco nnect the externa l alarm system or notify the alarm system provider tha t the turn-up process has been completed.

2.2 Verify/Download HU and RU System Software
The HU’s and RU’s may require a system software download if they are not loaded with the current system software. 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 R EMOTE Prg Load tab. The HOST Prg Load display and the Remote Prg Load display will open within the EMS main window as shown in Figure 4-3.
Click to start down­load to HOST.
Click to open Select Control Program window for HOST
Verify software version before starting download.
Click to start down­load to REMOTE.
Click to open Select Control Program win­dow for REMOTE.
Verify software version before starting download.

2. Click on the HOST Select button (see Figure 4-3). The Select Control Program File window will open as shown in Figure 4-4. Browse until the folder where the Control Program files are locate d is selected and the software files are displayed in the window.
3. Check the software version numbers shown in the Software Info section of the Prg Load display against the version numbers of the software files displayed in the Select Cont rol Program File window. If files in the Select Control Program File window are a later version than those shown in the Prg Load display , proceed with the softw are download. If the version numbers shown in the Software Info section are the same as the version numbers of the files in the Select Control Program File window, the software download is not required.

4. Select the first file to download and click on the OK button.
5. Click on the HOST Load b utton (see Figure 4-3) to st art th e dow nloa d .
6. Repeat steps 4 and 5 for each fil e that requires downloading.
7. Repeat steps 2 through 5 for the REMOTE.
2.3 Determine Forward Path Input Signal Level
The level of the composite RF input signal at the FORWARD RF IN port at the HU will vary depending on the type of EBTS, the cable loss, the number of c hannels present, a nd the required forward path c omposite power. If maximum composite RF output is required, the signal level of the composite forward path RF signal at the HU forward path input must be adjusted to fall within a range of –20 to –40 dBm. If the signal level is not within thi s r ange, it must be adjusted to fall within this range through the use of an external attenuator capable of handling the EBTS forward path output power.
If using the SMR Primary Interface Panel or Expansion Panel, refer to the Digivance LRCS Interface Panels User Manual (ADCP-75-143) for the procedures for measuring and adjusting the input RF signal level at the HU. If connecting a single HU to a single EBTS, use the following pr ocedure to measure and adjust the input RF signal level at the HU:
1. Connect a spectrum analyzer or power meter to the forward path output port of the EBTS. The required signal levels and test points are shown in Figure 4-5.
Note: Check the input rating of the test equipment and the output rating of the EBTS. To avoid burning out the spectrum analyzer or power meter, it may be necessary to insert a 30 dB 100W (or similar) attenuator bet ween the EBTS and test equipment.
2. If using a spectrum analyzer, proceed to step 3. If using a power meter, measure the composite signal po wer from the EBTS and then proceed to step 5.
3. Measu re the RF level of a single ca rrier, such as the con trol channe l, in dBm. Mak e sure the resolution bandwidth of the spectrum analyzer is 30 kHz. Maximum power in any channel should not exce ed 5W (+37 dB).
