FCC ID: F8I-DVLRCSPCS - User Manual - Part 4 ADCP-75-126 • Issue B • April 2002 • Section 4: Operation 2.1 Turn-Up Procedure Use the following procedure to turn-up the system: 1. Temporarily disconnect the external alarm system or notify the alarm system provider that testing is in progress. 2. If turning-up multiple HU and RU systems that have not been configured for operation before, temporarily disconnect the CAN cables from the NET IN and NET OUT ports of each HU.

ADCP-75-126 • Issue B • April 2002 • Section 4: Operation Click to view drop down menu Figure 4-1. Digivance Element Management System Main Window 9. Open the View drop down menu and connect to the Host and Remote pair by selecting “NotNamed/NotNamed”. The HOST Alarms display and the REMOTE Alarms display will open within the main window as shown in Figure 4-2. 10. Download the system software to both the Host and the Remote unit. Refer to Section 2.2 for details.

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.

ADCP-75-126 • Issue B • April 2002 • Section 4: Operation 26. Reconnect the external alarm system or notify the alarm system provider that the turn-up process has been completed. 2.2 Download HU and RU System Software The HU’s and RU’s may require a system software download to make them operational. Use the following procedure to download the system software: 1. Click on the HOST Prg Load tab and on the REMOTE Prg Load tab.

ADCP-75-126 • Issue B • April 2002 • Section 4: Operation Figure 4-4. Select Control Program File 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 Control 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 software download.

ADCP-75-126 • Issue B • April 2002 • Section 4: Operation 4. Calculate the total composite signal power from the BTS using the following formula: Ptot = Pc + 10Log N – (see Note) Where, Ptot is the total composite power in dBm Pc is the power per carrier in dBm as measured in step 2, and N is the total number of channels. Note: Subtract 16.23 dBm if calculating the composite power for a CDMA system. 5.

ADCP-75-126 • Issue B • April 2002 • 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-75-126 • Issue B • April 2002 • 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.

Host Fwd Att Pop-Up Screen 2.6 Determine Output Signal Level at STM Antenna Port The RF output signal level should be measured at the STM ANTENNA port to verify that maximum composite signal level is at the required level. Use the following procedure to determine the power level: 1. Verify that RF ON/OFF switch on the LPA in the OFF position. 2.
PAGE 11
ADCP-75-126 • Issue B • April 2002 • Section 4: Operation 4. Place the RF ON/OFF switch on the LPA in the ON position. 5. Measure the RF level of a single carrier, such as the control channel, in dBm. Make sure the resolution bandwidth of the spectrum analyzer or power meter is narrow enough to measure the power of the single 30 kHz channel only. 6.

ADCP-75-126 • Issue B • April 2002 • Section 4: Operation Right-click here to open the Remote Fwd Att pop-up screen RF output signal level Figure 4-10. REMOTE LPA Display 2. Check the level of the RF output signal (as determined in Section 2.6) against the system design plan specifications. Table 4-1 shows the output signal level required to provide 5 watts per channel for systems with 1 to 4 channels. The maximum output signal level permitted for the system is 43.5 dBm (22.4 watts). 3.

ADCP-75-126 • Issue B • April 2002 • Section 4: Operation Figure 4-11. Remote Fwd Att Pop-Up Screen 6. Verify that the appropriate RF output signal level appears in the RF Pwr-VSWR Low section (see Figure 4-10). This is primarily a reference value and should not take the place of external test equipment when determining the power level of the composite RF output signal.
