4. Commissioning 4.1. Connection step by step Figure 11 Figure 11; RF ports and Power Cable Glands location. 1. Connect service antennas to the To Mobile Port. N type female connectors are used in the Signal Booster. 2. Connect the donor antenna to the To Base RF Port. N type female connectors are used in the Signal Booster. 3. Once the RF ports of the Signal Booster are properly loaded connect the Main AC power.
Figure 12 If the Signal Booster has the NFPA Option, there is a dedicated cable gland for this purpose (“NFPA” in figure 11). A multi-conductor cable can be used to connect the NFPA dry contacts to the Fire Department Control Box. 4.
5. Once the Signal Booster is connected to the power source, it takes about 40 seconds to run a booting routine. After that time, the Signal Booster is ready to be connected via USB cable to a computer running Fiplex Control Software (FCS) to be properly configured.
5. Starting Operation BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM. UM-0821 1. Turn on the Digital Signal Booster, connect computer to Signal Booster through USB cable, and run Fiplex Control Software. It is recommend to turn off the power amplifiers. 2. Setup desired channel frequencies. Since Fiplex Signal Booster is channel selective, user has to know what frequencies are used in base station. 3.
4. Setup desired operating gain using FCS. UL and DL chain are independent, so both values must be set. To set DL band gain is recommended that AGC works around 3 - 6dB in each channel, in this way, maximum output power is achieved. 5. Set up squelch settings. Controls are independent in UL and DL bands. Typical values for UL are 110dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level received in any active channel minus 10dB. 6.
Status Indicators There is an indicator panel located at bottom of the Signal Boosters door. This led panel works as a status monitor, in order indicate warning or alarms of Signal Booster. The LED panel has four LEDs, the first one the power ON indication led, labelled “PWR”. The Second LED, labelled “STS” summarizes warnings regarding critical operational conditions of the Signal Booster.
The third and fourth LED summarizes operational conditions for uplink “UL” and downlink “DL” chains. In general, the LEDs have four states: “off”, “slow blinking”, “fast blinking” and “on”. Table 1 describes alarm and warning conditions for each led state.
Laboratory Measurements For specific parameters verification and laboratory tests, please contact factory. Detailed procedures, recommended tests set up, and a knowledge engineering team will bring adequate support to perform this measurements in a comfortable and safely way.
