3.3 R280 INSTALLATION
NOTE: The unit attenuator has been factory set to the maximum value (30 dB)
at time of shipment. This results in a typical unit gain of 40 dB. The
installer must know the base station signal level to be fed into the unit.
The gain of the unit must be set to a value such that the Rated Output
Power of +19 dBm is not exceeded. The unit must not be operated
above this Rated Output Power as specified in Tables 1-1 and in 1-2.
The Repeater is designed for mounting on a flat vertical surface. Proceed as follows:
1. Locate a suitable mounting location allowing a clearance to route mating cable and
connectors to the unit. Drill four pilot holes on 10.5 x 17.9 inch centers for 3/8" bolts.
Refer to the installation diagram shown in Figure 3-1.
2. Mount the unit ensuring there is good air circulation.
3. Set the unit attenuator according to the above note such that the Rated Output Power is
never exceeded.
4. Connect "BASE" to the cable leading to the base antenna.
5. Connect "DISTRIBUTION" to the cable leading to the distribution antenna.
6. If desired, connect external alarm monitoring equipment to the interface module relay
contact terminals as required.
7. Connect external DC power to the DIN receptacle on the bottom of the unit. The unit
may be powered by DC voltages in the range of 11-15 VDC (negative ground). The unit
is typically powered with the PS338 AC to 12 VDC adapter provided with the unit.
This completes the installation.
3.4 OPERATING INSTRUCTIONS
When powered, the unit green LED on the Interface module will be illuminated and the
alarm relay terminals will be in their normal condition.
When the unit is first turned on, the red LED may illuminate briefly and the alarm relay
may switch to indicate an alarm condition while the PLLs are locking and the modules
are disabled. Under normal operation, only the green LED will be on.
