3.6.2 Installation
Components Required:
1. Coaxial Relay Assy complete with Rx cable connected. Qty-1
2. RG58 cable Assy complete with ‘N’ Type connector fitted. Qty-1
3. 13mm hole grommet. Qty-1
4. 3x8mm pozi-drive screw. Qty-2
5. Rear Connector Label Qty-1
Test Equipment Required:
1. Communications Test Set
2. MX800 Radio Interface Box
Method:
1. Remove the cover to the MX800 radio.
2. Remove the existing Receiver coaxial feeder cable assy.
3. Install the 13mm grommet into the 13mm hole where the BNC Rx
connector is normally located.
4. Place the RG58 cable Assy through the grommet so that the ‘N’ Type
connector will mate with the ‘N’ Type female connector on the PA
module.
5. Remove the 4x Phillips screws and connector cover from the TX side of
the coax relay assy.
6. Solder the centre of the RG58 Cable Assy to the centre pin on the TX
side of the coaxial relay. The outer sheath of the coax cable should be
placed such that it sits equal with the outer edge of the relay body.
7. Place the connector cover over the TX cable on the relay and screw the
cover in place. Take extreme care to not over-tighten the screws and
prevent stripping of the threads in the relay body.
8. Install the relay Assy into the MX800 with the relay coil on the opposite
side of the relay to the DC power connector. Secure with the 2 of
3x8mm screws provided.
9. Route the Rx coaxial cable to the Rx unit input RF connector.
