Installation consists of these steps:
• Installing transceivers in the Redundant Transceiver Chassis, if
the chassis was ordered without pre-installed transceivers
• Connecting the internal back-up battery
• Connecting wiring for ground, antenna, data interface, power,
and any alarms
• Programming the transceivers for operation using the
Hand-Held Terminal (HHT)
• Configuring the Redundant Transceiver Chassis for use as a
repeater (optional)
• Optimizing transceiver performance.
5.3 Installing Transceivers
The modular construction of the Redundant Transceiver Chassis
( Figure 7 ) makes it easy to install transceivers. The only tool required is
a Phillips screwdriver.
1. Make sure there is no power applied to the unit.
2. Remove the top cover of the Redundant Transceiver Chassis by
loosening the two screws at the rear panel.
3. If a backup battery is installed in the chassis, be sure it is discon-
nected from the battery control board.
4. Remove the transceiver mounting plate from the chassis (remove the
two screws near the front of the plate).
5. Using 4 6-32 x 5/16 screws for each transceiver, mount the trans-
ceiver(s) to the plate. The mounting screws must extend through the
bottom of the plate into the transceiver case.
Do not use screws longer than 5/16 inch, or damage to the transceiver’s
PC board will occur. If you do not have the right hardware, contact
MDS.
6. Re-install the transceiver mounting plate to the chassis.
7. Connect and secure the interface, power and diagnostics cables to
the transceiver(s).
8. Connect the battery cable to the battery control board.
9. Re-install the top cover of the Redundant Transceiver Chassis.
