MT-3 Radio Systems
6.
Interc9.5 Vdc and +13.8 Vdc power between subrack units if one of the subracks does not
include a system monitor (no system monitor is required for a second subrack with only power ampli-
fiers mounted in it).
7
. Install the modules in to the guide rail slots if not already configured. Adjust the guide rails for the
correct module positions if required (see the SR-3 subrack instruction manual). When installing mod-
ules, ensure the quick release fasteners on the top and the bottom of the modules are in the unlocked (slot
should be horizontal) position before insertion to the guide rails. To lock the quick release fasteners, push
and turn the fastener 90 degrees with a flat screwdriver.
Note: MT-3 modules may be removed or inserted from the subrack while power is supplied without dam-
aging the equipment.
8.
Subrack and module operation is dependent on a series of shunts and jumpers throughout the RF mod-
ules, control modules and subrack. Review the Application Specific manual, and the receiver, transmit-
ter and subrack manuals to confirm system operation.
9.
If control of the radio system is handled by a third party controller, a terminal strip connector should
be connected to the P1 auxiliary connector on the rear of the subrack. All wiring should be made to this
screw-type terminal connector.
10.
For some applications, a cable, not a terminal strip connector, is used to connect to the auxiliary con-
nector. The cable must be plugged into the P1 auxiliary connector on the rear of the subrack. Ensure
locking tabs on the connector are completely engaged.
Receiver and Transmitter Modules
1
. Check the frequency label to confirm that the receiver or transmitter is set up to operate on the desired
channel.
2.
Connect the RF cables and ensure they are firmly screwed on.
3.
Operate the transmitter with a 50
Ω
load and confirm the power output is at the desired level. Adjust
the internal RF power control (inside the transmitter) for the correct power level if required. This may
be required for your nominal supply voltage if it is not 13.8 Vdc.
