1. Leaving unconnected pins G and H of the Relay interface (see
2. Sending a mute command in terminal mode through the serial interface.
This feature is useful if the user wishes to perform a maintenance check or to check out the
transmission system.
4.3.8.3 Rx MUTE Control
The user can remove the RF output power for the Rx path remotely by:
1. Leaving unconnected pins J and H of the Relay interface (see
2. Sending a mute command in terminal mode through the serial interface.

Power Supply Module
pr12 VDC, +5 VDC and –9 VDC outputs to all of the
internal modules.
The se48 VDC is necessary to operate the cooling fan. The voltage is variable and
temperature dependent that will ensure a variable rotation speed of the cooling fan related to the
temperature (the fan will rotate slower when the temperature is low and faster when the
temperature is high).
The power supply is configured to operate from a 90-138 or 180-264V AC (autoranging),
47-63 Hz, single phase supply, or from 48 V DC (see specifications).
