Turning Voltage from TCU to TXU On or Off
This screen lets you turn the voltage on or off from the TCU to the TXU.
On systems where both the TCU and TXU are used together, the units can be
powered in one two ways:
• Separately, that is, individual power connections from a power supply to
each unit.
• Or, the TXU can be powered from the TCU. In this configuration DC voltage
is superimposed on the IF cable which connects from the TCU to the TXU.

Model Variations
Certain STRATA Transmitters are shipped with “DC Override” switches which
provide added control to turn DC superimposed voltage on or off.
Warning: It’s important to identify which model
transmitter you are using. Failure to do so make
cause damage to the unit. For more information,
see "
Powering the STRATA Transmitter,"

place the transmitter in transmit mode by pressing the control switch for
one second. The front panel “XMIT” LED (blue) should light.
