TXU and TCU
Power Down
1. Set the TXU PWR switch to 0 (off).
2. Set the TCU PWR switch to 0 (off).
3. If the TXU and TCU are powered from the optional
ACU, set the ACU power switch to 0 (off).
If the TCU and TXU are powered from a source other
than an ACU, turn that power source off.
3.3.7 TXU and TCU Power Up and Power Down -
Separate Locations
If your STRATA TX System consists of a TXU and a TCU and the
TCU is located in a separate location from the TXU, the TXU will
be powered using the superimposed DC power on the coaxial
cable between the TCU and the TXU or the TCU will be powered
using DC power superimposed on the coaxial cable from the
TXU.

Perform the following steps to power up or power down a
separately located TXU and TCU TX System:
CAUTION
To avoid possible damage, turn off DC
Power on the coax before connecting any
test equipment.
Power Up
1. Verify the power cable is properly connected to the
TCU rear panel POWER connector.
Note If your TCU does not have a DC ON COAX
switch, go to step 3.
2. Turn the recessed DC ON COAX switch on the front
panel of the TCU until the screw slot of the switch
points to ON.
3. Turn the recessed DC ON COAX switch on the front
panel of the TXU until the screw slot of the switch
points to ON.
4. Verify all coaxial cables and connectors have been
properly connected.
Note
When the TCU and TXU are mounted in separate
locations, it is recommended that DC input power
be connected to the TXU.
Since either unit may be powered from the other
unit via DC power superimposed on the coaxial
cable between the units, DC input power may
therefore be applied to either the TXU or the TCU.
