Routine Operation 3-12STRATA TX Operator’s Guide/Tech Ref Manual
If you’re using a STRATA ACU, connect the AC input
to AC power and connect the DC output to the TXU
and TCU.
If you are unsure of the power requirements or the
connections, refer to the “Installation” Chapter on
page 6-1 (part of the STRATA TX System Technical
Reference Manual only).
5. Connect the TXU (or TCU) inputs to your audio and
video equipment.

3.3.3 Powering the STRATA TX System
The STRATA TX System will be in one of two configurations
which provide different options for controlling application of DC
power between units. Model variations are as follows:
Superimposing DC Power In this configuration, DC power is
superimposed with the IF signals between units and there is no
manual control of DC power from the TCU. The DC power is
superimposed on the coaxial cable between the TCU and the
TXU.
To turn DC power on and off, the operator uses the TCU and
TXU front panel PWR switches and either the TCU or TXU
Control Switch and alphanumeric display menus. The TXU DC
ON COAX switch must be set to ON.
Superimposing DC Power with Manual Control In this
configuration, DC power superimposed on the IF signals
between the units is manually controlled. The operator can
manually turn DC power on or off to the TXU from the TCU or to
the TCU from the TXU and from the TXU to the HPU using DC
ON COAX switches and TCU or TXU front panel Control
Switches and alphanumeric display menus.
The DC ON COAX switches provide the manual control and
must be set to ON to allow application of DC power to the TXU ,
and TCU using the Control Switches and alphanumeric display
menus.
Powering STRATA TX Systems The method you use to power
up your STRATA TX System will vary, depending upon the
following:
• The model of your STRATA TX System, whether or not
you have DC power manual override control.
• The transmitter configuration, whether you are using a
single TCU, a single TXU, or a TCU and TXU
