TCU SIGNAL OUT Connector The TNC type SIGNAL OUT
connector provides ASI, CODFM - IF, IF, or IF composite video
output signals, depending upon the options contained in the unit.
In addition, if the TCU is used in conjunction with a separately
located TXU, DC power to or from the TXU is superimposed on
the output signal coaxial cable between the TXU and TCU.
TCU Monitor (MON) Connector If your TCU has COFDM/
MPEG installed, this rear panel output connector can be
configured (when operating in the digital mode) to provide either:
•70 MHz IF
• ASI (output of COFDM modulator, before decoding)
If your TCU is equipped with an analog modulator, this connector
provides only the 70 MHz IF signal output.
TCU SIGNAL IN Connector Video connections are made to
the BNC SIGNAL IN connector. Video input selections are
made by selecting Presets from the front panel Control Switch.
Presets are created using the STRATA TX Configurator
software. For more information, see the “Advanced Operation”
Chapter on page 5-1 (part of the STRATA TX System Technical
Reference Manual only).
