Introduction
1.2
System Power
STRATA Transmitter Units can be powered from any DC source. The voltage
required depends on the number of units in the system, and whether the units
are physically separated. In addition, in applications where units are physically
separated, the DC voltage can be superimposed on the IF and RF signals
allowing the system to be powered from a single unit.
For more information, see "
Powering the STRATA Transmitter," Section 3 on
page 3-1
.

System Communications Links
A STRATA Transmitter system provides a communication link between units.
Information is passed between the TCU and TXU on the IF signal, and between
the TXU and HPU on the RF signal. This feature allows an operator to control
every component of the system from either the TCU or TXU.

Orderwire Communication
Orderwire communications at speeds up to xx provide an addition data carrier for
communications between links. Connection to the transmitter is made to the
serial connector. See Appendix C for connections and cabling.

STRATA Tx Configurator Software
STRATA TX Configuration Software is shipped with every STRAT transmitter.
System presets are set at the factory depending on the customer order.
Changes can be made to existing presets using the TX Configuration menu
system (
Figure 1-4
).
A PC or laptop computer connects to the serial port of the TCU or TXU. Once
connected, the following functions are possible:
• Upload current presets from the system to the PC.
• Make modifications to current presets and download back to the system.
• Store multiple presets to the PC using unique file names.
Storing presets allows the user the flexibility of storing multiple sets of system
presets to be recalled later.
