SERIAL INTERFACE
The NuPower Xtender includes an RS-485 serial interface for adjusting linearization parameters via a
serial terminal program, such as
Termite
.
The serial port must be configured with the following attributes:
•
Baud rate: 9600 bps
•
Data bits: 8
•
Stop bits: 1
•
Parity: None
This section provides the user with the command syntax necessary to properly configure the
bidirectional amplifier module for use. All commands have the following attributes:
•
A command consists of a string of characters, followed by a terminating Carriage Return
character,
¿
(hex 0D).

and the CONSTO command is not entered, the Xtender will return to the last stored setting upon unit
power cycling, and the changes will be lost.
The “CONDEF” co
mmand is used to return the Xtender to the factory default settings.
