SIS Commands
The FOX T/R USB Extender Plus can be remotely set up and controlled via a host computer
(the same computer to which the Host port of the transmitter is connected, or a different
one) or other device (such as a control system) that is attached to the front panel Config
port of either the transmitter or receiver. See
Connecting for Serial Communication
on
page 13 for information on connecting to this port.
You can issue SIS commands to the extender using your computer RS-232 interface with a
communication software program such as Extron DataViewer or HyperTerminal.
NOTE:
All SIS commands except those enabling peripheral emulation must be issued
to
both
the transmitter and receiver. For example, after connecting the host computer
to the transmitter and issuing commands, you must disconnect the RS-232 cable from
the transmitter, connect the cable to the receiver, then reissue the same commands to
the receiver.
Host-to-Extender Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the FOX T/R USB Extender Plus
determines that a command that was entered is valid, it executes the command and sends
a response to the host device. Most responses from the extender to the host computer
end with a carriage return and a line feed (
CR/LF
= ]), which signals the end of the response
character string. A string is one or more characters.
