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
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
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 (
character string. A string is one or more characters.
