Rear Panel RS-232 Remote Port
In addition, on the rear panel, the units have RS-232 Over Fiber pass-through ports. These
ports allow RS-232 commands to be passed from the control device to remote devices over
the fiber optic cable with speeds up to 115 kbps.
NOTE: The FOX Tx/Rx AV does not respond to, or generate a response to, any
commands passed through the “RS-232 Over Fiber” ports. Refer to the user
guide of the device being controlled for the appropriate SIS commands.
