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.
N The FOX 2G Tx/Rx AV will not respond to, or generate
a response to, any commands passed through the
"RS-232 Over Fiber" ports. Refer to the user's manual
of the device being controlled for the appropriate SIS
commands.
