SIS commands for the PowerCage FOX Tx/Rx AV are shown in the “
” section.
NOTE: Both RS-232 Remote and RS-232 Over Fiber signals require fiber optic
Link 1 and Link 2 for full functionality.
If only Link 1 is enabled, the ability to configure the system through
SIS commands is limited by the lack of return communication from the
receiver to the transmitter.
•
All configuration carried out using the transmitter is processed normally
because only fiber Link 1 is required for it.
•
Queries from the transmitter about the status of receiver settings are
not processed correctly because fiber Link 2 is required to carry the
return signal.
•
The receiver cannot be used to configure the transmitter because fiber
Link 2 is required.
Lack of communication between the transmitter and the receiver can result in
mismatches in the value settings of the two units, which may cause confusion with
control systems or software applications. To avoid this, within 4 seconds of Link 2
becoming active, the receiver settings are automatically copied to the transmitter to
ensure that settings for both units match.
NOTE: When the receiver settings are copied to the transmitter, existing
transmitter settings are overwritten and it may be necessary to update
those values.

Captive Screw Connection for Rear Panel RS-232 Over Fiber 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 PowerCage FOX Tx/Rx AV does not respond 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.
