SIS Command Validity Table
If only one fiber optic channel 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 commands issued through the transmitter are valid because link 1 allows signals to be
forwarded to the receiver. However, responses to queries originating from the transmitter
about the status of the receiver return invalid data.
All configuration of the receiver by commands issued through the receiver is valid. Attempts
to configure the the transmitter through the receiver in the absence of link 2 are invalid.
The following table shows the validity of commands issued through the receiver when only
link 1 is active:
Adjustment
Color Valid
Tint Valid
Brightness Valid
Contrast Valid
Audio gain/attenuation Invalid
Audio mute Valid
Audio output level Valid
Output configuration Valid
Input configuration Invalid
Daisy chain mode Valid
Test pattern Valid
Video mute Valid

The Extron FOX Extender Control Program communicates with the transmitter and receiver
pair via the rear panel Remote RS-232 port or front panel configuration port of either unit.
The program is compatible with Windows® 2000, Windows XP and later versions of
Windows. Upgrades to the control program can be downloaded from the Extron Website
(www.extron.com).
