About the FOX T USW 203
The Extron FOX T USW 203 is a three input universal switcher with a fiber optic transmitter
that provides long haul transmission of HDCP-compliant HDMI, RGBHV, or HD component
video, stereo audio, and RS-232 signals over fiber optic cabling. The transmitter delivers
pixel-for-pixel transmission of images up to 1920x1200, including HDTV 1080p/60.
The switcher and a compatible FOX Series receiver can be controlled and configured using
Simple Instruction Set (SIS) commands (see Simple Instruction Set Control on page 12) or
the FOX Extenders Control Program (see FOX Extenders Control Program on page 20).

The FOX T USW 203 operates in either of two modes, selected under RS-232 control, for
compatibility with other, non-HDMI, units:
• Plus — Supports resolutions up to 1920x1200 and 1080p @ 60Hz. The fiber optic
output of the switcher can be received only by one of six receivers: a FOXBOX HDMI Rx,
FOXBOX DVI Plus Rx, PowerCage HDMI Rx, PowerCage FOX DVI Plus Rx,
FOXBOX SR HDMI, and PowerCage FOX SR HDMI.
• Non-Plus — Supports resolutions up to 1600x1200 @ 60 Hz. The fiber optic output of
the transmitter can be received by any FOXBOX, PowerCage FOX, and FOX 500 VGA
and DVI unit, including the Plus and non-Plus units.
