Remote Control<br />
This section describes the remote control operation of the <strong>FOXBOX</strong> <strong>VGA</strong>,<br />
<strong>FOXBOX</strong> <strong>VGA</strong>/<strong>YUV</strong>, <strong>FOXBOX</strong> <strong>DVI</strong> Plus, <strong>and</strong> <strong>FOXBOX</strong> <strong>DVI</strong>, including:<br />
• Simple Instruction Set Control<br />
• FOX Extenders Control Program<br />
The transmitter <strong>and</strong> receiver each have a Configuration port, a 2.5 mm mini stereo jack<br />
that can be connected to a host device such as a computer running the HyperTerminal<br />
utility, an RS-232 capable PDA, or a control system. These ports make serial control of the<br />
transmitter <strong>and</strong> receiver possible.<br />
The <strong>Extron</strong> 9-pin D to 2.5 mm mini jack TRS RS-232 cable, included with the transmitter,<br />
but available separately, part #70-335-01 (figure 12) can be used for connection to the<br />
Configuration port.<br />

The protocol for the ports is as follows:<br />
• 9600 baud • no parity • 8 data bits<br />
• 1 stop bit • no flow control<br />
NOTES: Only one fiber optic cable, transmitter-<strong>Tx</strong>-to-receiver-<strong>Rx</strong>, is required for<br />
video, audio, <strong>and</strong> serial comm<strong>and</strong> transmission. But, if you connect only one<br />
fiber optic cable, you will not receive RS-232 reports from the controlled<br />
device, <strong>and</strong> there will be reduced RS-232 comm<strong>and</strong> <strong>and</strong> control program<br />
functionality on the <strong>Rx</strong> unit. To receive responses from the controlled device<br />
<strong>and</strong> for full functionality, install both fiber optic cables <strong>and</strong> leave the <strong>FOXBOX</strong><br />
receiver in normal configuration (Mode DIP switch 1 down on the receiver).<br />
