q Configuration port — This 2.5 mm mini stereo jack serves the same serial communications
function as the Remote RS-232 port on the transmitter or receiver board, but is easier to
access than the ports on the boards after the units have been installed and cabled. The
9-pin D to 2.5 mm mini jack TRS RS-232 cable
, included with the PowerCage enclosure,
but also available separately, part number 70-335-01 (see figure 12), can be used for this
connection.

NOTES: • This port is for remote control of the transmitter or receiver, not for the
over fiber RS-232 link.
• This port parallels the Remote RS-232 ports on the boards. If an active
front panel configuration connection is made, the board Remote RS-232
port becomes inactive.
• The maximum distances from the transmitter or receiver to the controlling
device can vary up to 200 feet (61 m). Factors such as cable gauge, baud
rates, environment, and output levels (from the unit and the controlling
device) all affect transmission distance. Distances of about 50 feet (15 m)
are typically not a problem. In some cases, the unit may be capable of
serial communications via RS-232 up to 250 feet (76 m) away.
This port is RS-232 only, with the following protocols:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
r Temp LED — This LED lights to indicate that the temperature within the PowerCage
enclosure is at a dangerously high temperature (approximately 167 °F [75 °C]) and that
equipment damage is imminent
.
Operation
After the transmitter, all receivers, and their connected devices are powered up, the system
is fully operational. If any problems are encountered, verify that the cables are routed and
connected properly, and that all display devices have identical resolutions and refresh rates. If
your problems persist, call the Extron S3 Sales & Technical Support Hotline (see the
contact
numbers on the rear of this manual for the Extron office nearest you.)
To take advantage of the various adjustments and test patterns available in the
PowerCage FOX, you need to connect a computer or other RS-232 capable device to the
Remote/RS-232 port on either unit or to the front panel Configuration port and operate
using either
SIS commands or the FOX Extender control program on a computer running
Windows.
