stereo-style (tip-ring-sleeve) jack. The Extron 9-pin D to 2.5 mm stereo mini TRS
RS-232 cable (shown below), provided with the PowerCage 1600 Enclosure, can be
used for this connection.

9-pin TRS RS-232 Cable
RS-232 protocol varies depending on the board with which the computer is
communicating (see “
”
in the “Reference Information” section), but all
boards accept this basic protocol:
z
9600 baud
•
no parity
•
8 data bits
z
1 stop bit
•
no flow control
NOTE: The maximum distances from the transceiver 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).

Temp LED — This LED lights when the enclosure is operating at a dangerously high
temperature (approximately 167 °F [75°C]) and equipment damage is imminent. If the
Temp LED lights, power down the unit, ensure adequate ventilation, and allow the
PowerCage system to cool before restoring power.
CAUTION: If this LED lights, remove power from the unit and contact Extron S3
Sales & Technical Support Hotline.
Daisy-chain Connection
When configured as a dedicated receiver, the PowerCage FOX 3G HD-SDI can pass a
signal along a daisy chain of to up to 10 receivers, with a display device attached to each.
All receivers in the chain must be compatible; in other words, they must all be SM or all
be MM models, connected with the appropriate fiber optic cable. Each FOX 3G receives a
signal at its Rx fiber optic port and passes the signal to the next unit through its Tx port.
