RS-232 Ports

The transmitter and receiver boards each have an RS-232 serial port on a 3-pin captive
screw connector that can be connected to a host device such as a computer running
the HyperTerminal utility, an RS-232 capable PDA, or a control system. The PowerCage
enclosure has a Configuration port, a 2.5 mm mini stereo jack, that parallels the board
ports. These ports make serial control of the transmitter and receiver possible.
The protocol for both ports is:

z

9600 baud

no parity

8 data bits

z

1 stop bit

no flow control

NOTES:

For each PowerCage FOX Tx/Rx AV board, the Remote RS-232 port is active

only if the Config port on the PowerCage enclosure is not active. If an
active configuration port connection is made, the Remote RS-232 port on
the board becomes inactive.

Only one fiber optic cable, transmitter-to-receiver, is required for video,

audio, and serial command transmission. However, if you connect only one
fiber optic cable, you do not receive RS-232 reports from the controlled
device, and there is reduced RS-232 command and control program
functionality on the Rx unit. To receive responses from the controlled device
and for full functionality, install both fiber optic cables and set the receiver
to its normal configuration (via the
