Serial Ports
The receiver board has an RS-232 serial port on three pins of a 5-pole captive screw
connector that can be connected to a host device (see item
g
on page 6).
The PowerCage enclosure has a Configuration port, a 2.5 mm mini stereo jack, that
parallels the board ports (see item
e
on page 12).
These serial ports make serial control of the transmitter and receiver possible, using devices
such as a computer running the Extron DataViewer or MicroSoft HyperTerminal utility or a
control system.
The protocol for all ports is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
NOTE: The Remote RS-232 port is active only if the PowerCage Configuration port is
not active. If an active Configuration port connection is made, the Remote RS-
232 port for that board becomes inactive.
Simple Instruction Set Control
Host-to-Unit Instructions
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
unit executes the command and sends a response to the host device. All responses from
the unit to the host end with a carriage return and a line feed (CR/LF =
]
), which signals the
end of the response character string. A string is one or more characters.
