The transmitter and receiver each has two serial ports 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. These ports make serial control of the transmitter and
receiver possible. The serial ports are:
• The rear panel Remote RS-232 port on 3-pin captive screw
connectors
• The front panel Configuration (RS-232) port, a 2.5 mm
mini stereo jack
The protocol for all ports is as follows:
• 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• no flow control
N
For each unit, the rear panel Remote RS-232 port is active
only if the front panel Configuration port is not in use. If
a front panel configuration connection is made, the rear
panel Remote RS-232 port becomes inactive and the front
panel Configuration port is active.
N
Only one fiber optic cable, Optical 1, is required for video,
audio, and serial command transmission. But, if you
connect only one fiber optic cable, you will not receive
RS-232 reports from the controlled device, and there will be
reduced RS-232 command and Windows control program
functionality on the RX unit. To receive responses from
the controlled device and for full functionality, you will
need to install both fiber optic cables.

Front Panel Configuration Port
N
The front panel configuration ports parallel the rear panel
Remote RS-232 ports. If a front panel configuration
connection is made on either unit, that unit's rear panel
Remote RS-232 port becomes inactive and the front panel
Configuration port is active.
The optional 9-pin D to 2.5 mm mini jack TRS RS-232 cable,
part
#70-335-01
(figure 4-2) can be used for connection to the
Configuration port.

Simple Instruction Set Control
Host-to-interface communications
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.
Symbol definitions
Symbols (variables), defined on the next page, are used
throughout the "Unit-initiated messages" section and the
command/response table on page 4-8. The symbols represent
variables in the unit-initiated messages and the command/
response table fields.
