FOXBOX 4G Tx/Rx • Remote Control
3-2
3-3
The transmitter and receiver each have a front panel
Configuration (RS-232) port, a 2.5 mm mini stereo jack, that
can be connected to a host device such as a computer running
the HyperTerminal or other utility, an RS-232 capable PDA,
or a control system. These ports make serial control of the
transmitter and receiver possible.
The protocol for the ports on both units is as follows:
• RS-232
• 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• no flow control
N
Only one fiber optic cable, transmitter Tx to receiver
Rx, is required for video, audio, and serial command
transmission. But, if you connect only one fiber optic
cable, or you configure the receiver for daisy-chaining,
you will
not
receive RS-232 reports from the controlled
device, and there will be
reduced
RS-232 command
functionality on the Rx unit. To receive responses from
the controlled device and for full functionality, you need
to install both fiber optic cables and leave the FOXBOX
receiver in normal configuration (the receiver's Mode
DIP switch 1 down).
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 that begins on page 3-6. The symbols
represent variables in the unit-initiated messages and the
command/response table fields.
