39
8 RS232 PORT
8.1 Connection
Your unit is fitted with a standard ‘D9’ socket allowing it to be controlled from a
computer or other type of terminal or console with a similar interface.
A ‘null-modem’ is not required. See the Specifications section for a detailed pin
connection list.
The default baud rate is 57600 with 8 data bits, 1 stop bit and no parity. This baud
rate can be changed in the System menu to suit other programs if need be.
8.2 Communications protocol
The standard communications protocol for your unit is text-based and is detailed on
section 9.1
The protocol is also bi-directional (unit and computer both send messages to each
other), so that you can send changes to the unit, and it will also respond with any
changes made via alternate methods (front panel buttons, menu changes and infra-
red control). This enables any attached computer to be aware of any changes
made to the unit from an alternative source rather than itself.
Note: Any command you send to the unit will be replied to either with an error code
or with the actual changed value. This may be different to the one you sent; for
example, if trying to set a value too high or too low.
