7.6 DIP Switches
There are eight DIP switches on the rear panel of the Matrix (see drawing below). For all DIP
switches, the up position indicates the on condition, and the down position the off condition. The
function of these switches is shown below.
DIP switches 5 and 6 allow the RS-232 baud rate to be fixed at one of three values: 9600, 19200 or
38400. The AVM supports 38400 at the embedded level and that speed can be used for Crestron and
AMX programming, but since Windows® does not support that rate, the AVM GUI cannot be run at
38400.
DIP switch 7 allows the RS-232 checksum and escape byte to be toggled on or off. These should be
turned
off
in installations which include a permanent RS-232 controller, such as AMX, Crestron or custom
PC program. This greatly simplifies coding (and decoding) the RS-232 messages. The RS-232 checksum
and escape byte should be turned
on
in installations where the RS-232 communication may be hindered
because of cable length (greater than 50 feet) or shielding from external electronic noise.
