Question:  

I get "Baud Timeout" when doing Axcent3 diagnostics in the terminal emulator.  What can be done to stop this?

Answer:

The Axcent 3 defaults to an "AutoBaud" mode which sets the master port communications to the data rate that is used by the attached PC.  If the PC stops communicating, the unit starts searching all baud rates until it finds valid communication information.  Our AMX applications use a 'ping' (a data byte sent at regular intervals) to hold the unit in the configured baud rate.  In terminal emulator, the PC does not 'ping' the master port like Axcess does, so the unit will drop back into search mode.  The connection can be re-establish by hitting any key several times.  Alternately, you can set the Axcent 3 to stop searching by designating a specific baud setting.  The syntax for this command in terminal mode is: SEND COMMAND 0, 'SET BAUD 38400'

The command must be in CAPS and the desired rate can be from 300 to 115k or AUTO to return to autobaud mode.  The unit will return to autobaud mode if power is cycled.

To make sure the Axcent 3 always has the selected rate, include the statement in the DEFINE_START area of the Axcess code.
