ACRCOMM MODULE JUMPERS (OPTIONAL)
Autobaud Detect Jumper (J7)
This jumper enables or disables the autobaud detect feature of the serial communications
channels on the ACRCOMM module. This jumper works in conjunction with the COM1
Startup Mode (P7013) and COM2 Startup Mode (P7029) parameters listed in the
ACR2000/ACR8000 User’s Guide under Miscellaneous Parameters P6912-P7029.
When the Startup Enable bit is not set (0 - default) in the COM1/2 Startup Mode
parameters, the jumper is ignored and Autobaud detect is always enabled. The default
operation of the COM1 and COM2 ports is Autobaud Detect enabled.
When the Startup Enable bit is set (1) in the COM1/2 Startup Mode parameters, the
jumper defines the Autobaud Detect function as listed in the following table.
