MODE
The MODE command is a special command used to switch the functionality of
the adapter. For ThermArray mode, use the following command to ensure the
correct configuration:
MODE 1CR
The adapter should respond with “RST Thermarray” to indicate proper
communication. Lack of response indicates a communication problem.

BAUD
The BAUD command is a special command used to change the RS232 COM
port baud rate. The adaptor will need to be switched into a different mode in
order to use the BAUD command. The following lists the sequence required to
change the baud rate.
1
MODE 1CR,
2
BAUD<baud rate>CR,
3
The supported <baud rate> is either 115200 or 9600.
