F. CONFIGURATION BITS
Address 40001 contains configuration bits sent from the BAS to the appliance. These bits tell the appliance to use its own internal
inputs, or inputs from the BAS. When a bit is set to 1, the appliance will ignore the corresponding value contained internally and expect
the BAS to write that value into the holding registers.
The configuration bits are as follows:
