‘[R1’ Command — Read 20mA Trim Value
This command is sent by the master to request the STXplus to send the 20mA trim value. The
trim value is used to calibrate the current output engine at the 20mA point. The range of
acceptable values is 0-65535. The default value is 59,674. For this example, the master requests
the 20mA trim value for an STXplus at address 01 which returns 59611 and a checksum of 66.
