13.4.31
If unable to establish communication in the HART over RS-485 mode, the HMA can be
reset to normal Modbus operating mode by switching DIP switch 1 to OFF. The HMA will
switch into the default communication mode. Using Procedure 1, set register 3008 to 0.
The HMA can be used either in that mode, or by setting DIP switch 1 to ON it can be used
in its normal Modbus configuration mode.
