baud rate, parameter 201: Baudrate must be selected. And to read/change the parity parameter 335:
Bus1 Parity must be selected. To change one of these parameters parameter 7: Initreset has to be set to
‘64’ first.
Valid values for the slave address are between 1 and 247, valid values for the baud rate are 9600, 19200
and 38400, valid values for parity are 0 (= None), 1 (= Odd) and 2 (= Even). The changed values will be
effective immediately after changing.
In case of OEMD2 hardware revision (“OEMD2” text on the instrument label):
