P131 Protocol
This parameter is used to determine what Modbus protocol is being used.
OPTION
DESCRIPTION
0 = Modbus RTU (Default)
Protocol used is Modbus RTU
1 = Modbus ASCI
Protocol used is Modbus ASCI
P132 Device Address
This is the Modbus slave address of the Ultra 4. Default = 126
P133 Device Baud Rate
Sets the speed of the RS485 digital communications interface to match that
of the device it is communicating with. Default = 19200
P134 Parity

DESCRIPTION
0 = Unsigned Integer
(Default)
16 bit which contains values from 0 – 65335
1 = Signed Integer
16 bit which contains values from -32768 to
+32768.
2 = Float Modicon
This is an order in which the most significant
value in the sequence is stored first.
3 = Float IEEE
This is an order in which the least significant
value in the sequence is stored.
