6.2. Wiring Connection to the Modbus Module

Sometimes it is necessary to convert from the standard RS485 to RS232 for connection to a Personal Computer. The wiring between the Modbus module and the converter must be set as follows:

RS485 Converter	Modbus Module
TXA	RXA
RXA	TXA
TXB	RXB
RXB	TXB
SG	SG

Note: Different RS485 converters have different connections. For example, when one commonly available converter is used, TXA connects to RXB, TXB connects to RXA, etc. Please refer to the converter manufacturer’s instructions.
