DIP switch setting instructions (as shown above):
1 DIP switch Bit1-6(A0-A5): Set the Slave Address(RS485 Address) of the Modbus command

2 DIP switch bit7(SW1): Ethernet and RS485 port transparent transmission function. If you need to use this board as an RS485 Ethernet server, please turn SW1 to the ON position.

2 DIP switch bit8(SW2): When SW1=ON, SW2=ON can only transparently transmit Ethernet and RS485 data, and cannot control this board.

Typical application 1: Control the board through the Ethernet port (network port parameters need to be set)

Typical application 2: Control the board through RS485 port

Typical application 3: As an Ethernet to RS485 serial port server, controlling ordinary RS485 IO through Ethernet


1 Set the DIP switch SW1 to ON

2 Refer to the folder ''Network port parameter settings'' to set the network port parameters (baud rate 115200BPS)

3 Set the RS485 serial port parameters, refer to the
''ETROA01_ETROB02_ETAIC04_ETVOD08_ETIOE16 instruction manual''
Default baud rate ''9600 N 8 1''
