Step3: Modbus network - Serial / Ethernet port connection
The GW-7238D can communicate both Modbus TCP and Modbus
RTU to J1939 at the same time. In Modbus RTU communication, it is
recommended to use only one serial port (RS-232 or RS-485) of the
gateway at the same time.
The following figures describe the COM, Ethernet and Power port
connections.
Figure 5-4: COM, Ethernet and Power port connections of GW-7238D
Step3: Power port connection
Connect the power supply to the GW-7238D module's power terminal
connecter; please see as Figure 5-4.
Step5: Connect to GW-7238D
When in the first connection, the controller may run the Serial
network at 115200 baud with none parity, 1 stop bit and 1 Net ID; or run
the Ethernet network and set on the same subnet to connect via IP
address(192.168.255.1) shown as below figure. After the first connection,
it should follow the GW-7238D Modbus connection settings to change.
