Introduction
The GW-7228 is a solution that provides a protocol conversion between J1939 and Modbus RTU. For J1939 network, the GW-7228 supports PDU1, PDU2, broadcast and destination specific type of J1939 messages. From the view of Modbus RTU network, the GW-7228 is a Modbus RTU slave to reply the request from Modbus RTU master. We provide Utility software for users to configure the parameters of J1939 / Modbus RTU of the GW-7228. The application fields can be Diesel power-train applications, In-Vehicle networks for trucks and buses, etc.
The following figure shows the application architecture for the GW-7228
