ICPDAS GW-7228-G J1939/Modbus RTU Slave Gateway

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. Features Built-in jumper to select 120 ohm terminal resistor Watchdog inside Transmission and reception of all types of J1939 messages, including PDU1, PDU2, broadcast and destination specific J1939 Transport Protocol for transmission and reception of large messages (9 - 1785 bytes) Support BAM of Connection Management Message Network addresses management Support Modbus RTU slave protocol Configurable for Modbus Network ID(1~250)
