Diverse Hardware Infrastructure The MB5202 Modbus Gateway supports the four most commonly used communication standards, RS-232, RS-485, RS-422, and Ethernet. It comes with a user-friendly configuration utility to allow quick hardware interface selection, so you can easily connect to your existing communication infrastructure. And with industrial EMC protection plus a wide operation temperature range, MB5202 is ready for every mission.

Switching between Modbus Protocols MB5202 supports the Modbus protocols and is capable of conversion between Modbus TCP, Modbus RTU, and Modbus ASCII for all supported hardware interfaces.

Modbus ID Routing Besides various types of hardware communication interfaces and Modbus protocol conversion, MB5202 also supports Modbus ID routing. Therefore, it can integrate your existing and complex Modbus hardware configuration into a simple network for easy management.
