AN-RS-485-MOD 1 port Mobdus gateway / converter


Modbus is an industry adopted communication protocol that is based on RTU, ASCII, and TCP protocols for various of applications; these three rotocols are commonly used by a lot of equipments in the industry, such as DCS, PLC, HMI, power meters, various sensors and measuring instruments. AN-RS-485-MOD series supports the standard Modbus protocol and is capable of converting the Modbus protocols between Modbus RTU/ASCII (Master) to Modbus TCP (Slave). It’s a simple and cost effective Modbus Gateway. AN-RS-485-MOD series which supports the three most commonly used serial communication interfaces, RS-232, RS-422 and RS-485. It also provides a web-based configuration UI, so the users can select the serial interface easily.
