2CH-HUB-RS485 is an industrial-grade caching RS485 hub/splitter with two masters and one slave or one master and two slaves.

Two modes are used for scenarios where two RS485 hosts read data from one RS485 slave and one RS485 host reads data from two RS485 slaves. Adopting a rail-type installation, easy to install, compact in size, and terminal-type power supply connection.

Simple configuration, stable and reliable, adaptable to multiple standard baud rates and other serial port parameters, supporting three separate serial port settings. At the same time, it also supports address filtering function, which can help users filter out unnecessary data.
