RS232 to RS485 Converter

RS232 to RS485 Converter

RS232 to RS485 converters provide conversion between serial networks and other media. They can transparently convert RS232 signals to RS485 signals, as well as convert RS485 to RS232 signals without changing the PC’s hardware or software. The serial media converter lets you easily build an industrial grade, long distance communication system with standard PC hardware. Built-in 120Ω terminator for system reliability and easy installation.

It also works as Slave address decoder.

It has ARM cortex-M0+ controller where you can easily save the slave address using 7-pin DIP switch settings. The Slave address decoder is specifically meant for use in Data Concentrator Unit (DCU) where it is a common place to connect multiple slaves to the DCU. Slave address decoder sits between the Slave and the DCU. It acts as the gateway to the slave giving access control based on the address stored in the controller in slave decoder. It provides LED indication for data transmission and reception. Industrial grade enclosed in a rugged & rustless housing.
