TOPAZ REP-RS485/RS485-Pr Interface Repeater

The repeater has two operating modes: interface converter and interface repeater. In the interface converter mode, the device is designed for connecting a network of devices with the half-duplex RS-485 inteface to devices with the RS-422 interface. In the repeater mode, the device amplifies signals of the half-duplex RS-485 interface and creates an RS-485 network comprising more than 128 devices.
