Product Description

DT-5019 is a universal converter of USB 2.0 to RS485/RS422, which is without addition power supply, compatible with USB, RS422, RS485 standards. It can convert USB signals to a balanced differential RS422 or RS485 signals. Each line has surge protection, and various surge voltage protections. The tiny capacitance distance guarantees RS422 / RS485 interface of high-speed transmission. RS422, RS485 connect by RJ45 and DB9 interface.

Converter with zero delay automatic transceiver inside, unique I/O circuit automatically control data flow direction, without any handshake signals (such as RTS, DTR,etc.) and jumpers set realize full-duplex, half-duplex mode conversion, plug and play. Ensure the product fix for all existing communication software and hardware interface.

DT-5019 converters for point-to-point, point-to-multi point reliable communications. Provides the point to more each converter allows connecting 32 RS422 or RS485 devices, data rate of 300 to 921600bps. The power and data flow indicator light will show fault if any breakdown. Support of communication has USB to RS422, USB to RS485.

Features

1. Point-to-point / 4-line full-duplex.

2. Point-to-multi point / 4-line full-duplex.

3. Point-to-point / 2-line half-duplex.

4. Point-to-multi point / 2-line half-duplex.

When the convertor is working at full-duplex or half-duplex, needs to add a matched resistance to avoid reflects and disturbance of signal. ( 120Ω, 1/4W).
