Detailed Product Description

TRP-C08  

TRP-C08 USB to RS-232/422/485
Isolated Converter

Introduction
The TRP-C08 allows you to connect your serial devices to systems by using a USB interface. With auto configuration in data format, baud rate and RS-485 data flow direction control. TRP-C08 is able to automatically configure RS-232, RS-422 or RS-485 signals to baud rate without external switch setting. TRP-C08 is equipped with 3000V DC of isolation and internal surge-protection on each data lines to protect the host computer and converter against high voltage spikes, as well as ground potential difference. TRP-C08 also features a high-speed 256 Kb/s transmission rate, and supports various O.S. The industry DIN rail and panel mounting design enable user a fast and professional installation.
