I-7520, ICP DAS USA Ethernet Media Converter

ICP DAS USA RS-232 to RS-485 Converter

The ICP DAS USA RS-232 to RS-485 converter with auto-tuning function and auto-switching baud rate. It is made of fire-retardant materials. However, RS-232 has limited transmission speed, communication range, and networking capabilities. The RS-485 standard overcomes these limitations by using differential voltage lines for data and control signals that converts RS-232 signals into isolated RS-485 signals, eliminating the need to change any hardware or software. It lets you easily build an industrial grade, long-distance communication system using standard PC hardware. It has 1 input and 1 output.
