Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range, and networking capabilities. The RS-422 and RS-485 standards overcome those limitations by using differential voltage lines for data and control signals. The BSC3123i converter lets you to take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. They transparently convert RS-232 signals to RS-422 or RS-485 signals. You do not need to change your PC's hardware or your software. The BSC3123i lets you easily build an industrial grade, long distance communication system with standard PC hardware. They extend the communication distance by 1.2km (4kft) or increase the maximum number of connected nodes by 32. The BSC3123i also provides the optical isolation for system protection.
