CP-134U-I-DB9M

Moxa's CP-134U-I Series serial port multiplexer cards are designed for long-distance, multipoint PC-based industrial automation systems. Automatic Data Direction Control for precise on-board RS-485 communication requires precise time control for turning the line driver on and off. The Moxa Turbo Serial Engine chip that powers the CP-134U card is supplied with ADDC® and enables RS-485 to be used as easily as RS-232. Each of the 4 RS-422/485 serial ports on the cards has a data rate of 921.6 Kbps. In RS-485 mode, 31 daisy-chained RS-485 devices within 1.2 km can be added to the serial port. The CP-134U-I model has 2 kV optical isolation for long distance RS-485 communication. Windows COM and Linux/Unix TTY drivers are provided for all Moxa cards and other embedded operating systems such as WEPOS.
