The CP-138U-I is an 8-port serial board designed for long distance, multi-point, PC-based data acquisition applications. Industrial automation system integrators will be eager to use these boards for many of their industrial automation projects. RS-485 communication requires precise timing control to enable and disable the line driver, and the Moxa Turbo Serial Engine chip that powers the CP-138U-I board comes with on-chip ADDC (automatic data direction control) to make RS-485 as easy to use as RS-232. The CP-138U-I’s 8x RS-422/485 ports can achieve data rates up to 921.6kbps, and in RS-485 mode, one serial port can connect up to 31x daisy-chained RS-485 devices within a range of 1.2km. In addition, the 2kV electrical isolation protection on the CP-138U-I board helps prevent equipment damage for long distance RS-485 communication. With 20-plus years of experience in serial board design, Moxa is now concentrating on a new high performance serial data transmission chip. The Turbo Serial Engine chip provides serial boards with a 128-byte FIFO, on-chip hardware and software flow control, and burst data mode. Thanks to the Turbo Serial Engine, Moxa is able to offer the world’s best performing smart serial boards. Moxa continues to support a wide variety of operating systems, and the CP-138U-I board is no exception. Reliable Windows COM and Linux/Unix TTY drivers are provided for most Moxa boards, and other operating systems, such as WEPOS, are also supported for embedded integration.
