Industrial automation system integrators will be eager to use these boards for many of their industrial automation projects. On-chip ADDC® for precise RS-485 communication 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-118U-I and CP-138U-I boards come with on-chip 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- Moxa continues to support a wide variety of operating systems, and the CP-118U-I and CP-138U-I boards are no exception. Reliable 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. Windows and Linux/Unix drivers are provided for most Moxa boards, and other operating systems, such as WEPOS, are also supported for embedded integration. ADDC® (automatic data direction control) to make RS-485 as easy to use as RS-232. RS-485 multidrop for up to 31 devices within 1.2 km The CP-118U-I’s 8 RS-232/422/485 ports and the CP-138U-I’s 8 RS-422/485 ports can achieve data rates up to 921.6 kbps, and in RS-485 mode, one serial port can connect up to 31 daisy-chained RS- 485 devices within a range of 1.2 km. In addition, the 2 kV electrical isolation protection on the CP-118U-I and CP-138U-I boards helps prevent equipment damage for long distance RS-485 communication. › ›Over 700 kbps data throughput for top performance › ›921.6 kbps maximum baudrate for super fast data transmission › ›128-byte FIFO and on-chip H/W, S/W flow control › ›Compatible with 3.3/5 V PCI and PCI-X › ›Drivers provided for a broad selection of operating systems, including the latest Windows and Linux › ›Easy maintenance with on-board LED display, and management software › ›Wide temperature model available for -40 to 85°C environments Hardware Comm.
