CP-118U-I/CP-138U-I

8-port RS-232/422/485 Smart Universal PCI Serial Board w/ 2 KV Optical Isolation

The CP-118U-I and CP-138U-I smart, 8-port serial boards are designed for long distance, multi-point, PC-based data acquisition applications. Industrial automation system integrators will be eager to use this board for many of their industrial automation projects.

On-chip ADDCTM for Precision RS-485 Communication
RS-485 communication requires precise timing control to enable and disable the line driver, and the MOXA Turbo Serial EngineTM chip that powers the CP-118U-I and CP-138U-I card comes with on-chip ADDCTM (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, the serial port can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km. For long distance RS-485 communication, 2 KV optical isolation protection is available to prevent equipment damage.
