CP-118U-I
CP-118U-I/138U-I
The CP-118U-I and CP-138U-I are 8-port serial boards 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.
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 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.
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 optical isolation
protection on the CP-118U-I and CP-138U-I boards helps prevent
equipment damage for long distance RS-485 communication.
