The CP-118U-I and CP-138U-I are smart, 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 precision 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 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
8RS-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.
Top Serial Performance
Moxa's 20-plus years of experience in serial board design is now
concentrated in 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.
Drivers Provided for Windows, Linux, and Unix
Moxa continues to support a wide variety of operating systems, and
the CP-118U-I and CP-138U-I boards are no exception. Reliable Windows
COM and Linux/Unix TTY drivers are provided for all Moxa boards, and
other operating systems, such as WEPOS, are also supported for embedded
integration.
