The Moxa CP-118U and CP-138U Series are advanced 8-port Universal PCI serial boards designed for use in industrial automation systems, POS terminals, and ATMs. Supporting RS-232/422/485 (CP-118U) or RS-422/485 (CP-138U), they deliver excellent flexibility for connecting diverse serial peripherals.

With data rates up to 921.6 kbps and compatibility with both 3.3 V and 5 V PCI/PCI-X systems, these boards provide reliable performance. Their built-in 128-byte FIFO buffer, software/hardware flow control, and LED indicators ensure easy operation and troubleshooting. Isolated (-I) and wide-temperature models are also available for more demanding environments.
