The Moxa CP-118E-A-I and CP-138E-A-I Series are robust 8-port PCI Express serial boards designed for industrial automation, POS, and ATM systems. Both models feature 2 kV electrical isolation and 4 kV surge protection, ensuring stable performance in harsh environments.

The CP-118E-A-I supports RS-232, RS-422, and RS-485 interfaces, while the CP-138E-A-I is focused on RS-422/485 applications. Both models include DIP switch configuration and Moxa’s Intelligent RS-485 features like One-Click Installation and Troubleshooting for quick and easy setup.

With a maximum baudrate of 921.6 kbps and a 128-byte FIFO, these boards support high-speed communication. They are fully compatible with major operating systems, including Windows, Linux (also ARM-based), and UNIX, and can be paired with optional breakout cables and adapters for flexible deployment.
