The Moxa CP-118E-A-I and CP-138E-A-I series are high-performance 8-port PCI Express serial boards designed for use in industrial automation, POS, and ATM applications. Supporting RS-232/422/485 (model dependent), these boards feature intelligent RS-485 technology for hassle-free installation and troubleshooting.

With data rates up to 921.6 kbps, 4 kV surge protection, and 2 kV isolation, they ensure robust performance in harsh environments. The boards are compliant with PCI Express 1.0 and fit into any PCIe x1 slot. Built-in per-port LEDs and a wide range of driver support make integration easy across Windows, Linux (including ARM platforms), and UNIX systems.
