The Moxa CP-134EL-A-I Series is a robust 4-port PCI Express serial board designed for demanding industrial automation, POS, and ATM systems. Supporting RS-422/485 standards, this board delivers secure and efficient data transmission with 4 kV surge protection and 2 kV electrical isolation, ensuring system integrity in harsh environments.

With a maximum baudrate of 921.6 kbps, 128-byte FIFO, and intelligent RS-485 functions like One-Click Installation and One-Click Troubleshooting, it simplifies setup and diagnostics. Built-in LEDs show the Tx and Rx status of each port. The low-profile design fits compact PCs, making it ideal for space-constrained systems.
