Introduction
The CP-114EL Series of smart, 4-port PCI Express boards designed for POS and ATM applications are a top choice of industrial automation
engineers and system integrators, and support many different operating systems, including Windows, Linux, and UNIX. In addition, each of the
boards’ 4 RS-232/422/485 serial ports supports a fast 921.6 kbps baudrate. The CP-114EL Series provides full modem control signals to ensure
compatibility with a wide range of serial peripherals, and their PCI Express x1 classification allows the boards to be installed in any PCI Express
slot.
Smaller Form Factor
The CP-114EL Series uses low-profile boards that are compatible with any PCI Express slot. The boards require only a 3.3 VDC power supply,
which means that the boards fit any host computer, ranging from shoebox to standard-sized PCs.
Drivers Provided for Windows, Linux, and UNIX
Moxa continues to support a wide variety of operating systems, and the CP-114EL Series is no exception. Reliable Windows and Linux drivers are
provided for all Moxa boards, and other operating systems, such as WEPOS, are also supported for embedded integration.
