The Moxa CP-118EL-A is an 8-port PCI Express serial card designed for use in industrial systems, point-of-sale applications, and automation applications. The card features a compact low-profile form factor, making it suitable for space-constrained systems such as mini-PCs and industrial computers. Each of the eight serial ports can be independently configured for RS-232, RS-422, or RS-485, supporting both 2-wire and 4-wire modes. The maximum data transfer rate is 921.6 kbps, with support for non-standard baud rates. The integrated 128-byte FIFO buffer, along with support for hardware and software flow control (RTS/CTS, XON/XOFF), ensures reliable data transmission. The card provides full modem control signals (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND) and is compatible with any PCI Express slot (x1 compatible).

Applications include industrial automation systems, POS terminals, and ATM devices, where stable and reliable serial communication with multiple peripheral devices is required. The card is designed for continuous operation in industrial environments and features a high MTBF of 1,359,482 hours, indicating long service life and low failure probability. Integrated LEDs for transmit (Tx) and receive (Rx) per port facilitate diagnosis and maintenance, as status information can be read directly on the device.

Functions and features in detail include support for various data formats: data bits can be set to 5, 6, 7, or 8, stop bits to 1, 1.5, or 2, and parity options include None, Even, Odd, Space, and Mark. Power consumption is 1.285 mA at 3.3 VDC, representing low energy usage. The mechanical form factor is low profile with dimensions 68.9 x 88 mm. The card is designed for operating temperatures from 0 to 55 °C, with storage temperatures from -20 to 85 °C and humidity from 5 to 95 % (non-condensing).

Technology explained simply means the card features a VHDCI 68-pin connector used for connecting to external serial devices. The FIFO buffer stores data packets to prevent transmission delays or data loss at high data rates. Flow control prevents the receiver from being overloaded by temporarily halting data transmission when the receiver is not ready. Modem signals enable control of external devices via the serial interface.

Compatibility and accessories include support for various operating systems: Windows (95 to 10, Server 2019, Embedded CE/XPe), Linux (Kernel 2.4.x to 5.x), and UNIX (Solaris 10, UnixWare 7, SCO OpenServer 5/6). Optional accessories include cables such as CBL-M68M9x8-100 (VHDCI 68 to 8 x DB9, 1 m) and CBL-M68M25x8-100 (VHDCI 68 to 8 x DB25, 1 m). Adapters such as the Mini DB9F-to-TB (DB9 female to screw terminal) and breakout boxes (OPT 8B+, OPT 8A+, OPT 8S+ with surge protection, OPT8-M9+, OPT8-RJ45+) can be used to expand connection options.

Installation and mounting is done by inserting the card into a PCI Express slot (x1 compatible). The card is designed for use in standard PCs and industrial computers. Installation is guided by the included quick installation guide, which describes the necessary setup steps. The warranty card is also included in the delivery scope.

Operational advantages include high reliability, long service life (MTBF over 1.3 million hours), and flexibility in configuring the serial ports. The integrated LEDs enable quick fault diagnosis, and support for multiple operating systems increases deployment flexibility. The card is designed for continuous industrial use and complies with standards CISPR 32, FCC Part 15B, IEC 61000-4-2 to -4-8, EN 55032/35, as well as RoHS, CRoHS, and WEEE. Conformance to Telcordia TR/SR standards ensures product quality and reliability.

The delivery scope includes the CP-118EL-A serial card, a quick installation guide, and a warranty card. The card is designed for industrial environments and provides stable and reliable serial communication with multiple devices via a PCI Express slot.
