Product information

Description

The EXSYS EX-44342 Internal Serial interface card provides two high-performance RS-232 serial ports using 16C550-type UARTs and connects to a host system via a PCI-Express (PCIe) slot. Designed for PCs, thin clients and servers, the compact card (66 mm × 65 mm) enables reliable COM port expansion and supports standard serial settings including 5/6/7/8 data bits and 1/1.5/2 stop bits. The card is PCI-Express Plug-and-Play compatible and avoids manual IRQ or I/O address configuration. It also supplies +5V and +12V on pin 9 of the male connector for POS system power.

Advantages

The EX-44342 offers instant COM port expansion via PCIe with automatic Plug-and-Play detection, two independent RS-232 ports with 16C550-compatible UARTs for broad legacy-device compatibility, and a compact form factor suitable for standard and small cases when paired with the included Low Profile bracket. Pin 9 power output supports POS peripherals without separate power wiring.

Suitable for

Connecting legacy serial devices such as barcode scanners, receipt printers and modems
POS systems requiring serial ports with pin 9 power
Industrial or embedded PCs, thin clients and servers needing additional COM ports

Key specifications

Model: EXSYS EX-44342
Interface: PCI-Express (PCIe) host interface
Ports: 2 × RS-232 serial ports (16C550-type UART compatible)
Serial settings: data bits 5/6/7/8; stop bits 1/1.5/2
Power on connector: +5V and +12V available on pin 9 (POS support)
Form factor: internal card, dimensions 66 mm (W) × 65 mm (D)
Plug-and-Play: PCI-Express Plug-and-Play compatible

How to use

Install the EX-44342 into an available PCIe slot on the host motherboard, secure the bracket, and attach the serial devices to the male RS-232 connectors. The operating system should detect the card automatically via PCIe Plug-and-Play; install drivers if required by your OS. If using POS peripherals that draw power from pin 9, confirm that the connected device accepts power on that pin and does not exceed the provided voltage.

Usage recommendations

Use the included Low Profile bracket for small computer cases and verify driver compatibility with your operating system. For devices requiring powered RS-232, confirm power requirements before connecting to pin 9 to avoid damage.
