How to use

Install the PCI Express x1 Card into an available PCIe x1 slot on the host motherboard following standard anti-static procedures. Attach the included low profile bracket if installing into a Mini-PC or small form factor case. Connect external serial devices to the RS-232 ports using appropriate DB9 cables. Configure device settings and serial parameters (baud rate, parity, data bits, stop bits) in the operating system or application to match the connected devices.

Recommendations

Use correct cabling and confirm pinout compatibility before enabling the optional 5 V or 12 V supply on the RS-232 pins. Do not exceed the power ratings of connected devices and ensure proper driver installation for the host operating system.
