Two serial ports from a USB header

The ICUSB232INT2 adds two RS232 DB9 ports through a single 10-pin motherboard header. It draws power from the USB bus so no external supply is needed. The 24-inch cable reaches most internal routing paths. Legacy equipment and industrial gear connect directly without a separate expansion card.

Steady throughput with FIFO buffers

On-chip FIFO receive and transmit buffers smooth data flow during continuous transfers. COM-port retention keeps the same port assignments after reboots or driver reloads. The FTDI chipset sustains the rated 115200 bps without drop-outs. Bus power remains stable because the adapter draws only what the header provides.

Replaces add-in serial cards

This adapter removes the need for a PCI or PCIe serial card when a free USB header exists. The low-profile bracket fits slim chassis where full-height cards cannot. It is not suited for systems that lack an internal USB header or that require more than two serial ports.

Questions sur cet article

How much power does the ICUSB232INT2 draw when both serial ports are active all day?

The adapter is bus powered from the USB motherboard header, so it needs no separate supply and adds only a small load to the 5 V rail.

What motherboard header must be free to install this adapter?

A single 10-pin IDC USB header is required; the package includes a 24" cable and both low-profile and standard brackets for the two DB-9 ports.

Will the ICUSB232INT2 work with legacy equipment that expects 7 data bits and even parity at 115200 bps?

Yes — the FTDI chip supports 7 or 8 data bits, 1 or 2 stop bits, and none, odd, even, space or mark parity up to the full 115200 bps rate.
