What this adapter does

The StarTech PLATE9M16 connects a motherboard 10-pin IDC header to a DB-9 male serial port on a bracket plate. It adds a legacy COM port to the rear of a PC without using an expansion slot. The cable is 406 mm long and coloured grey. The assembly weighs 0.08 kg.

Critical connection detail

Connector A is a DB-9 male D-Sub; Connector B is a 10-pin IDC female header. Wiring follows the Apex10-Everex-Intel specification. No other pinout is supported. Verify your motherboard header matches this layout before ordering.

Who this suits, who it doesn't

Builders restoring serial connectivity on boards that still expose a 10-pin header will find this a direct fit. Systems lacking that header, or needing a different pin arrangement, cannot use this adapter. Buyers who want more ports or a USB alternative should look elsewhere.

Questions about this item

What does the 10-pin IDC connector actually connect to on my motherboard?

The 10-pin IDC female connector plugs directly into a standard motherboard serial header, routing the DB-9 signals through the 15.98 in cable to the rear bracket.

Does the Apex10-Everex-Intel wiring spec limit the serial signalling rate in any way?

The specification defines the pin-out between the DB-9 male and the 10-pin IDC header; it does not impose a maximum baud rate, so the port runs at whatever speed the motherboard UART supports.

How much clearance does the 406 mm cable need behind the expansion slot bracket?

The 15.98 in ribbon provides enough length to route from a bottom-row header to a full-height bracket without tension, adding only 1.10 lb to the assembly.
