Product information

Description

The StarTech.com Serial Slot Plate is a 16-inch (40 cm) adapter designed to add an extra RS-232 serial port to your computer system via a rear expansion slot. Featuring a 9-pin serial male connector and a 10-pin motherboard header IDC connection, this internal interface adapter enables direct connection of legacy serial devices, industrial equipment, and point-of-sale peripherals to the motherboard.

Advantages

This serial slot plate provides a reliable internal connection for systems that require legacy serial port access without the need for an add-in controller card. Constructed from quality components, the adapter ensures stable signal transmission and durability for long-term use in various computing environments. Its compact 40 cm cable length allows for flexible routing inside standard computer chassis while utilizing an available rear expansion slot for clean integration.

Suitable for

  • Connecting legacy serial devices to modern motherboards
  • Interfacing with industrial equipment and machinery
  • Hooking up point-of-sale peripherals and receipt printers
  • Adding a DB9 serial port via a rear computer expansion slot

When it may not be suitable

This product is not suitable for computers that lack an available 10-pin internal motherboard serial header or an open rear expansion slot. It cannot be used to connect external USB or parallel devices, as it strictly supports RS-232 serial interface communication through an IDC connection.

Key specifications

  • Host interface: IDC
  • Output interface: Serial
  • Serial interface type: RS-232
  • Cable length: 16 inches (40 cm)
  • Connectors: 1 x 9-pin DB9 male, 1 x 10-pin motherboard header IDC female
  • Form factor: Rear expansion slot plate bracket
  • Product colour: Grey

How to use

Power off your computer and disconnect the power cord before opening the computer case. Locate an available 10-pin serial header on your motherboard and plug the IDC connector securely into the pins, ensuring correct alignment. Mount the metal slot plate bracket onto an open rear expansion slot of the computer chassis and secure it with a screw. Close the computer case, reconnect the power, and connect your RS-232 serial device to the external DB9 port.

What to consider before purchase

  • Verify that your motherboard has an available 10-pin serial header
  • Check that your computer case has an available rear expansion slot
  • Confirm your peripheral devices require an RS-232 serial interface connection

Ensure the computer is completely powered off and unplugged before performing any internal installation to prevent potential hardware damage.
