Product information

Description

The StarTech.com 40cm Serial Slot Plate provides a practical solution for adding a reliable COM port to your computer system. Featuring a 9-pin male DB9 connector on one end and a 10-pin IDC motherboard header on the other, this internal expansion bracket connects directly to your motherboard to deliver an RS-232 serial output. Designed to support legacy hardware integration and specialized industrial equipment, this cable adapter allows you to maintain functionality with older serial devices without requiring external converter boxes.

Advantages

This serial slot plate offers a straightforward and cost-effective way to expand your system connectivity using existing internal motherboard headers. The high-quality construction and durable materials ensure stable signal transmission and long-term reliability for demanding environments. Measuring 40cm in length, the cable provides sufficient reach for standard computer chassis configurations while helping to maintain clean internal cable management. Compliance with CE and REACH standards ensures that the product meets environmental and safety regulations.

Suitable for

  • Connecting legacy serial peripherals to modern computer systems
  • Integrating industrial automation and control equipment
  • Establishing communication with scientific instruments and POS terminals
  • Adding a COM port via internal motherboard headers

When it may not be suitable

This adapter is not compatible with motherboards that lack a standard 10-pin serial IDC header. It is also unsuitable for systems that require external USB-based serial conversion or higher-voltage communication standards outside the scope of standard RS-232 serial output.

Key specifications

  • Host interface: IDC 10-pin
  • Output interface: Serial RS-232
  • Connector 1: 9-pin male DB9
  • Connector 2: 10-pin IDC female
  • Cable length: 40 cm
  • Product colour: Grey
  • Internal placement: Yes

How to use

Power down your computer and disconnect the power cord before opening the chassis. Locate an available expansion slot on the back of your computer case and remove the metal slot cover. Plug the 10-pin IDC connector of the slot plate directly into the corresponding serial header on your motherboard, ensuring correct pin alignment. Secure the metal bracket to the computer case using the chassis 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 features an available 10-pin IDC serial header
  • Check the physical dimensions of your computer case to ensure standard expansion slot compatibility
  • Confirm that your external peripherals utilize standard RS-232 serial communication

Usage recommendations: Always handle internal computer components with care and follow standard anti-static precautions during installation. Ensure the system is completely powered off before attaching the cable to the motherboard header.
