SIIG, Inc JJE20611S1 RS-232 1S PCIe laptop add-on card 250Kbps

SKU CH-YB9N-GGJK7 MPN JJE20611S1

Adds a single 16C650 UART serial port with 250Kbps transfer rate to PCIe desktop systems

  • Adds a 16650 RS-232 serial port to PCIe systems
  • Supports up to 250 Kbps data transfer rate
  • Configurable 5 V or 12 V power output for peripherals
  • Includes both full-height and low-profile mounting brackets
  • Compliant with PCI Express 2.0 Gen 1 specification

PCIe RS-232 serial card

This PCIe x1 card adds a single 16C650 UART serial port to a desktop computer. It provides a standard 9-pin RS-232 interface for connecting legacy peripherals. The board fits any PCI Express slot regardless of lane width. It is suited for industrial, point-of-sale and instrumentation users who need a native serial connection.

250 Kbps throughput with 256-byte FIFO

The port supports data rates up to 250 Kbps and handles 5 to 9-bit formats with multiple parity options. On-chip 256-byte FIFO buffers smooth transmit and receive streams. Hardware and software flow control are both available. Bandwidth is adequate for typical POS, scanner and printer traffic but will not serve high-speed data-acquisition needs.

Dual-profile bracket with jumper power

Included low-profile and full-height brackets let the card install in either chassis type. Jumpers configure the port to supply 5 V or 12 V power for devices such as handheld scanners or POS displays. The controller complies with PCI Express 2.0 and PCI Bus Power Management 1.2. No external power cable is required.

Questions about this item

Will this PCI Express 2.0 Gen 1 x1 card work in my older PCIe 1.0 or 2.0 desktop slots?

Yes, the single-lane PCIe 2.0 Gen 1 interface is backward compatible with PCIe 1.0 and 2.0 slots of any lane width, so it will function in older desktop motherboards.

How can I verify the 16C650 UART is running at the full 250Kbps after installation?

Check Device Manager to confirm the port appears as a 16C650 UART, then use a terminal program to test a loopback connection at 250Kbps with hardware flow control enabled.

Does the box include both full-height and low-profile brackets for my chassis?

The dual-profile design ships with both a standard full-height bracket and a low-profile bracket, so no separate bracket purchase is needed for either chassis type.
