Product information

Description

Sunix SER6437AL is an internal RS-232 interface card that installs into a PCIe slot to add or expand two serial COM ports on PC-based systems. The board supports data rates up to 115.2 Kbit/s, uses a 128-byte FIFO buffer and is compatible with common PCIe lane widths. Its compact 65 × 68 mm form factor and low-profile bracket design suit installation in industrial PCs, embedded systems and standard desktop chassis where legacy serial connectivity is required.

Advantages

The SER6437AL provides reliable serial communication with a 128B FIFO to reduce CPU overhead and improve data throughput. Compliance with PCI Express Base Specification Revision 2.0 and support for multiple PCIe lane configurations (x1, x2, x4, x8, x16) ensure broad motherboard compatibility. Onboard SUN2212 UART controller and 16C950-compatible features deliver stable UART functionality and configurable stop bits (1, 1.5, 2). Certifications including CE, FCC, VCCI and BSMI indicate regulatory conformity for international deployments.

Suitable for

Industrial automation systems requiring reliable RS-232 ports
Embedded systems and single-board computers needing serial expansion
Point-of-sale, laboratory and legacy equipment integration
Applications where low-profile or compact expansion cards are required

How to use

Install the SER6437AL into an available PCIe slot (x1/x2/x4/x8/x16) on the host motherboard, secure the card with the bracket and connect required external devices to the RS-232 COM ports. After physical installation, power on the system and install appropriate drivers provided by the system vendor or Sunix to enable UART functions. Configure serial parameters (baud rate up to 115.2 Kbit/s, data bits, parity, stop bits) in the operating system or application to match connected serial devices.

Usage recommendations

For stable operation in industrial environments, use shielded serial cables, ensure proper grounding of the host system, and select driver versions that match the operating system. When integrating legacy equipment, verify baud rate and stop bit settings to avoid communication errors. Choose the low-profile bracket when installing in slim chassis to ensure proper fit.
