## Summary description

Sunix SER5027AL is a PCI Low Profile serial adapter providing RS-232 connectivity. Designed as a single-port serial interface card, it installs into a PCI slot (low profile) to add legacy serial communication to desktop systems, industrial PCs or embedded applications. Suitable for connecting modems, POS devices, industrial controllers and other RS-232 equipment.

## Long description

The Sunix SER5027AL PCI Low Profile serial adapter provides a single RS-232 port for adding legacy serial connectivity to desktop systems, industrial PCs and embedded applications. The card is designed to fit a low-profile PCI slot and delivers a standard DB9 RS-232 interface for connecting modems, point-of-sale peripherals, industrial controllers and other serial devices. The adapter supports the common serial signaling and voltage levels expected by RS-232 equipment and is intended for systems that require a reliable physical serial connection without changing existing software that uses serial COM ports.
Advantages
The adapter occupies a single low-profile PCI slot and exposes one standard RS-232 port for easy integration into space-constrained systems. It provides a straightforward hardware solution to restore or add serial ports on modern motherboards that lack legacy connectors. The card is compatible with common serial devices and supports stable physical connection and signal levels required for industrial and consumer RS-232 peripherals.
Suitable for
 Connecting modems and serial communication devices
 Point-of-sale terminals, barcode scanners and receipt printers with RS-232 interfaces
 Industrial controllers, PLCs and automation hardware requiring serial links
 Embedded systems and legacy applications that rely on COM port communication
Key specifications
 Interface: PCI low profile card
 Serial standard: RS-232 (single port)
 Connector type: DB9 male serial connector
 Form factor: Low profile bracket suitable for compact chassis
 Typical use: Single-port serial communications for data exchange and device control
How to use
Install the card into an available low-profile PCI slot on the host motherboard and secure the bracket to the chassis. Connect the RS-232 device to the DB9 port using a standard serial cable. Power on the system and, if required by the operating system, install drivers or let the OS enumerate the new serial port. Configure the serial port settings (baud rate, data bits, parity, stop bits and flow control) in the host application to match the connected device’s communication parameters.
Usage recommendations
Use short, shielded RS-232 cables for reliable signal integrity, especially in electrically noisy or industrial environments. Verify and match serial parameters on both ends before data exchange. If using in a compact chassis, confirm the low-profile bracket orientation and clearance prior to installation.
