## Long description

The EXSYS EX-44064 Internal Serial Interface Card is a PCIe I/O adapter that provides four RS-232 serial ports based on the 16C1050-compatible UART. Designed for installation in desktop PCs, thin clients or servers, the card expands available COM ports via a PCI-Express slot and supports automatic Plug-and-Play configuration without manual IRQ or I/O address settings. The connector supplies +5V and +12V on pin 9 to support POS devices that require power over the serial connection.
Advantages
The EX-44064 offers reliable legacy serial connectivity with high-performance 16C1050-type UART compatibility, ensuring stable data transfer and broad device support. Its PCIe host interface provides straightforward installation with automatic configuration, eliminating IRQ and I/O conflicts. The card is CE and FCC certified, and its small form factor (87.4 mm × 66.7 mm) makes it suitable for a range of system chassis.
Suitable for
Connecting legacy RS-232 devices such as barcode scanners and receipt printers
Expanding COM ports in industrial PCs, thin clients and servers
Point-of-sale (POS) systems that require +5V/+12V on pin 9
