EXSYS EX-3608 2-Port RS232 Serial PCI Express x1 Card

The EXSYS EX-3608 is a PCI Express x1 expansion card that adds two RS232 serial ports with high-speed data transfer up to 921.6 Kbps per port. Based on the MosChip MCS9901 chipset, it provides reliable serial connectivity for industrial and legacy devices.

Advantages

Each port features a 128-byte FIFO buffer to reduce CPU load and prevent data loss during high-speed communication. The card supports hardware and software flow control, ensuring stable data exchange with a wide range of serial peripherals. ESD protection up to 15KV safeguards the card against electrostatic discharge, enhancing durability in demanding environments.

Suitable for

• Connecting legacy RS232 devices such as barcode scanners, POS terminals, and industrial machinery
• Systems with limited serial ports that require additional COM ports
• Industrial automation and control applications
• Point-of-sale and retail environments
