EXSYS EX-41384 Κάρτα σειριακή PCI 4 θυρών RS-232 με βραχίονα low-profile

The EXSYS EX-41384 stands out by offering four independent RS-232 ports on a single PCI card, each with a 128-byte FIFO buffer and data rates up to 921.6 Kbps. This makes it a practical choice for industrial PCs, point-of-sale systems, or any setup that needs multiple legacy serial devices without sacrificing a slot per port.

Highlights

• Four RS-232 serial ports via a single PCI slot
• 16C950 compatible UART with 128-byte FIFO per port
• Supports data rates up to 921.6 Kbps
• Includes low profile bracket and fan-out cable (HD44 to 4x DB9 male)
• Works with 3.3V and 5V PCI buses

In daily use

The card installs in any standard PCI slot and provides four DB9 male connectors through the included fan-out cable. Hardware and software flow control, configurable data bits (5-8), stop bits (1, 1.5, 2), and parity options (even, odd, none, mark, space) ensure compatibility with a wide range of serial peripherals. IRQ sharing reduces resource conflicts in multi-card systems. The low profile bracket allows installation in slim desktop or rackmount chassis.
