EXSYS EX-40032 2-poorts RS-232 ISA seriële adapterkaart

Legacy industrial machines, point-of-sale terminals, and specialized data-acquisition gear often rely on RS-232 serial connections, but modern PCs no longer include these ports. The EXSYS EX-40032 solves that problem by adding two genuine RS-232/V.24 serial ports through a standard 16-bit ISA slot, restoring full compatibility with your existing serial devices.

Who is it for

System integrators and technicians maintaining older industrial PCs, POS systems, or laboratory equipment that still run DOS, Windows 95/98/NT/2000/XP, or Linux. It is ideal for adding serial connectivity to legacy ISA-based computers without replacing the whole system.

Main features

• Two RS-232/V.24 serial ports via 16C550-compatible UARTs with 16-byte FIFO buffers
• 16-bit ISA bus interface, jumper-selectable I/O addresses and IRQs
• Data transfer rates up to 115.2 Kbps per port
• Two DB9 male connectors on the card bracket
• Powered directly from the ISA bus, no external power supply needed

Specifications

• Bus interface: ISA (16-bit)
• Serial standard: RS-232, V.24
• Number of ports: 2
• UART chipset: 16C550 compatible
• FIFO buffer: 16 bytes per port
• Maximum data transfer rate: 115.2 Kbps
• Connectors: 2x DB9 male
• I/O address and IRQ: jumper-selectable
• Operating system support: DOS, Windows 95/98/NT/2000/XP, Linux
• Form factor: Standard ISA card

Tips

Before installation, check your system BIOS for available ISA resources and disable any conflicting onboard serial ports. Use the included jumpers to set unique I/O addresses and IRQs for each port. For DOS or Windows 95/98, install the drivers from the manufacturer's website; Linux kernels 2.4 and later usually detect the card automatically.
