Digi International

Digi International AccelePort Xe 4-port ISA Serial Adapter

SKU CH-VMK1-7Y4EE

Four-port ISA serial card adds 57.60 Kbps RS-232 connections for terminals, printers and industrial equipment

  • Transfer speed57.6 kbit/s
  • Four serial ports expand legacy connectivity via ISA bus
  • 60 Kbps transfer rate handles multi-user terminal traffic
  • On-board I/O processor reduces host CPU load
  • Full modem control and hardware handshaking ensure reliable links
  • Compact 3.5" x 8.7" card fits standard expansion slots

Digi AccelePort Xe ISA Adapter

The Digi International AccelePort Xe is a 4-port ISA multiport serial adapter built to expand a single expansion slot into four independent RS-232 channels. It targets administrators who need to connect multiple terminals, printers or modems to legacy industrial or point-of-sale systems. On-board I/O processing lowers host CPU load while full modem control and hardware handshaking keep each link stable.

For legacy multi-port RS-232 expansion

This card suits maintainers of older PCs or industrial chassis that still provide ISA slots and require four DB-25 serial connections running at 57.60 Kbps. It is not for builders working with PCI, PCIe or USB-only platforms, nor for applications that demand higher throughput or modern serial interfaces.

ISA host interface and four DB-25 ports

The decisive specification is the ISA host interface paired with four 25-pin DB-25 male RS-232 ports supplied via cable; without an available ISA slot and the correct cabling the adapter cannot be installed or used.

Questions about this item

Does the AccelePort Xe 4-port ISA adapter include the DB-25 cables or must they be purchased separately?

The adapter is supplied with a cable that provides four 25-pin DB-25 male RS-232 ports, so no separate cable purchase is required.

The spec lists a 57.60 Kbps data rate — is that per port or shared across all four ports?

The 57.60 Kbps figure applies to each individual port; every one of the four RS-232 channels can run at that speed simultaneously.

With the board measuring 3.5 by 8.7 inches, will it fit a standard ISA slot in my industrial PC?

The card is a full-size ISA plug-in board (3.5" height × 8.7" width × 0.5" depth) designed to occupy a single ISA expansion slot.
