2xRS232/RS422/RS485 to PCI Bus Card, Full Profile US$75.00

Multi-2P
2xRS232/RS422/RS485 to PCI Bus Card, Full Profile


The Multi-PCI Series of Serial Port PCI Bus Cards are available in configurations that provide 2, 4, 8 or 32 serial ports via a single PC PCI expansion slot and using only one single interrupt. Up to 4 PCI cards per PC are supported, allowing the addition of up to 128 serial interfaces to a single PC. The cards are available with ports that comply to either the RS232, RS422 or RS485 physical interface standards.

The Multi-2-PCI full height PCI Bus Card described on this page adds two RS232 (or RS422/RS485) Serial Interfaces to your PC. This Dual RS232 PCI card supports communication speeds up to 921.6kbps and features configurable slew-rate control for reduced EMI in the RS422/RS485 models. You can select your desired interface standard from the drop down selection box at the bottom of this page.

Dual Serial Port PCI Card Highlights

  • PCI and PCI-X Bus support
  • 2x RS232 or RS422/RS485 serial ports, DB9 male connector
  • Integrated 256 Byte FIFO UART Buffer
  • Speeds up to 921.6kbps
  • 15kV Surge Protector
  • Slew-Rate Control
  • Power supply through communication line (RS232 model, RI signal)
  • Optional 2.5KV optical isolation for RS422/485 (see options below)

Slew-Rate Control

Slew Rate Control can be enabled/disabled via a jumper setting on the Multi-PCI series of cards. Slew Rate Control reduces the data signal's rise and fall times to reduce Electric-Magnetic-Interference (EMI), which is created by steep square wave rise and fall times. However, limiting the slew rate also reduces the maximum data rate from 921.6kbps down to 250kbps.

Optional Opto-Isolation

The RS422/RS485 models are available with optional Optical Isolation to isolate all RS422/485 signals from the PCI bus. The opt-couplers are rated at 2.5kV
