This Multi-PCI Serial Port PCI Bus Card provides 32 serial ports via a single PC PCI expansion slot and using only a single interrupt. Up to four PCI cards per PC are supported, allowing the addition of up to 128 serial interfaces to a single PC. The card can support the RS232, RS422 and RS485 physical interface standards, which are determined by the connection panels you attach to it.
The product you order from this page is the PCI card only. Included is a cable to connect to the DB9 panels. You must order at least one (and up to four) of the 8-port panels from the options below. You can use any combination of RS232 panels and RS422/RS485 panels.
The picture to the right shows the Multi-32-PCI card with 3x 8-port DB9 Panels attached. A fourth 8-port DB9 panel is shown standing up.
This 32x Serial Communication PCI card supports communication speeds up to 921.6kbps and features configurable slew-rate control for reduced EMI in the RS422/RS485 models. The PCI Card ships with full profile and low profile mounting brackets and a DB44M-DB44F connection cable for connecting the 8-port DB9 breakout panels which are sold separately.
32x Serial Port PCI Card Highlights
- PCI and PCI-X Bus support
- Supports up to 32x RS232 or RS422/RS485 serial ports via optional, expandable 8-port DB9 female break-out boxes
- Integrated 16 Byte FIFO UART Buffer
- Speeds up to 921.6kbps
- 15kV Surge Protector
- Slew-Rate Control
- Power supply through communication line (RS232 model, RI signal)
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 8-port DB9 Panel Serial Interface Options
The Multi-32-PCI Card connects to expandable, female 8-port DB9 Panels via an included DB44M-DB44F cable. The type of DB9 panel you order determines the interface standard: RS232 or RS422/RS485. Up to four 8-port panels can be connected to this card for a total of 32 ports (and can use up to four of these PCI Cards on a single PC for a maximum of 128 ports). You can combine RS232 and RS422/RS485 panels if desired:
Please select the desired DB9 panel option from the options below. Selecting the checkbox in front of the option adds 1 piece to your shopping cart. You can then adjust the quantity in your shopping cart to the desired number of panels and then click on the "Update" button to update the quantities in your shopping cart.
