Data Highway Plus (DH+) OR (DH-485) PC PCI EXPRESS BUS Interface Card
The DH+ / DH-485 Card, is a PCI Express based module which allows PCI Express bus computers or
OEM based applications access to AB's DH+ Or DH485 networks. The Interface Card allows existing
1770-KF2, or 1770-KF3 and DF1 Drivers to run at the PC's PCI Express bus speed. This will allow
MMI, HMI, SCADA equipment, and other computer applications access to any DH+ or DH485 node
including PLC's and SLC's.
All settings are accomplished using Dip Switches or an easy to use Windows based Configuration
Program over the bus. More over the card adds to your PC a general purpose RS232 9 Pin DSUB Serial
Com Port.
