Data Highway Plus (DH+) / Remote I/O (RI/O) Adapter PC ISA BUS Interface Card
The DH+ / RI/O Adapter Card is a ISA based module which allows ISA bus computers or OEM based
applications access to AB's DH+ and RI/O networks. The Interface Card allows exisiting 1770-KF2, and
PLC CH0 Serial DF1 drivers to run at the PC's ISA bus speed. This will allow MMI, HMI, SCADA
equipment, and other computer applications access to any DH+ node including PLC's and SLC's.
All settings are accomplished using an easy to use Windows based Configuration Program over the bus
or by using an external RS-232 connection to another computer.
