Introduction
The PCIDIO 24H/48H/96H series products are general purpose digital I/O cards.
This series includes three cards:
lPCIDIO 24H: 24-CH DIO card
lPCIDIO 48H: 48-CH DIO card
lPCIDIO 96H: 96-CH DIO card
The 48H series products are multi-function digital I/O boards used for
industrial PC with a PCI bus. The cards are plug-and-play,therefore it is
not necessary to set any jumpersfor configuration of I/O address or interrupt
PCIDIO 48H and PCIDIO 96H are 48-channel and 96-channel DIO cards
respectively. PCIDIO 24H is a reduced version of PCIDIO 48H, all the functions
are exactly the same as PCIDIO 48H except there are 24 channels only.
The PCIDIO 48H emulates two industry standard 8255 Programmable
Peripheral Interface (PPI) chips operated under mode zero configuration.
The PCIDIO 96H emulates four PPI chips. These two cards are compatible
not only on hardware connectors but also on software programming.
Every PPI connector offers has 3 ports: PA, PB, and PC. The PC can also be
subdivided into 2 nibble-wide ( 4-bit) ports -PC Upper and PC Low. Each
connector is corresponding to one PPI chip with 24 DIO points.
resources.
