Cost Savings when Increasing the Number of I/O Lines Industrial users need more and more digital I/O lines to transmit data or to monitor/control outside devices. To meet this trend and to satisfy user's budget considerations, Advantech has developed an extension board for the PCI-1753 called the PCI-1753E. The PCI-1753E has almost the same structure as the PCI-1753, but it has no interface controller. It shares PCI-1753's inter-face controller through a 10-cm flat connecting cable, so users can spend less money to double the number of input/output lines. Accessories The PCI-1753/1753E uses a 100-pin SCSI female connector. For easy signal wiring, a PCI-1753 can be connected to two ADAM-3968 wiring terminals by using a 100-pin to 2x68-pin SCSI cable, part number PCL-10268. The ADAM-3968 allows easy access for wiring the individual pins of a 68-pin SCSI connector. An ADAM-3968/50 wiring terminal converts the 68-pin connector to two opto-22 compatible 50-pin box headers, for connecting the PCI-1753/1753E to daughterboards, such as the PCLD-782B and the PCLD-785B.

The
PCI-1753 is a 96-bit digital I/O card for the PCI bus. It can be
extended to 192 digital I/O channels by connecting it with its extension
board, the PCI-1753E. The card emulates mode 0 of the 8255 PPI chip,
but the buffered circuits offer a higher driving capability than
the 8255. The 96 I/O lines are divided into twelve 8-bit I/O ports:
A0, B0, C0, A1, B1, C1, A2, B2, C2, A3, B3, and C3. Users can configure
each port as input or output via software.
