1.4 PB-SIO4A External Interfacing
Connection of the PB-SIO4A piggyback to external devices is a function of the specific
carrier board for the piggyback. In conjunction with the carrier board there are various
possibilities for connecting the I/O channels of the piggyback to external devices.
For the carrier boards themselves there are three types of connectors available.
Front Panel:
•
50-pin male, double row, flat-ribbon cable connector, locking
•
50-pin female, Dsub connector
On-Board:
•
50-pin male, double row, flat-ribbon cable connector head
In conjunction with the carrier board’s connectors, there is also the possbility of provid-
ing connection to external devices using the AD-SIO4 adapter. This adapter utilizes
either of the carrier board’s flat-ribbon connectors to provide 4, 15-pin female, Dsub con-
nectors. One connector for each channel of the PB-SIO4A. Two PB-SIO4A’s and two of
these adapters can be combined to provide 8 serial I/O channels. The AD-SIO4 is
optional and must be ordered separately. See chapter 4 of this manual for a description
of the AD-SIO4.
