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.
