4. Adapter AD-SIO4
4.1 Product Overview
The AD-SIO4 is a special adapter designed to provide front panel connection to the PB-
SIO4A using 15-pin Dsub connectors as opposed to the 50-pin connector provided by
the carrier board.
This adapter consists of a separate, 8 HP front panel with four, 15-pin female Dsub con-
nectors mounted on the front side for external device connection, and two, 24-pin, male
dual row connectors for internal connection to the PB-SIO4A carrier board. Connection
from the carrier board to the adapter is done via a 50-way, flat band cable with a 50-pin
dual row female connector for the carrier board, and two, 24-pin dual row female con-
nectors for connection to the adapter. This cable allows for the connection of two PB-
SIO4A’s to two AD-SIO4’s where pins 25 and 26 are not used. See Table 3-4 for the
pinout of this cable.
