APE1553-1/2(-DS) Hardware Manual
2.4 Board to Board Connector (B2B connector)
The Board to Board connector provides the eight General Purpose Discrete I/O signals
(GPIO’s) and an additional “one pin” combined IRIG-B Master-Output/Slave Input on a
16-pin ribbon cable connector (mounted on the upper right corner, see figure the figure
below).

Table 2.4-1: B2B connector Pinout
For connecting multiple APE1553 boards together a 16-pin standard ribbon cable with a
coded ribbon cable connector is used. It’s important to use coded connectors to avoid
damages caused by signal collisions.
