4.10 Data Acquisition I/O Connector – J14 (Model PR-Z32-EA only)
Prometheus model PR-Z32-EA includes a 50-pin header labeled J14 for all data acquisition I/O.
This header is located on the left side of the board. Pin 1 is the lower right pin and is marked on
the board. Diamond Systems’ cable no.
C-50-18
provides a standard 50-pin connector at each
end and mates with this header.
