Section 3. Pin Description
3.1 Introduction
There is one connector resident on the control board, labeled J1. It is the
MON08 connector. The following subsection describes signals on connector
J1.
3.2 16-Pin Connector J1
Signals to and from the MON08 connector are grouped together on 16-pin
(2 x 8-pin) ribbon cable connector J1. Pin assignments for connector J1 are
shown in
Table 3-1 . In a production environment, J1 could be replaced by a
“bed of nails” test fixture to reduce PC board parts costs.
