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.

Table 3-1. MON08 Pin Assignments
