Handler Interface Installation
Introduction
Before using the handler interface, connect the pull-up resistors to enable the output signals
and set the dip switch to select the voltage level for the input signals.

Electrical Characteristics

Output Signals

Each DC output is isolated using open collector output opto-isolators. The output voltage of
each line is enabled by putting pull-up resistors on the main board, and by connecting the
pull-up resistors to an externally applied DC voltage.
The electrical circuits of the DC isolated outputs are divided into two groups to be able to
separate power supplies (refer to Table B-1).
A simpli ed diagram of the output signals is shown in Figure B-1 for comparison signals and
Figure B-2 for control signals.
