Auxiliary RS232 Interface
The 9-pin female Auxiliary Interface connector inside the CBX is to be used by Factory
and Support personnel only.
INPUTS
There are two optocoupled polarity insensitive inputs available on the camera: Input 1
(Trigger) and Input 2, a generic input:
The Trigger is used to trigger the camera so it will acquire an image.
Input 2 can be used as a signal to a software task to perform an action.
The electrical features of both inputs are:
V
AB
= 30 Vdc max.
I
IN
= 10 mA (camera) + 12 mA (CBX) max.
The active state of these inputs are selected in software. Refer to the Camera Setup tab
and Discrete Input tool sections of the Impact Reference Guide.
An anti-disturbance filter is implemented in software on both inputs so that the default
minimum pulse duration is
0.5 milliseconds. This value can be increased or decreased
through the software parameter Debounce Filter. Refer to the Camera Setup tab section
in the Impact Reference Guide for further details.
These inputs are optocoupled and can be driven by both NPN and PNP type commands.
The connections are indicated in the following diagrams:

NOTE
Do not make any connections to the Aux Interface.
NOTE
Polarity insensitive inputs are full functionality even if pins A and B are
exchanged.

CAUTION
Power from the Vdc/GND spring clamps is available directly to the Input
Device on the +V/-V spring clamps, and does not pass through the Power
Switch (ON/OFF) inside the CBX. Disconnect all power supplies when
working inside the CBX.
