1 Introduction
The In-Sight™ Strobe Light Adapter (Cognex P/N CLA-2000-00) is designed for use
with an In-Sight 2000 or 3000 system and most Cognex Light Modules (CLMs),
including the Ring Light (P/N CLM-4236), the Dome Light (P/N CLM-7248), and the
Spot Light (CLM-2420). This system can illuminate a part, image it at high speed, and
acquire the “frozen” image.
The Strobe Light Adapter (Figure 1-1) includes an integrated power cable and a Strobe
Control Cable.

Light Adapter in the following sections:

2 Installation
This section describes how to connect the Strobe Light Adapter to the In-Sight 2000 or
3000 processor and the Cognex Light Module.
STEP 1 – Connect the Cables
1. Remove power from the In-Sight processor.
2. Plug the 8-pin male mini-DIN connector of the Strobe Adapter power cable into the
port labeled LIGHTS on the In-Sight processor (Figure 2-1).
Figure 2-1: Connecting to the LIGHTS Port
3. Locate the end of the Strobe Control Cable, which terminates in both the 2-pin
connector and the ground wire loop. Plug the 2-pin connector into the TRIGGER IN
receptacle on the Strobe Light Adapter (Figure 2-2).
Figure 2-2: Connecting TRIGGER IN and Ground

4. Attach the ground wire on the Strobe Control Cable to the threaded standoff on the
front of the Strobe Light Adapter using the supplied screw (Figure 2-3).
5. Locate the end of the Strobe Control Cable that terminates with exposed black and
white wires.
NOTE A two-pin terminal plug may already be attached to the Strobe Control cable. To use the trigger
input on the In-Sight camera you must remove this terminal plug and follow the remaining
instructions in this step. To use the camera without the built-in triggering input, leave the two-pin
plug attached to the Strobe Control cable, then insert the plug into pins 3 and 4 of the receptacle
on the back of the camera.
Insert the white wire into Pin 3 (Strobe +) of the terminal block plugged into the back of
the In-Sight camera. Using a small flat head screwdriver, secure the connection of the
white wire in the terminal block. Insert the black wire into Pin 4 (Strobe –) of the
terminal block on the In-Sight camera, using a screwdriver to secure the connection.
Refer to Installing the In-Sight 2000 or Installing the In-Sight 3000 for more detailed
information on the Strobe Output line on the In-Sight camera.

6. Push the 7-pin DIN male connector from the Cognex Light Module onto either of
the two available 7-pin DIN light module jacks. Rotate the collar on the connector to
lock it in place.
Figure 2-4: Connecting to the Light Module
NOTE The Strobe Light Adapter features two 7-pin DIN output jacks for simultaneously controlling two
Spot Light Modules (CLM-2420). For all other standard Cognex Light modules, the Strobe Light
Adapter can use only a single light.
7. Restore power to the In-Sight processor.

STEP 2 – Adjust the Light Pulse Width
The light pulse width is the duration of time the LEDs will be on during each image
acquisition. The Strobe Light Adapter has two controls for adjusting the light pulse
width (Figure 2-5). The first control is a three-position slider switch labeled X10 that
selects a 0 (0), 100 microsecond (1), or 200-microsecond (2) pulse width. The second
control is a rotary switch labeled X100, featuring positions 0 through 9, which
correspond to pulse widths 0 through 90 microseconds.
Figure 2-5: Light Pulse Width Controls
The light pulse width is set by adjusting both controls until a suitable light intensity level
can be achieved within the In-Sight camera’s exposure time. The effect of the switches
is additive, so any light pulse width between 10 microseconds and 290 microseconds
can be set. For example, if the three-position slider switch is set to 100, and the rotary
switch is dialed to 5, then the light pulse width would be 150 microseconds.
NOTE With both the slider and rotary switch set to 0, the light pulse width is nominally 5 microseconds.
Follow these steps to display the light pulse width while adjusting its duration.
8. Open the System menu. Select Live to enter Live mode.
9. Adjust the X10 and X100 controls on the Strobe Light Adapter to increase the light
pulse width until the strobing operation of the light is visible.

STEP 3 – Configure the Trigger
Triggering the In-Sight camera sends a pulse to the strobe output. The strobe output
generates a 10 mA (minimum) pulse that lasts about two horizontal lines (128
microseconds). During this interval, the camera’s optocoupler switch closes, triggering
the Strobe Controller.
The In-Sight System can be hardware triggered in one of two ways:
• Camera
Connect your trigger circuit to pins 1 (Trigger+) and 2 (Trigger-) on the terminal
block on the back of the In-Sight camera (Figure 2-3). Remember to set the Trigger
parameter within the AcquireImage function’s property sheet (located in cell A0) to
Camera (Figure 2-6). Selecting Camera acquires an image upon receiving a pulse
to the camera input located directly on the camera.
Figure 2-6: Selecting Camera as the Trigger Parameter

• Trigger via the Discrete I/O
Connect your trigger circuit to IN+ and IN- terminals on the In-Sight processor (Discrete
I/O Lines 8 and 9 are on the processor) using the terminal block. Remember to set the
Discrete Input Type to Acquisition Trigger from the Discrete Input dialog (Figure 2-7).
Also, set the Trigger Parameter within the AcquireImage function’s property sheet to
External (Figure 2-8).
Figure 2-7: Discrete Input Dialog

Figure 2-8: Selecting External as the Trigger Parameter
The In-Sight System can be software triggered in one of two ways:
• Manual
Trigger the In-Sight Camera manually by pressing the Trigger button on the Control
Pad or F5 from the keyboard. Remember to set the Trigger Parameter within the
AcquireImage function’s property sheet to Manual.
• Continuous
Set the Trigger Parameter within the AcquireImage function’s property sheet to
Continuous.

3 Troubleshooting
If the light is not strobing, verify the items listed below.
• Verify that all connections are secure.
• Verify the black and white wires on the Strobe Control Cable are securely fastened
within the green terminal plug, and that the plug is firmly inserted into the back of the
camera.
• Verify the Strobe Control Cable is connected to the correct outputs (pins 3 and 4) on
the In-Sight Camera.
• Verify the Cognex Light Module works by itself when connected directly to the
LIGHTS port on the In-Sight processor.
