l An IEEE 802.3af compliant, and UL or NRTL listed, Power over Ethernet (PoE) power source rated Class 0, 2, 3
or 4 must be used. Any other voltage creates a risk of fire or shock and can damage the components. Applicable
national and local wiring standards and rules must be followed.
l To reduce the risk of damage or malfunction due to over-voltage, line noise, electrostatic discharge (ESD), power
surges, or other irregularities in the power supply, route all cables and wires away from high-voltage power
sources.
l Do not install In-Sight vision systems where they are directly exposed to environmental hazards such as
excessive heat, dust, moisture, humidity, impact, vibration, corrosive substances, flammable substances, or static
electricity.
l Do not expose the image sensor to laser light; image sensors can be damaged by direct, or reflected, laser light.
If your application requires the use of laser light that may strike the image sensor, a lens filter at the
corresponding laser's wavelength is recommended. Contact your local integrator or application engineer for
suggestions.
l The In-Sight vision system does not contain user-serviceable parts. Do not make electrical or mechanical
modifications to In-Sight vision system components. Unauthorized modifications may void your warranty.
l Changes or modifications not expressly approved by the party responsible for regulatory compliance could void
the user’s authority to operate the equipment.
l Service loops should be included with all cable connections.
l Cable shielding can be degraded or cables can be damaged or wear out more quickly if a service loop or bend
radius is tighter than 10X the cable diameter. The bend radius must be at least six inches from the connector.
l Class A Equipment (broadcasting and communication equipment for office work): Seller and user shall be
notified that this equipment is suitable for electromagnetic equipment for office work (Class A) and can be used
outside the home.

 Installation

Connect the Breakout Cable (Optional)

CAUTION: A ferrite is included with the vision system standard components. To reduce emissions, the ferrite must
be attached to the Breakout cable.

Note:
l I/O wiring or adjustments to I/O devices should be performed when the vision system is not receiving power.
l The Ethernet cable should be unplugged or the PoE source powered down before making adjustments to
the connections at the far end of the Breakout cable.
l Unused bare wires can be clipped short or tied back using a tie made of non-conductive material.

1. Verify that the vision system's power supply is unplugged and not receiving power.
2. Attach the ferrite around the Breakout cable, adjacent to the strain relief on the cable.
3. Connect the Breakout cable's M8 connector to the vision system's I/O connector.

13
 Installation

Connect the Ethernet Cable

The vision system's ENET connector provides the Ethernet connection for network communications and supplies power
to the vision system.

1. Verify that the PoE injector or PoE switch is unplugged and not receiving power.
2. Connect one end of the Ethernet cable to the PoE switch or PoE injector.

CAUTION:
l The Ethernet cable must be shielded. Cognex strongly recommends Cat 6 or Cat 7 Ethernet cables
with S/STP shielding.
l The Ethernet cable shield must be grounded at the far end. If using a PoE injector, a ground wire
should be connected from the Ethernet shield at the PoE injector to frame ground or Earth ground,
and a digital voltmeter used to validate the grounding. If using a PoE switch, it should have a metal
case, with the case grounded to frame ground or Earth ground.

3. Connect the other end of the cable to the vision system's ENET connector. If using a compatible horizontal screw-
locking Ethernet cable, use a screw driver to tighten the connector screws until snug, to secure it to the vision
system. Screws must be tight to assure a reliable connection.

4. Restore power to the PoE injector or PoE switch's power supply, and turn it on if necessary.

Acquisition Trigger Input

The vision system features one acquisition trigger input, which is optically isolated. The acquisition trigger input can be
configured to trigger from either an NPN (current sinking) or PNP (current sourcing) device.

Specification Description
Voltage ON: 20 to 28VDC (24VDC nominal)
OFF: 0 to 3VDC (8VDC nominal threshold)
Current ON: 2.0 to 2.9mA
OFF: < 250µA
Resistance: ~10 kOhms
Delay2 72µs maximum latency between leading edge of trigger and start of acquisition. Input pulse should be
minimum of 1 ms wide.

l The Breakout cable can be used to trigger from an NPN photoelectric sensor or PLC output. Connect TRIGGER+
to +24VDC and connect TRIGGER- to the output of the photoelectric sensor. When the output turns ON, it pulls
TRIGGER- down to 0VDC, turning the opto-coupler ON. For more information, refer to Breakout Cable
Specifications on page 19.
l The Breakout cable can also be used to trigger from a PNP photoelectric sensor or PLC output. Connect
TRIGGER+ to the output of the photoelectric sensor and connect TRIGGER- to 0VDC. When the output turns ON,
it pulls TRIGGER+ up to +24VDC, turning the opto-coupler ON. For more information, refer to Breakout Cable
Specifications on page 19.

1 Case temperature can be verified using the EV GetSystemConfig(“Internal.Temperature”) Extended Native Mode command. When issued, it
returns the vision system's internal temperature in degrees Celsius, which will be ±5 degrees above the vision system case temperature. Refer
to the In-Sight® Explorer Help file for more information. Additional cooling measures are required if the case temperature cannot be kept
below 50°C. Examples of such measures include: mounting the vision system to a heat sink using the M3 mounting screws, reducing the
ambient temperature and ensuring there is air flow over the vision system.
2 Maximum latency is based on a 1µs trigger debounce.

16
 Specifications

High-Speed Outputs
The vision system features two built-in, high-speed outputs, which are optically isolated. The high-speed outputs can be
used as either NPN (current sinking) or PNP (current sourcing) lines.

Specification Description
Voltage 28VDC maximum through external load.
Current 100mA maximum sink current.
OFF state leakage current 100µA maximum.
External load resistance 240 Ohms to 10 kOhms.
Each line rated at a maximum 100mA, protected against over-current, short circuit and transients from
switching inductive loads. High current inductive loads require an external protection diode.
Delay1 30µs (maximum due to opto-isolators turning ON).

For NPN lines, the external load should be connected between the output and the positive supply voltage (+24VDC
nominal). HS COMMON should be connected to the negative supply voltage (0VDC). The outputs pull down to less than
3VDC when ON, which causes current to flow through the load. When the outputs are OFF, no current flows through the
load.

For PNP lines, the external load should be connected between the output and the negative supply voltage (0VDC).
When HS COMMON is connected to the positive supply voltage (+24VDC nominal), the outputs pull up to greater than
21VDC when ON, and current flows through the load. When the outputs are OFF, no current flows through the load.

1 Delay when opto-isolators turn OFF depends on the load to which the output is connected. With a 240 Ohm load, the maximum delay will be
35µs.

17
 Specifications

High-Speed Output - NPN Configuration

The Breakout cable can be used to connect to an NPN-compatible PLC input. Connect HS OUT 0 or HS OUT 1 directly to
the PLC input. When enabled, the output pulls the PLC input down to less than 3VDC. For more information, refer to
Breakout Cable Specifications on page 19.

High-Speed Output - PNP Configuration

The Breakout cable can be used to connect to a PNP-compatible PLC input. Connect HS OUT 0 or HS OUT 1 directly to
