Sinking Configuration:
When wiring an isolated input in a sinking configuration to a sourcing output, follow the steps below:

1. Connect the sourcing output of the device to IN.
2. Connect the ground signal of the device to CIN.
3. Connect the common ground between the device and the Power and I/O Accessory to C.

Note: Connecting CIN to a ground signal in a sinking output configuration will result in a short circuit.

Sourcing Configuration:
When wiring an isolated input in a sourcing configuration to a sinking output, follow the steps below:

1. Connect the sinking output of the device to IN.
2. Connect the power supply to 24V OUT.
3. Connect the common ground between the device and the Power and I/O Accessory to C.

Wiring Isolated Outputs:
Some configurations require a pull-up or current-limiting resistor on each output. When using resistors, refer to the following guidelines.

• ISC-178x Getting Started Guide

Installing the Power and I/O Accessory

Complete the following steps to install the Power and I/O Accessory:

1. Connect the included cable to the Camera connector on the Power and I/O Accessory and the Digital I/O and Power connector on the ISC-178x Smart Camera.
   Caution Never touch the exposed pins of connectors.

2. Connect signal wires to the spring terminals on the Power and I/O Accessory:

3. Strip 1/4 in. of insulation from the signal wire.

4. Depress the lever of the spring terminal.

5. Insert the wire into the terminal.
   Refer to the spring terminal labels and the Signal Descriptions section for a description of each signal.
   Caution Do not connect input voltages greater than 24 VDC to the Power and I/O Accessory. Input voltages greater than 24 VDC can damage the accessory, all devices connected to it, and the smart camera. National Instruments is not liable for damage or injury resulting from such misuse.

6. Connect the power supply to the 24 V IN connector on the Power and I/O Accessory.

7. Connect the power supply to a power source.

Wiring the Power and I/O Accessory

ISC-178x Isolation and Polarity
The Power and I/O Accessory has three different grounds for the spring terminals labeled C, CIN, and COUT. The spring terminals with the same label are connected internally, but C, CIN, and COUT are not connected to each other. Users can wire different grounds together in order to share a power supply between the smart camera and the inputs or outputs.

Note To achieve functional isolation, users must maintain isolation when wiring the accessory.

Some wiring configurations may cause the polarity to appear inverted at the receiver. Users can invert the signal in the smart camera software to provide the intended polarity.

Wiring Isolated Inputs
The following images show how to wire the isolated input spring terminals of the Power and I/O Accessory.

Note Isolated inputs have a built-in current limit on the smart camera. It is not usually necessary to use a current-limiting resistor on input connections. Refer to the documentation of the connected device to ensure that the maximum input current limit of the smart camera does not exceed the current capability of the connected output.

Figure 2. Wiring Isolated Input (Sinking Configuration) to Sourcing Output

Caution Connecting CIN to a ground signal in a sinking output configuration will result in a short circuit.

Figure 3. Wiring Isolated Input (Sinking Configuration) to Sinking Output

Wiring Isolated Outputs

Some configurations require a pull-up or current-limiting resistor on each output. When using resistors, refer to the following guidelines.

Caution Failure to follow these guidelines may result in damage to the smart camera, connected devices, or resistors.

• Do not exceed current sink capability of the isolated outputs of the smart camera.
• Do not exceed the current source or sink capability of the connected devices.
• Do not exceed the power specification of the resistors.

Note For most applications, NI recommends a 2 kΩ 0.5 W pull-up resistor. Refer to the documentation of the connected input device to ensure this resistor value is suitable for that device.
Note Resistors with a rating less than 2 kΩ can be used for faster rise times. Users must take care not to exceed the current sink limit of the smart camera or the connected device.

The following images show how to wire the isolated output spring terminals of the Power and I/O Accessory.

Figure 4. Wiring Isolated Output to Sinking Input

Figure 5. Wiring Isolated Output to Sourcing Input

Note A resistor may not be necessary for every sourcing input device. Refer to the documentation for the connected sourcing input device to verify resistor requirements.

Wiring the Lighting Controller

The following images show how to wire a lighting controller to the Power and I/O Accessory. The TRIG terminal connects only to the V terminal through a built-in 2 kΩ pull-up resistor. To use the TRIG terminal, users must wire the terminal to the output signal generating the trigger. Any isolated output may be used as the trigger signal.

Note Review the power requirements for the lighting controller to ensure that the power supply is sufficient to power both the smart camera and the lighting controller.

Forcing the Real-Time ISC-178x into Safe Mode

Users can wire the Power and I/O Accessory to force the ISC-178x to boot into safe mode. Safe mode launches only the services necessary for updating the smart camera configuration and installing software.

Note Users can only force Real-Time smart cameras to boot into safe mode. Windows smart cameras do not support safe mode.

1. Power down the Power and I/O Accessory.

2. Wire the accessory as shown in the following figure.
   Figure 8. Wiring to Force Safe Mode

3. Power on the accessory to boot the ISC-178x into safe mode.

Exiting Safe Mode
