- ISC-178x Getting Started Guide
Installing the Power and I/O Accessory
Complete the following steps to install the Power and I/O Accessory:
- 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.
Ịkpachara anya, emetụla ntụtụ njikọ ndị ekpughere anya. - Connect signal wires to the spring terminals on the Power and I/O Accessory:

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.
Rịba ama 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.
Rịba ama 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.
Ịkpachara anya 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.
Rịba ama 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.
Rịba ama 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
Rịba ama 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.
Rịba ama 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.
Rịba ama Users can only force Real-Time smart cameras to boot into safe mode. Windows smart cameras do not support safe mode.
- Power down the Power and I/O Accessory.
- Wire the accessory as shown in the following figure.
