# Electrical installation

## GigE interface

The 10 GigE connectors permit to use (direct attach) copper cables with lengths of up to 30 m (10BASE-T). A cable with the minimum specification of CAT6a must be used.

### Network adapter

To establish a 10 GigE connection a network adapter with a 10 GigE RJ45 input must be installed and configured on the PC. The installation of the network adapter is explained in the GCT documentation. For more information, see [Installation GigE](/v1/docs/installation-gige).

For more information about the tested network adapters and the transceivers, see [Tested Network adapters and Transceivers.](/v1/docs/tested-network-adapters-and-transceivers)

| **Electric shock due to improper connection to a power supply.** |
| Use a 12 V – 24 V DC power supply. When using the digital I/O port as a power supply ensure the correct polarity. |

1. Connect the video output port.
2. Connect the digital I/O port.

#### Option 1: Power over Ethernet (PoE)

1. Plug the Ethernet cable into the Power/PoE port (PoEOUT) of the PoE injector and into the video output port (RJ45) of your camera.

2. Connect another Ethernet cable to the Ethernet/data (DataIN) port of the injector and your network card.

#### Option 2: Power supply of the digital I/O port

To set up the wiring refer to section [Digital I/O port](https://docs.chromasens.de/docs/neo-electrical-installation#digital-io-port).

Note the permitted input voltages:

|  | Nominal | Minimum | Maximum |
| --- | --- | --- | --- |
| Permitted voltages | 24 V | 12 V | 28 V |

## CXP interface

The interface allows you to connect two CXP cables. Micro BNC (for CXP12) connectors for the camera and suitable connectors for the frame grabber are required. The maximum cable length is 35 m.

### Frame grabber

To establish a CXP connection a frame grabber must be installed and configured on the PC. Refer to the manual of your frame grabber.

For more information about the tested frame grabbers, see [Tested frame grabbers](/v1/docs/tested-frame-grabbers-1).

1. Connect the video output port.
2. Connect the digital I/O port.

#### Option 1: Power over CoaXPress (PoC)

To use the power-over-CXP function two connections are needed.

#### Option 2: Power supply of the digital I/O port

To set up the wiring refer to section [Digital I/O port](https://docs.chromasens.de/docs/neo-electrical-installation#digital-io-port).

Note the permitted input voltages:

|  | Nominal | Minimum | Maximum |
| --- | --- | --- | --- |
| Permitted voltages | 24 V | 12 V | 28 V |

## Digital I/O port

The following connector is required for the digital I/O port:

- 15 pin HD D-Sub (female)

![neo-digital%20io%20port-v03](https://cdn.document360.io/eca58697-9c2f-461e-9f0a-e6205b74b693/Images/Documentation/neo-digital%20io%20port-v03.svg)Pin allocation D-Sub connector (male) of the camera

You can configure the digital I/O port as RS422 or as single-ended input or output. It is also possible to configure one output as RS422 and the other output as single-ended.
