Connector: BM12B-GHS-TBT&#x20;

[Mating Connector: GHR-12V-S](https://www.digikey.com/en/products/detail/jst-sales-america-inc/GHR-12V-S/807824)<br>

The camera is able to auto-negotiate the Ethernet speed.  Therefore, only four pins are required for slower 10Base-T or 100Base-T speeds.  All eight pins are required for communication at a 1000Base-T speed.

Typical users will choose either J3 OR J5 depending on their specific installation requirements. Many of the signals are shared between J3 and J5 including the primary input power, UART, and I2C connections.  The following connections are shared between the connectors:

Camera power input (6V to 26V): VCC & GND

J3: pins 1-2&#x20;

J5: pins 11-12&#x20;

3.3V UART bus: RXD & TXD&#x20;

J3: pins 3-4&#x20;

J5: pins 9-10&#x20;

3.3V I2C bus: SCL & SDA&#x20;

J3: pins 6-7

&#x20;J5: pins 5-6

## Display Indicators

The camera contains two indicators for providing feedback on the camera’s operation. The indicator closest to the top of the camera identifies camera Power, while the indicator closest to the bottom of the camera identifies camera Status.  Each display indicator contains a set of LEDs: a green LED and a red LED .

Once the camera is powered, both the green and red LED of the Power indicator will be on.  The status indicator LED uses both green and red LED to indicate the current state of the system, per the following diagrams.
