  • Page 10: Overview

    4 Overview This document describes the functionality and features of the Iron CoaXPress cameras. Iron CoaXPress cameras are high-speed, high-quality devices for image streaming. Using a standard CoaXPress Frame Grabber, connection and streaming can be achieved in a few easy steps and requires a few configurations. Our cameras provide a vast variety of image processing algorithms and configurations to adjust the stream output.

  • Page 11: Stream Metadata Information

    5 Hardware Reference 5.1 Power over CoaXPress Iron CoaXPress cameras support PoCXP (Power over CoaXPress), but must never be connected to an external power source whilst receiving power through PoCXP. Powering the camera with an external power source and over CoaXPress simultaneously may cause irreversible damage.

Adjust as needed and only then pull the cable out. 5.3 Status LEDs The bi-color LEDs behave according to the definition in section 5.4 of the CoaXPress standard. Color-coded indications along with the exact timing for each indicator are described in the following tables: LED state Indication...

  • Page 13: Gpio Connectivity

    5.4 GPIO Connectivity Iron cameras have external inputs and outputs. Some of them are optically isolated while others operate at TTL/LVTTL levels. For pinout of GPIO connector and functional assignment please refer to specific camera datasheet. The following diagrams show GPIO electrical connections: 5.4.1 Opto-Isolated Inputs Opto-isolated inputs don’t share the same ground with the camera, and the voltage difference between the input and return pins must be positive between 3.3 and 24 volts.

  • Page 14: Opto-Isolated Outputs

    5.4.4 Opto-Isolated Outputs There is no pull-up voltage on either contact of the optoisolated outputs. External pull-up voltage of up to 25 volts is required for operation. The voltage between Out and Return contacts must not exceed 25 volts and the current through the switch must not exceed 50 mA.
