This question applies to the legacy Photon camera models. The Photon product line and its accessories have been discontinued. The information here is provided for historical reference.
Connection to a legacy Photon 640 camera can be done using legacy Photon 320 accessories kit if you are using the legacy Photon 320 interface cable (308-0076-00-xx) and a wearsaver connector (250-0194-00) which converts the 30-pin SAMTEC connector to a 15-pin D-sub connector. In this case, the RS-232 communications, analog video output, and input power will operate normally. However, the digital video will not operate.
However, FLIR does NOT recommend connecting a legacy Photon 640 to a legacy Photon 320 I/O module using a legacy Photon 640 interface cable part number 308-0144-0X. The digital video output will not operate, and making such a connection will short one of the camera digital outputs to ground, potentially causing damage to the camera.
The legacy Photon 640 was designed to be used with the ‘universal’ I/O module, part number 333-0018-00. The universal I/O module can be used with either the legacy Photon 640 or the legacy Photon 320, and with either interface cable. Legacy Photon 320 I/O modules and camera interface cables are grey. Legacy Photon 640 I/O modules are blue, and the camera interface cable 26-pin connector ends are blue.
