The minimum interface to a Photon was power going into the camera, and NTSC (or PAL) video coming out of the camera. An optional accessory called a ‘Power/Video’ cable was sort of a hybrid of the Interface Cable and the I/O Module, except the only connectors at the I/O end were for power (in) and video (out). The power input jack was intended for a power supply such as the one offered by FLIR as part of the Photon Accessory Kit (Universal Power Supply with 6-foot cord). The input power jack mated to the Switchcraft S760 Miniature Power Plug. Pin definitions for the power interface connector on the power/video cable:
Both the I/O Module and Power/Video cable were designed for use with legacy Photon 320 cameras that had the wearsaver connector and wearsaver cover accessories installed, or legacy Photon 640 cameras with the EMI cover accessory.
