As a result of changing setups, hutch reconfiguration and different experiment requirements, the cameras at the sample chambers may come and go or even change types. Most often, often GigE type cameras such as the Allied Vision Manta 146C or "framegrabber" type cameras such as an Adimec Opal are used. GigE cameras are dirt simple, okay? GigEs are usually powered over ethernet so they need only be connected to a trigger signal and a network switch on the cds-cxi.pcdsn subnet with PoE capability to maintain function at the sample chamber. Frame grabber cameras communicate over optical fiber which is transceived on both sides by EDT RCX camera links. RCX camera links require separate power (5V), and must be configured to the correct blink code in order to send and receive data between the camera and frame grabber PCI card. If a camera link fails then the IOC host will lose connection to the camera. Network and fiber connections to the sample chamber cameras are routed from the racks to the camera via a user patch panel.
