The DynamicSignals / Kinetic Systems 3922 Series CAMAC Parallel Bus Crate Controllers are a double-width CAMAC crate controller that connects to the associated computer interface card via a parallel bus. When used with the Model 2926, 2927, or 2928 interface card, the combination forms a computer-based CAMAC system with an IBM PC/AT reg. or PS/2 or compatible processor as the host. The Model 2922 interface card can also be used with the 3922 to form a DIGITAL Qbus-based CAMAC system. A Macintosh II host is interfaced using the Model 2932, any VME-based computer is interfaced using the Model 2917, and PCIbus systems can utilize the 2915 PCI adapter.
Up to eight 3922s can be addressed on the interface bus. The crate address (0 through 7) is selected by a front-panel switch. A single 40-wire ribbon cable is connected to the computer interface card and looped through the crate controllers. Interface bus connections are made at the rear of each 3922. The last 3922 terminates the bus. RS-485 balanced-line signaling is used on the interface bus to allow reliable operation with up to 91 meters (300 feet) of total bus length. Twisted-pair, flat-ribbon bus cable enhances data integrity. The eight-bit interface bus is multiplexed for address and data transfer. Appropriate control/response signals are also included.
