FASTBUS CRATE
The Bi Ra Model FB 8127 - R3 meets all requirements of FASTBUS specifications and IEEE Standard 960 for Type (A) air-cooled crates. This fully redesigned crate is a standard rack-mountable package with 26 slots. The backplane of the crate consists of two parts: the Segment and the Auxiliary Backplane. The FASTBUS "Segment" is the digital data bus which provides the control and flow of data in the system. The FASTBUS "Auxiliary" is a separate PCB (optional) which is not employed for the transfer of data, instead it is used to implement optional features such as analog outputs to trigger logic, rear-panel inputs or custom I/O. The 26 station Segment Assembly is an eight (8) layer printed circuit board with ground and power planes embedded. The NEW Segment and Auxiliary connectors provide accurate placement of either flat or long half-slotted module connectors and pins are field replaceable.
The Model FB 8127 "A" FASTBUS Crate meets all requirements of the FASTBUS Specification (DOE/ER-0189) of the U.S. NIM Committee. The Crate is a 26 station, air cooled crate with a multilayer segment PCB capable of providing full power to modules. Electroless nickel-plated guide rails insure smooth alignment and minimizes air obstruction for cooling of the modules and provides excellent ground return (especially for analog designed modules). All support and mounting bars have been strengthened and self-locate through side panels.
The Halt/Run Bar actuates a switch mounted in the front mounting bar of the bottom rack. Pressing the center front of the bar allows the bar to release (halt position) and drop down, allowing the insertion or removal of a FASTBUS module. The bar will not lock into place (run position) unless modules are fully inserted into crate. The new design allows user to release bar (halt position) on bench top.
The redesigned busbar and digital return allows the user to attach and disconnect power cables easily. Power connections for the +5V, -5.2V, and -2V are made to tin plated copper bus bars attached to the bottom of the Segment PCB. Digital Return is mounted directly above the power connections on the Segment PCB to a tin plated copper bus bar. New strain relief clamps secure the heavy power and digital return cables. New safety shield covers protect these connections and indicate proper placement of cables. The analog voltages (+/-15V) and returns (split between stations 0-12 and 13-26) are soldered to the Segment PCB and brought to two connectors at the bottom rear of the Crate.
