VME Bridge Controller Features
The GE IS200BCAAH1A IS200BCAAH1ABA connects two independent VME backplane segments intelligently. Specifically, the bridge controller manages data routing between up to 21 slots per segment. In addition, the 32-bit data path transfers information at 40 megabytes per second. Moreover, the bridge operates automatically or allows software configuration for special cases. Furthermore, each segment accesses 16 megabytes of addressable memory space. Consequently, this board enables large Mark VIe systems with many I/O cards.
Dual FPGA and Bridge Architecture
Two FPGA chips provide flexible data routing and protocol management. For instance, the first FPGA handles data from segment A, and the second from segment B. In addition, dedicated bus transceivers drive signals across the bridge without timing errors. Moreover, the access time of 150 nanoseconds adds minimal latency to data transfers. Thus, the bridge appears transparent to software running on either segment.
Energy Storage and Signal Integrity
This printed circuit board stores energy using six onboard capacitors for power filtering. Specifically, two electrolytic capacitors smooth the 5 VDC supply for stable bridge operation. In addition, four tantalum capacitors provide high-frequency noise suppression for the FPGAs. Furthermore, a temperature sensor monitors board ambient for derating purposes. Therefore, the GE IS200BCAAH1A IS200BCAAH1ABA maintains data integrity under heavy bus traffic.
Installation and Diagnostic Indicators
Six LED indicators provide operational status at a glance on this board. First, a green Power LED lights when the backplane supply voltages are present. Second, two green Segment Active LEDs illuminate when each VME segment is operational. Third, a yellow Bridge Busy LED flashes during active data transfer across the bridge. Finally, a red Fault LED indicates bridge configuration errors or hardware failures. Additionally, the board features four mounting holes for secure rack attachment. Thus, you can monitor bridge status instantly without external test equipment.
