System description with switches As a typical multiprocessor bus, VME has to distribute processor information continuously according to the right priorities. This is done through the well known daisy-chain lines. The VME protocol requests 5 daisy-chains on position 1 of every backplane. har-bus 64 These lines are defined to go through every daughter card. Therefore, in case of unloaded card slots the signal have to be bridged across the connector. Bridging variants: 1. The empty card slots may be assembled with dummy cards, that bridge the daisy-chain lines. 2. Bridging can be achieved by inserting 5 jumpers on the back plane manually. 3. Bridging by using IC's with internal integration OR the function may accept automatic daisychaining. daughtercard 02 . 06 4. The new 5-row connector with switches allows an automatic switching. In the case of an unmated daughter card the connector bridges the signals at positions a21-22, b4-5, b6-7, b8-9 and b10-11. The switch elements open automatically when the daughter card is mated, so that the daughter card accepts the ongoing signal daisy-chain. IN OUT male connector female connector OR-gates
5-row connector with switches Integrated switching element har-bus 64 Status: daughter card unmated Advantages: l Passive backplane; no active components assembled l No additional space required, due to integrated switching function inside the connector l No jumpers on the backplane l User friendly regarding maintenance and repairing l Automatically daisy-chaining through mating/unmating the daughter card l High MTBF value l No additional, manual bridging necessary l Less assembly cost, no special tooling required 02 . 07
