Despite numerous new bus systems based on the rapid changes in chip technology, VMEbus systems offer significant advantages such as their robustness, reliability and increased availability of processor, memory and I/O cards. Additional advantages appear under real-time conditions, where unforeseen events have to be managed. This is realised with the program interrupt concept and variable control that closely monitors the bus system. With the increase in processing speeds and data transmission rates, 3 row DIN 41 612 connectors have reached their limit, so the VME standard needs to be enhanced further. When VME architecture was increased from 8-bit to 64-bit and data transmission rates up to 160 Mbyte/s (VME 64x), HARTING introduced with 160 pins. This Eurocard connector is 100 % backwards compatible to existing 3 row connectors with 96 contacts, therefore old can plug into new. To offer the best design possible from the start, HARTING developed spice models that were later certified via signal integrity measurements of the connector. 02 . 02 High precision slot structure with VME pinning for connector characterisation. har-bus 64 System description Backward compatibility The design of female connectors allows mating of any combinations of the 5 or 3 row versions without mechanical interference, thus making it possible for users to upgrade and maintain existing systems at lower costs. It is also possible to mate 5 row male connectors with 3 row female connectors. The feature of backward compatibility allows a gradual upgrade of existing Eurocard based systems without the additional cost of a complete system redesign. It is not necessary to replace conventional 96 pin based boards as they remain pluggable into the 160 pin based systems. Not only VMEbus, but also existing proprietary bus systems for which 3 row 96 pin connectors are no longer performance sufficient, provides the opportunity to adapt the system economically without a complete redesign to a new bus architecture. – five rows – 160 poles Two additional rows of contacts in the connector offer new system features: ● Additional contacts for I/O and system up- ● Improved signal/ground ratio for reliable grade signal data transfer at rates up to 320 MByte/s ● New voltage supplies for 3.3 V and 48 V ● Live Insertion for replacing processor or system components memory cards without closing down the system ● Identifying locations of system components ● User defined pins for test and maintenance and the bus length. “Plug & Play“ bus lines 02 . 03 System description The advantages of in detail User-defined pins in the outer rows can be used for application specific functions such as additional I/O. Configured as a shield to provide larger ground return paths, they assure for data transfer rates up to 320 MByte/s. har-bus 64 Proprietary bus systems can utilise the new contact rows to optimise signal-to-ground ratios and improve system speed. 02 . 04 Four preleading contacts (1.5 mm) serve to pre-load the transmit and receive logic so that the bus will not experience glitches during live insertion of new cards into the backplane. Backplane connector terminations are designed in solderless press-in technology. The connector can be installed without any special tooling using economical flat dies for high speed insertion. har-bus 64 The insulator, made of LCP, has an inherent flammability rating of UL 94-V0 and therefore provides an environment friendly connector. In addition, the heat deformation stability of LCP makes the connector surface-mount compatible (see chapter 00). Partially gold plated terminations with precisely formed tips serve as contact area for rear transition boards. system description rear side female connector har·bus® 64 17 mm press-in pins front side male connector har·bus® 64 female connector for crimp contacts 02 05 000 000x daughtercard female connector type C right angled female connector for har·bus® 64 male connector male connector har·bus® 64 male connector har·bus® 64 rear I/O shroud additional daughtercard transition connector right angled female test adapter female connector har·bus® 64 with switches female connector har·bus® 64 daughtercard backplane 02 . 05 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. har-bus 64 The VME protocol requests 5 ­daisy-chains on position 1 of ­every backplane. 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 back­plane manually. 3. Bridging by using IC's with internal integration OR the ­function may accept automatic daisy­chaining. 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. daughtercard male connector female connector IN OUT OR-gates 5-row connector with switches har-bus 64 Integrated switching element 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 Technical characteristics Number of contacts 160 Contact spacing (mm) 2.54 Working current 1 A at 70 °C and all contacts are loaded according to IEC 61076-4-113 Current carrying capacity chart The current carrying capacity is limited by maximum temperature of materials for inserts and contacts including terminals.
