VMEbus systems
The past 20 years the VMEbus has reached a dominant position for industrial busses with a number of suppliers.
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.

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.
System description
– five rows – 160 poles
Two additional rows of contacts in the
connector offer new system features:
Additional contacts for I/O and system up-
grade
New voltage supplies for 3.3 V and 48 V
system components
Identifying locations of system components and the bus length. “Plug & Play“
Improved signal/ground ratio for reliable
signal data transfer at rates up to 320 MByte/s

memory cards without closing down the system
User defined pins for test and maintenance bus lines

har-bus 64
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.
Proprietary bus systems can utilise the new contact rows to optimise signal-to-ground ratios and improve system speed.
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.

har-bus 64
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.
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.
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.

inverse
System description inverse
inverse is a 5 row 160 pin connector that supplies additional rows d and z to type R connectors according to DIN 41 612.
Due to the special design of the moulding the male connectors are backwards compatible to 3 row type R female connectors. An internal coding system prevents the mismating of female connectors.
The male connector is fully compatible with all 3 row type R female connectors and the 5 row angled female connector.
The additional contact rows d and z of inverse offer following advantages to the user:
Additional contacts for I/O or new functions
yet to be defined
Improved signal/ground ratio for reliable
data transfer at rates up to 320 MByte/s
Backward compatibility i.e. daughter cards
with 3 row connectors can be upgraded without function loss
Secure mating due to internal coding
Gradual system enhancement on demand
Backward compatible system upgrade with inverse connectors
The inverse types of DIN 41 612 connectors, e.g. 3 row type R connectors, have a strong position in telecoms. However, the trend is for increasing data transfer rates and the demand for additional signal pins.
The 5 row inverse connector system allows a gradual enhancement of existing systems. The 5 row male connector is mateable with both daughter cards with 3 row female connectors and with innovative high-speed boards with 5 row female connectors.
