qwerty elektronik ab

We have supplied interface units to the diving vessel designed by Defence Consulting Europe AB. This boat is truly unique in the world. It is used to transport divers and is a kind of “cabriolet u-boat”.

Needless to point out, but you need to be dressed and equipped as a diver to be on board!

The nature of the vessel means that everything need to be not only watertight but designed also to cope with the pressure of the diving depth. This means that all added cabling, all added interface boxes and other gear should be avoided as far as possible.

Almost all communication in the system is handled by a network to reduce cabling and to make the most efficient use possible of all equipment. It is equipped with a number of CN8E units. These are used to collect data from NMEA 0183/IEC 61162-1 and NMEA 2000/IEC 61162-3 sensors (GPS, Speed Log, Sounder etc), SAE J1939 main engine data (250 kb/s CAN bus) and legacy 500 kb/s data from the battery systems used for underwater propulsion.

We have developed special versions of the CN8E software to process CAN bus engine and battery data flow to process this for the various control systems.

Further to this, the vessel also contains a number of D8N units and 5N1 units, some of these also with customer-specific firmware versions to handle specific needs,

More information on the DCE website. While you are visiting the DCE site, it is strongly recommended to have a look at the video shots!

Any users of CN8E: We are currently doing final testing of new firmware version, with options for filtering CAN data, added support for IEC 61162-450 compliance as well as a new SW test utility to aid OEM SW development. Stay tuned for news!

The opto-isolated CAN port of the CN8E is set to 250 kb/s to make it compatible with NMEA2000 and J1939 networks. We have come across a project where it is necessary to digest a 500 kb/s CAN bus as a part of a complex Battery Management System on a very special vessel.

We do not yet have a configurable bit rate for CAN via the set-up, but upon request we can deliver this option.

Due to unexpected delivery volumes during late 2011, we have been short of supply of the 1N4B unit.

We are now well stocked and remaining orders will be delivered.

The D8N is using the NMEA XDR message to transmit the status of its 8 opto-isolated inputs at 1 Hz.

Originally as a result of a customer request, we have added an alternative software version that will also transmit a new message each time there is a status change of any of the inputs in addition to the 1 Hz “background” activity.

These and other special software versions are available to all customers. Please define your requirements and we will find out if we have what you need or any similar solution available.

The website structure for qwerty elektronik ab was restructured and rebuilt during the weekend 27-28 August. As far as we know the structure is built and seems to be working and most of the “payload” is imported.

Some linked pdf documents, like manuals, data sheets and type approval documents still need some work but this is in progress.

Please feel free to require any information you need.

Marketing and logistics activities are now moved to a new location, see under Contact. Please update registers accordingly.

The new location is located along a rural postal service, meaning that we would hesitate to use DHL for shipping, since they do refuse to pick up. They will deliver, though.

All other carriers (DPD, EMS, UPS, TNT etc) are fine.
