Test results and examples
• J1939 with 100% busload yields max 2000 msg/sec.• Kvaser BlackBird manages 20 000 msg/sec. 10 times
more than neccesary for such an application.

Some questions
• Is there a need to tie a BlackBird to a computer with passwords?
• Is there a need to have a BlackBird free floating and finders keepers?
• What should happen if a blackbird goes ”out of range”?• What should happen if someone has taken control over a
Blackbird and then gone for the day/called in sick. How to release the BlackBird unit again?

Rugged mechanical data
• A ruggedized aluminium shell with shock absorbent ends made of PUR-rubber.
• A hard shell, but soft enough not to destroy paint job on cars etc. • Very sealed housing. No oil, water, dust etc. IP67. 1 m under water.• One CAN cable going out and One USB with a pocket so that it will
not be in the way or get hooked.• Cables in PUR, takes very low temperatures and high tension loads.• Embedded antenna. Operational within –30C -- +85C. Very few
manages this low temperature.• Self healing label.
1515Thomas Schönbeck, KvaserJune Date, 2008 15
Design, field operative
• Small, approx 15*30*170 mm. Looks more lik a part of cable than a device itself.
• Very easy bring with you on the filed du to size.• In the laboratory, hang it on the wall like any cable.• Pure userinterface, and it’s nice to look at!
1616Thomas Schönbeck, KvaserJune Date, 2008 16
Future features
• Next generation can execute user defined script code.• Next generation can do logging, same function as Kvaser
Memorator.• Embedded SD-memory, handles up to 8 GB (32 GB).• Extra S-RAM memory, for running user code. Memory size
