Baud rate for MD4 Diagnostics over CAN

JackT 11 months ago in IQANdesign updated by Gustav Widén (System support) 11 months ago 1


I have reviewed the forums and have seen some comments from around 2 years ago stating that the diagnostics over CAN for the MD4 units using IQANdesign require 250kbps baud rate. Is that still the case or can we use a bus network at 500 kbps? Thanks.

Yes, with 6.08 (and upcoming 7.00), the diagnostics bus is still 250 kbps. 

A later update will make it possible to select higher speed on the diagnostics bus, for systems with MD4 that will enable 500 kpbs.
