I'm having trouble getting my MC43 to adjust date/time via the TDA message.

I am attempting to send the message through PCAN and I am simulating my display which has SA 18h.

The message I am sending is highlighted below 18D52718h

Time: 16:38:10

Date: 2019 May 21

TDA is enabled in the MC43 program and I am on CAN C.  Does it have to be on the diagnostic CAN bus in order to work?

I want to control COUT from 0-1500mA in MC41 with single directional in three states. 

How can I set parameters of COUT ?

Is there a way to set the DLC of a j1939 frame out?

It would be really useful to be able to search on Qcode comments. For example, if a developer tagged changes with  some sort of date code comment such as "ChangeLog_032_20190527", then it would be nice to be able to search this.

IQANdesign 5.04.14 is now available on check for updates. 

This version solves an issue where a camera image could occasionally fail to show after system startup, it could occur on MD4 systems with multiple SV cameras. See release notes:

We have a machine here with 3 MC43's and an MD4 - the program seems to load in all the modules fine but on startup MC43-1 is showing offline (like it's started in safe mode maybe?).  We checked the address (ID) tag and it seems to have the correct resistance but when we measure Add_L_voltage - it is reading 3.58 V which seems to be above the 3 V that would put it into safe mode and we get the system mismatch error (3 red flashes followed by 3 yellow.  We have tried 3 modules with the same result (the program was loaded in by Ethernet and by canbus with the same results).

Any ideas as to where/what to check that would cause this voltage to be reading high (assuming that is the problem)?

FYI - when I pull the program from the system (Get Project) the MC43-1 program gets pulled along with the others which makes me think it is in safe mode.

From the manual:

"Safe mode
This is a special start-up mode that is used for master modules and puts the unit in a
safe state without starting any application. You may bypass loading the application in
the MC4x on start up (enter safe mode) in two ways.
1 If the ADDR_L voltage > 3.00V (ADDR_L pin shorted to ADDR_H) is detected
when the module starts (during power up) the application will not be loaded. When safe
mode is desired, a jumper is put across pins 4 and 20 on the C1 connector, in place of
an ID-Tag.
2 The MC4x will also start in safe mode if the ID-Tag is absent. This is an easier
method since you can just remove 1 wire of the ID-Tag "

Hi,

Its been years since I have done a MD4 programme and having a memory loss lol.

How do I control which page I want to display on the MD4??

We are attempting to input high precision GPS coordinates through signed 4 byte GPINs.  It appears to only be accurate to 7 significant figures.  Are there any methods to input a int32 with more significant figures?

One of our IQANs is doing math with GPS coordinates, and broadcasts the resulting latitude/longitude over J939-CAN. However, we can't pack it properly. Most likely due overflowing a Float or Signed Int32 value.

According to the J1939 guidelines (, Longitude/Latitude are ought to have a scale of 0,000 000 1 (thus 7 decimals), and an offset of 210. This results in huge numbers. They fit in a UINT32 type, but I suspect IQAN juggling them between either float or signed ints, losing a few bits. Smaller inout numbers like  5,1234567 would work, but higher numbers get trashed.

We could reduce the scale to 6 decimals, but in our case we need the very last centimeters for a precission system, so that's not really an option. Plus we'd like to stay close to the J1939 standard. Other suggestions?
