We can in VB read the values from an Universal Temperature Probe Model EI-1022 and send out a square wave with a max frequentie of 30 Hz. This is because we used a software timer. We created also the design for the program. Now we are finnishing all paperwork. The paperwork discribes what we have done, our problems/difficulties, what not is finnished, how our program works, the code discription. Next week we give our presentation about our programs.

We can send a value out the DAC ports from the LabJack module. But wen we use program settings from VB it doesn't work any more. This is because a point or comma give a different result but it does'nt related to American or European discription. But we coult fix te problem by settings in windows this changed it automaticly in VB. Now it's working fine.

Finally we found our problem thanks to labjack support. Now we can trie the programs from DotNet_LJUD.zip file that we downloaded from the LabJack site without errors of connection. The DotNet_LJUD.zip file consist out 4 VB programs. We only use Simple, VBSimple and VBStream because we only could use the info of those 3 files. Simple is a VB program that reads some analog and digital ports from the LabJack module and sends some outputs on an analog and digital port. VBSimple is a VB program that reads info from the LabJack module, Driver version, ip- and mac address, serial number, an analog and digital port and a counter. VBStream is a VB program for stream reads on ports from the labjack module.
Note those VB programs are only for connection over USB. You have to change it to Ethernet if you want to use them to do this. See for this section 4.2.2 OpenLabJack() in the LabJack users guide.

You can reed here the sollution to our problem on the LabJack forum from the LabJack site:

We add also Print Screens on this topic so you can see what we did.
