Hi guys,

Sorry for my Englisch language, so I am from the Netherlands.

I build the UHU driver ( PCB - Embedded Acquisition Systems), but I don''t know the difference between the program header JP11 (10 pins ) and the header JP13 (3 pins)

With one do I need for using the program UHU-Tuning.exe ? and what's the function of the other header. On the web I can't find the information about this.

I hope there is somebody, who can help me.

With kindly regards from the Netherlands.

Hi,
If this is the PCB you're using, then this must be the schematic for it.

If you look in the center part of the schematic you see the JP13 header which is what you're using to connect it to the PC. On a 9-way serial connector (most common these days) Pin2 is RxD, Pin3 is TxD and Pin5 is GND, just as it says in the schematic. Connect it to J13 accordingly.

JP11 can be used to reprogram the actual UHU-chip, don't connect anything to it.

Hope this clears it up, good luck!

Hi Henrik,

I am very happy with your answer. It's the pcb I used.
Your explanation is clear. Now I can go on with testing the board.

Thanks and greetings from a happy Netherlands.
