LJTick-DAC U3

Hello, 

I have tried to use LJTick-DAC on FIO4 and FIO5 with the LJDAC_single example code and got no result when I tried to change the voltage from both DACA and DACB. 

Can you help me on that? I would greatly appreciate it.

You should be able to double

You should be able to double click the DACA and DACB values on Page_0 to pop up a window to apply a new value. If that is not working, there is most likely a configuration issue with the TDAC. Please ensure all of the U3 terminals where the Tick-DAC is attached (should be the FIO4/FIO5 terminal block for the example) are tightly screwed down. I would also recommend you right click the startup sequence and select "Begin Sequence" to ensure the sequence has been run, then try to apply a new TDAC value again.

Hello, 

Hello, 

Thank you for your respond. 

I was be able to get DACB working but not DACA. 

I also included this code: ePut(ID,LJ_ioPUT_CONFIG,LJ_chTDAC_SCL_PIN_NUM,3,0) in the sequences and still not be able to get any voltage coming out of it.

Your new ePut call is not a

Your new ePut call is not a valid configuration. The TDAC_SCL_PIN_NUM configuration should always be aligned to an even numbered DIO. If your TDAC is setup on the screw terminal block with FIO2/FIO3, you should set the configuration to 2.

Once the SCL configuration is set and working for one channel, you should not need to change any other LabJack configurations to use the other channel.
