LJTick-DAC doesn't work

I am running the example of the I2C communication to be able to get 10V in the LJTick-DAC in the Labjack T4. I got an error "LabJack Error #2720:  I2C_BUS_BUSY occurred at LJM_eAddresses.vi" which means One or both of the I2C lines are held low. Check the hardware and reset the bus.

I have followed the advice of the error but still, I can't remove it.

Please checkout the T-series and LJM Communication section of the LJTick-DAC page:


You should be able to communicate with I2C, but writing to a TDAC register is much less complicated so I would recommend using that.
