Hello,
I'm using U3(Python 2.7 on Cygwin ) and ran out of DAC port so need to set up extention currently other IO pins on U3 all in use. I have CB15 Terminal Board can I set up extra DAC ports using LJTick DAC via CB15? If yes, where can I have reference?

Yes, you can use the CB15 with an LJTick-DAC. The CB15 provides screw terminals for EIO0-7 and CIO0-3, which are digital I/O lines 8-15 and 16-19.
The LJTick-DAC datasheet can be found here:
https://labjack.com/support/datasheets/accessories/ljtick-dac
We have a Python LJTick-DAC example here:
https://github.com/labjack/LabJackPython/tree/master/Examples
I2C (using the i2c method) is used for communications between the U3 and LJTick-DAC. With the SDAPinNum (DIOB) and SCLPinNum (DIOA) parameters you specify what U3 digital I/O lines the LJTick-DAC is connected to.
I added a new example ljTickDacSimple.py. This is a simpler example in comparison to the LJTicDAC\LJTickDAC.py which is GUI based.
Thank you so much this is just waht I was looking for
