How to get I2C working on Ardbox (20 IO relay)

Hi,

Has anyone had any luck getting the I2C bus working on the Ardbox Relay HF+?  I have tried multiple I2C devices without any success.

I have been able to successfully program the device and get the other IOs to all wiggle.  The DIP switches are set correctly, but no joy.  I guess I will need to buy and logic analyzer to see if the bus is active at all.

Hi, Did you connect the pull up resistor?
