No high current on Blue terminals

[bvduijn]

Hi Jiri,

I was testing my board which I had laying around because I didn't have a suitable power supply at the time. I was at step 3 which says:

3 - If you connect MASTER-OUT pin (digital pin 4 / fifth pin from the top on the left side) to the any of the ground pins, the current on BLUE terminal should increase to a value between 17mA and 23mA. This is a high state of the transceiver line. Outbound thermostat communication is working. Disconnect the pin from the ground.

But I don't get the high value on the Blue terminal. Any ideas ? I think i have a rev 2 or 3 board.

Step 2 is ok and reading ~6 mAmp. I think I might have soldered on the blue led backwards cause that's not working.

TIA
Bert
