Config Confusion

[kb3cuf]

Hi- It appears the Iambino will not key the rig (via the FETS) if:

Powered by USB
and
No USB driver installed for the Arduino UNO

After I installed a driver for the Arduino it appeared to work, but I ended up using a generic USB supply and a cable to the USB port on the Arduino.

Is this a known condition or did I find a new "bug"?

What you describe doesn't seem possible. Are you able to reproduce the failure by uninstalling the driver?

You are right, David. It turns out that the USB ports of the HP desktop will not let me key the rig, but powered by my netbook or a 5v USB power supply all is OK. None of the HP USB ports work- the keyer powers on and operates but will not key the radio. Sheesh... it worked briefly last night but is solid not working now.

A keyer and radio with different ground potentials would show this symptom. Put a volt meter between the two grounds and see if it's more than 0V.
