Power Jack

The power jack of the EM120/EM200EV accepts "large" power connectors with a 5.5mm diameter. Use the APR-1014, APR-1015A, or APR-1018A power adapter supplied by Tibbo or a similar adapter with a 12V nominal output voltage. The adapter current rating should be at least 500mA. On the power jack, the ground is "on the outside," as shown on the figure below.
