So fare, don’t put the ICs (MEGA328, USB-Module and ULN2003) into their sockets.

First a little electrical test should be performed:

1.4 Connection of the DC-supply and check of the voltage-regulator

Now put the jumper on the 1x2 pinheader JP1 (the jumper supplies the ERC with +5V).

After checking all assembled components for identity, polarization and solder-bridges, prepare a DC-

cable with 10 to 15VDC by using the DC-connector supplied with the kit or use any other DC-supply

with that voltage and an appropriate DC-Connector of 2.1/5.5mm.

Connect the Plus(+)-pole to the center contact

and the Minus(-)-pole to the outer contact.

Before connecting the DC-connector to the

ERC-M, measure the voltage at the connector,

if it is in the range needed.

If DC is reversed, nothing will happen as the

Circuit is proven against wrong polarization.

Now plug the DC-connector into J1 of the ERC-M. After connecting DC correctly, you should

measure +5VDC +/-0.2V at the test-point +5V and +10 to +15VDC at test-point +12V against GND.

Disconnect the supply now.

Testpoint +5V Testpoint +12V
