EASY-ROTOR-CONTROL M V2.2Instructions
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 DCcable 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.

1.5 Insert ICs and the USB-module
The pins of the ICs have to be bend before you can put them into
their sockets. Use a hard base (e.g. your working desk) and
bend the row of pins slightly, that they get an angle of 90°.
Now insert the ICs and take care about direction of the components
and not to bend any pins while inserting the components into the
sockets.
Also insert the USB-module on the socket of IC3 as shown.
1.6 Establishing the USB-connection
Plug the USB-B-connector to the ERC-M and the USB-A-connector to a free USB-connector on your
PC.
Depending on your operating-system, you will be asked to install an USB-driver. This driver is
available on the CD delivered with your kit.
After successful installation of the driver, a new COM-Port (COMn) is available. You can identify the
COM-port-number by inspecting the hardware-settings of your PC. In case you have a conflict with
another COM-port (e.g. virtual COM-port), change the COM-port-number in the properties.

2.2 Assembly of RS232 cable
Materials needed:
- Cable with 3.5mm Stereo phone-jack
- DSUB-connector 9 pole female
- DSUB-case for 9 pole
Pinning of DSUB seen from the connector-frontside
As the delivered cables differ with their colours, it has to be measured which of the inner cables is
connected to what contact of the phone-jack. Alternatively to the 3-wire cable a 2-wire cable with
shielding can be delivered. For this kind of cables the both shielding have to be twisted together. The
shielding is representing GND.
GND: inner contact of the phone-jack : to PIN 5 of the D-SUB
RXD: middle contact of the phone-jack : to PIN 2 of the DSUB
TXD: tip-contact of the phone-jack : to PIN 3 of the DSUB
NOTE: If you use the ERC-M in MASTER-SLAVE-mode over RS232, the pins for RXD and
TXD must be crossed for the Master-ERC-M: TXD to Pin 2 and RXD to Pin3 of the D-SUB.
