BNC jack for TTL modulation

SOLIS LED connector

DC input

As the DC20 is a plug & play device, operation is simple:

1. Connect the power supply to the DC input

2. Connect your SOLIS LED to the appropriate connector (4). The DC20 reads out the SOLIS

EEPROM and recognizes the maximum LED current. This value is set as the current limit when

turning the adjustment knob to the right stop. The status LED changes to orange.

3. Push the red knob to switch on the LED. The status LED changes to green.

4. Turn the rotary knob clockwise to increase the LED current.

Notes

You can connect either the SOLIS LED or the power super supply first; the sequence does

not matter.

If you disconnect the SOLIS during operation, the DC20 goes to stand-by.

Each time a SOLIS is connected, the EEPROM is read-out and the appropriate current limit

of the DC20 is set. This way, the LED cannot be damaged.

Please note that the current will change slowly or remain constant over the area where the

rotary knob is close to the left or right stop position. This is normal behavior for the

potentiometer used in the DC20.

(5). The status LED lights up in red.
