3.2.2 Power Wiring

CAUTION: Reverse power polarity or supply voltages greater than 6VDC can destroy the

UMR2.

For correct operation, the UMR2 must be supplied with between 3VDC and 6VDC. Select one of the

following power wiring methods. Details for specific keyboards can be found at the

forum.

Method A (Direct)

If the host keyboard has suitable power rails, these can be connected directly to the UMR2 as shown

below.

Method B (Regulated)

The UMR2 requires additional power regulation circuitry when connecting to certain keyboards. In these

cases, the included zener diode and resistor can be used as a voltage regulator.
