Page 4: Installation
Highly Liquid UMR2 RevC / V1.0 3.0 Installation UMR2 installation consists of two parts: wiring and setup. Both parts must be completed for correct operation. Please visit the UMR2 support forum for details regarding specific host keyboard models. 3.1 Recommended Installation Procedure 1. -
Page 5: Power Wiring
UMR2 support 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. -
Page 6: Prgm And Mode Switches
A PRGM switch is used during the UMR2 setup procedure and during firmware updates. Wire any momentary or latching switch (not included) as shown. A MODE switch is used to select the UMR2 mode of operation. Wire any latching switch (not included) as shown. -
Page 7: Matrix Polarity Jumper
Configures the built-in resistors connected to all UMR2 Matrix Select and Matrix Data terminals • as either pull-up or pull-down resistors. Controls the logic state (low or high) of signals generated by the UMR2 at the Matrix Data I/O • Terminals. -
Page 8: Switch Matrix Wiring
CAUTION: Incorrect wiring of the UMR2 to the host switch matrix can permanently damage the UMR2 and host keyboard. The UMR2 supports switch matrices with up to 9 select lines and up to 8 data lines. Wire the host switch matrix to the UMR2 as follows: Connect each of the host select lines to one of the UMR2 Matrix Select Input Terminals. -

4. Release (open) the PRGM switch. The green STBY LED will blink continuously. 5. Send a single MIDI note to the UMR2. This note specifies the MIDI channel setting for the UMR2. It also specifies the note number that corresponds to the lowest note on the keyboard. To confirm receipt of the note, the red ACT LED will light for several seconds. -
