    Highly Liquid MD24 Hardware Revision G 4.0 Power Supply To operate, the MD24 must be connected to a battery or other DC power supply. A “wall adapter” supply with appropriate specifications may be used. Power supply requirements: Minimum output voltage: 6VDC ●...
  • Page 5: Midi Wiring

    Use the MIDI IN and MIDI THRU ports as shown in Figure 5.1. The MIDI THRU port sends an unprocessed replica of the signal received at the MIDI IN port. The MIDI OUT port can be used to retrieve the MD24 configuration via MIDI SysEx message. See MD24 Firmware User Manual.

  • Page 8: Program Switches

    User-supplied “program” switches can be attached as shown in Figure 6.1. If supported by firmware, a program switch can activate “learn mode” and other programming features of the MD24. Use normally-open momentary switches. See MD24 Firmware User Manual for additional details.
  • Page 9: Outputs

    LEDs, or can trigger other devices requiring a 5V signal. Figure 8.1 shows a circuit which uses an LED to indicate the state of each MD24 logic mode output. The value for current-limiting resistors will depend on choice of LED (1.0kΩ is typical).
  • Page 10: Servo Wiring

    Exact colors vary by servo brand and model. MD24-to-servo wiring is shown in Figure 8.2. Output #18 is used as an example, but the circuit can be connected to any servo mode output. Repeat as needed for each servo/MD24 output pair.
