Troubleshooting
If you encounter issues with your summina UMH-21, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply or faulty power cable. | Ensure the USB power cord is securely connected to the DC IN port and a working power source (5V-12V). Check if the power indicator light is on. |
| USB MIDI device not recognized. | USB cable issue, incompatible USB MIDI device, or power insufficient for the USB device. | Try a different USB cable. Ensure the USB MIDI device is USB2.0/1.1/1.0 compatible. If the USB device requires significant power, ensure your power supply to the Host Box can provide up to 2A. |
| No MIDI data transmission/reception. | Incorrect MIDI cable connection, device not sending/receiving MIDI, or MIDI channel mismatch. | Verify MIDI IN/OUT connections are correct (OUT to IN, IN to OUT). Check the MIDI indicator lights for activity. Ensure the sending/receiving devices are configured to the correct MIDI channels. |
| Intermittent connection. | Loose cable connections, power fluctuations. | Secure all cable connections. Use a stable power source. |
