Connect an Instrument

You can use Bluetooth or USB to connect your Instrument with your computer. Depending on the Instrument and computer, some connection options may not be available.

Note

Before connecting your MultispeQ to the Desktop App you need to turn on the MultispeQ by pressing and holding the power button for at least 5 seconds.

Current Desktop instrument connection settings

USB connection

1. Select Settings from the left menu bar.
2. Choose the Connection tab from the settings menu.
3. Select the serial port connected to the instrument:
   • Windows: COM followed by a number.
   • macOS: /dev/cu.usbmodem... or another /dev/cu... USB port.
   • Linux: /dev/ttyACM....
4. Select Connect and wait for the app to verify that the MultispeQ responds.

Bluetooth connection

1. Make sure you have your Instrument connected to your computer through your OS preferences. The code for pairing is 1234.
2. Select Settings from the left menu bar.
3. Choose the Connection tab from the dialog.
4. Select the Bluetooth serial port from the connection list:
   • Windows: the COM port assigned to the paired MultispeQ.
   • macOS: the outgoing /dev/cu.multispeq... port, not the incoming /dev/tty... port.
   • Linux: availability depends on the Bluetooth serial profile configured by the operating system.
5. Select Connect. Bluetooth may take a few seconds longer than USB while the app opens the serial port and verifies the MultispeQ response.

Troubleshooting

If you are having trouble connecting to your Instrument, please go through this checklist first:

• Make sure your Instrument is fully charged (at least 6h, or over night).
• Make sure you have turned on the Instrument by pressing and holding the power button for at least 5 seconds. The Instrument will automatically shut off after 3 hours of inactivity by default.
• If you were using the Instrument with another mobile device, you will need to press and hold the power button for 5 seconds to disconnect it from the current device and make it available to the new one.
• If you are using Windows 8 or lower, make sure you have the serial driver (opens new window) installed.
• If a serial port opens but the MultispeQ does not respond, disconnect, confirm that no other phone or computer is connected, and select the outgoing Bluetooth port or the correct USB port.
• A successful connection changes the action to Disconnect. Do not begin QC or a measurement while the app is still verifying the port.
