Updater & Serial Number Check

Web Updater is a browser-based tool for updating Opti Deko firmware and checking product serial numbers.

Open Web Updater

This page explains how to:

• Update the Main Unit
• Update an Expansion Unit
• Check the product serial numbers of the Main Unit and Expansion Unit

Before You Begin

Prepare the following:

• Opti Deko
• A USB cable that supports data transfer
• A browser that supports Web MIDI and SysEx
• To update or check an Expansion Unit, the cable that connects the Main Unit and Expansion Unit
• An internet connection

Before updating, close any MIDI applications, DAWs, or other applications that are using Opti Deko.

IMPORTANT During an update, do not disconnect the USB cable, the cable between the Main Unit and Expansion Unit, or the power supply.

Updating the Main Unit

1. Disconnect the USB cable from the Main Unit to turn it off.
2. While holding the Mode button on the Main Unit, connect the Main Unit to the computer with the USB cable.
3. Confirm that the Main Unit’s Color LED flashes white at approximately one-second intervals. This indicates update mode.
4. Open Web Updater in your browser.
5. Select Search for MIDI.
6. If the browser asks for permission to access MIDI, allow access.
7. If multiple devices appear, select the Opti Deko you want to update, then select Connect.
8. After connecting, confirm that the displayed update target is Main.
9. Select Update.
10. Wait until progress reaches 100% and the update-complete message appears.
11. Disconnect the USB cable once.
12. Reconnect the USB cable without holding the Mode button to start the device normally.

After connection, Web Updater automatically selects the appropriate published firmware. You may be unable to update if the installed firmware is already the latest version or is newer than the published version.

Updating an Expansion Unit

1. Turn off the Main Unit and Expansion Unit.
2. Ensure that the Main Unit and Expansion Unit are connected.
3. While holding the Mode button on the Main Unit, connect the Main Unit to the computer with the USB cable.
4. Confirm that the Main Unit’s Color LED flashes white at approximately one-second intervals.
5. Open Web Updater in your browser and select Search for MIDI.
6. If the browser asks for permission to access MIDI, allow access.
7. If multiple devices appear, select the Opti Deko you want to update, then select Connect.
8. After connecting, confirm that the displayed update target is Expansion.
9. Select Update.
10. Wait until progress reaches 100% and the update-complete message appears.
11. Disconnect the USB cable once.
12. Reconnect the USB cable without holding the Mode button to start the device normally.

While updating an Expansion Unit, do not disconnect either the USB cable or the cable between the Main Unit and Expansion Unit.

Checking Product Serial Numbers

Serial numbers appear when you connect the device to Web Updater in update mode. You do not need to perform an update.

Main Unit Serial Number

1. Follow steps 1–8 under Updating the Main Unit to connect it.
2. Check Product serial number under 1. Device Connection.
3. The value shown for Main Unit is the Main Unit’s product serial number.

Expansion Unit Serial Number

1. Connect the Main Unit and Expansion Unit.
2. Follow steps 3–8 under Updating an Expansion Unit to connect it.
3. Check Product serial number under 1. Device Connection.
4. The value shown for Expansion Unit is the Expansion Unit’s product serial number.

When connected in Expansion update mode, you can check the serial numbers of both the Main Unit and Expansion Unit. When connected in Main update mode, you can check only the Main Unit’s serial number.

If You Cannot Connect

• Confirm that the Main Unit’s Color LED is flashing white at approximately one-second intervals.
• Disconnect the USB cable, then reconnect it while holding the Mode button.
• Use a USB cable that supports data transfer, not a charge-only cable.
• Check that the browser’s MIDI access permission has not been denied.
• Close other MIDI applications and DAWs, then select Search Again or Search for MIDI.
• For an Expansion Unit, check the connection between the Main Unit and Expansion Unit.

If an Update Fails

1. Check the error shown on the screen.
2. Reconnect the USB cable and start the device in update mode while holding the Mode button.
3. Select Search for MIDI or Search Again in Web Updater.
4. Select the device, select Connect, and try the update again.

If the same error appears repeatedly, contact the email address listed under Support and Contact and include the information shown under Support details.
