How to rename input ports on the CommBox Classic S5

Applies To

CommBox Classic S5 — All models (Goanna firmware and above)

Step-by-Step Instructions

Step 1: Access the Device Settings menu

• Swipe up from the bottom centre of the screen to open the Device Settings swipe-up menu.

Step 2: Go to Lock settings

• Scroll across the tabs at the top of the Device Settings menu and tap Lock.

Step 3: Enable Input Renaming

• Scroll down and toggle on Allow Input Source Renaming.

Step 4: Rename an input

• Tap the input you want to rename from the list.
• A text field will appear — type your custom name, for example:
  • Teacher PC
  • Guest HDMI
  • Apple TV
  • Video Conference
• Tap Save.

Step 5: Confirm the new name

• Open the Launcher or the swipe-up inputs tab.
• Your custom name will now appear in place of the default input name (like HDMI 1 or USB-C).

💡 Tip: In a meeting room or shared classroom with several permanently connected devices, renaming inputs makes a big difference — guests can switch to the right device in one tap without asking for help.

Troubleshooting / What to Do If It Doesn't Work

• Cannot find Allow Input Source Renaming — confirm the screen is running Goanna firmware or later. Update via Settings > System > System Update if needed.
• Custom name is not appearing in the input selector — close and reopen the Device Settings menu, then check the Launcher inputs list. A restart may be needed if the name does not update immediately.
• Input name has reverted to default — this can occur after a firmware update. Re-enable Allow Input Source Renaming and re-enter your custom names.
