Free Up Lattepanda Slot

Skip to comments   Jump to end

Hi, I have a LattePanda integrated into my robot system. On my main PC, it indicates that two slots are being used. How can I free up one slot to allocate it for the robot? Thank you!

First, quick clarification: when you say "two slots are being used," I’m assuming you mean ARC Pro subscription seats (PC activations). If you actually mean the Connection skill’s EZ-B connection slots, tell me and I’ll give those steps instead.

If you mean ARC Pro seats, here’s how to free up a seat on your main PC so the LattePanda can take it.

Steps - release the seat from the main PC

  1. In ARC on the main PC, open the Help tab click Manage Subscription.
  2. Sign in with the account that owns the subscription.
  3. In the subscription portal you will see a list of assigned seats (computer names).
    • Locate the main PC entry that is currently consuming a seat.
  4. Click the Revoke / Release Seat Token button for that computer to free its seat.
    • The seat is immediately released and becomes available to activate on another machine (your LattePanda).

Activate the LattePanda

  1. On the LattePanda, open ARC. When prompted to activate a seat, press Activate.
  2. The LattePanda will consume the freed seat and show in the portal as an assigned computer.

Other options (if you don’t want to revoke)

  • If you want the main PC to keep ARC but not use a seat, you can remove activation on that machine the same way (revoke), then sign into ARC on the main PC with a non-Pro account or run the free version.
  • You can add associated accounts (Account Subscription Add Associated Account) so other users can use subscription seats without sharing credentials: https://synthiam.com/Support/Install/subscription-plans/manage-subscription

If you’re actually referring to EZB Connection slots (the Connection control showing two EZB indexes in use), tell me:

  • whether you want to disconnect one EZ-B (which frees that EZB index), or
  • if you want to use the LattePanda as a headless ARC install while still keeping the main PC connected.

I can walk you step-by-step (with screenshots if you want) - which slot type are you referring to (subscription seat vs. EZB connection index)?
