Getting help with Voltrus Tools
Frequently Asked Questions
How does the free trial work?
Click Start free trial in the status bar at the bottom of the window, or choose Voltrus Tools › Unlock Voltrus Tools…. For 14 days every client, simulator and write works with no limits. No account and no payment details are needed. Each Mac gets one trial: starting it again does not restart it.
What happens when the trial ends?
The app becomes read-only. Your saved connections, layouts, points, trends and logs still open, but connecting, simulating and writing to devices stop until you enter a licence key. Nothing is deleted.
How do I buy and enter a licence key?
Open the unlock sheet (status bar or Voltrus Tools › Unlock Voltrus Tools…) and press Buy licence, or buy it in the Voltrus Console. It is a one-time purchase for one Mac, not a subscription. Your key arrives by email and in your console account. Paste it into the Licence key field and press Activate. You can do this during the trial too.
How do I move my licence to another Mac?
On the old Mac, press Remove key in the unlock sheet or in Voltrus Tools › About Voltrus Tools, then activate the key on the new Mac. If the old Mac is gone, enter the key on the new one and choose Move licence here when the app says the key is in use.
Can I try it without hardware?
Yes. Every protocol on the welcome screen has a Demo button: it starts a simulated device on your Mac and opens a client polling it side by side. The same demos are in the command palette (⌘K).
Why does macOS ask about the local network?
Clients connect to devices on your network, and BACnet and EtherNet/IP discovery send broadcasts. Allow Voltrus Tools in System Settings › Privacy & Security › Local Network. If you declined, turn it on there and reconnect.
Why does the app accept incoming connections?
The simulators (Modbus device, MQTT broker, BACnet device, OPC UA server, S7 PLC, EtherNet/IP adapter, DNP3 outstation, NATS server, MTConnect agent, FANUC CNC, SECS/GEM equipment) listen only while you run one, on 127.0.0.1 by default, so only this Mac can reach them. Bind one to another address if a device on your network should reach it.
Why does it ask for Bluetooth?
The Bluetooth LE scanner and GATT client use your Mac's Bluetooth. Allow it in System Settings › Privacy & Security › Bluetooth. Nothing else in the app uses Bluetooth.
My serial adapter doesn't show up.
The serial monitor lists USB, Bluetooth and built-in ports and updates as they come and go. If your adapter is missing, install its driver (some CH340 and PL2303 adapters need one) and plug it in again. A busy port is retried every second, so close any other app holding it.
Does the licence need an internet connection?
Only to activate the key, once per Mac. After that the app checks the key once per launch and keeps working offline: an unreachable server never locks you out.
