What you need.
Compatible device
iPhone or iPad running iOS/iPadOS 17 or later, or a supported Apple silicon Mac.
Ethernet path
A USB-C Ethernet adapter, a compatible powered Lightning adapter chain or the Ethernet port of a Mac.
Local service network
A working Ethernet cable and authorised access to the intended D1 network.
Known credentials
The network range, a free device address and authorised credentials for the selected system.
Configure the network carefully.
Connect the correct adapter path
Connect USB-C devices through an Ethernet adapter. Lightning devices need a compatible powered adapter chain. Link LEDs help confirm the physical connection.
Assign a free IPv4 address
Configure an unused Ethernet address in the same subnet as the target system. Never assign a controller address to the iPhone or iPad.
Allow local network access
Accept the system prompt on first use. The permission can be reviewed in Privacy & Security → Local Network.
Select the correct project
The same IP addresses may exist at different sites. Choose the building deliberately before connecting.
Verify identity before live actions
Compare the IP address, project, device identity and detected version before reading data or sending service commands.
Explore the app safely.
Demo mode
The demo project contains fictional controllers, lines, call stations, events and measurements. Simulated connections never send commands to a network.
Import a VCF
A VCF list can be imported as an offline controller. Its data stays assigned to the project and can later be refreshed from the real installation.
When a connection cannot be established.
The controller is not found by the scan
Check the Ethernet link, local network permission and scan range. A known IP address can also be added manually to the correct project.
“A valid IPv4 address is required” appears
Remove spaces and use four numeric blocks between 0 and 255. The address must match the service subnet and remain unused.
A command returns “NO EXECUTION PERMISSION”
The action requires OPMODE CONFIG. Enable it deliberately on the selected controller and return to OPMODE NORMAL after the work is complete.
The same IP exists in multiple projects
This is common in D1 installations. The selected project and verified device identity are decisive; a detected IP is never assigned automatically to another building.
