Labels and QR codes

Updated 2026-11-10

Print a QR label for every room, rack, device, patch panel, and run so that scanning one later opens its page, and use the phone's camera or an NFC tag to find a record or read a serial number instead of typing it.

Print labels for a property or a rack

1. Open the property (or a rack) and press Labels at the top of its page.
2. Under Print labels for, tick what to print: Property, Rooms, Racks, Devices, Patch panels, Runs.
3. Under Under the name, tick the lines each label carries: Type, Path, Short ID, Serial, IP address, Cable ID, Far end.
4. Choose the Stock you are printing on: a Letter or A4 sheet of die-cut labels, 12, 18, or 24 mm tape, or a 2 × 1 in thermal roll.
5. Press Print.

The count under the controls says how many labels and sheets that is, and warns when a label has no room for every line you ticked. Only the labels print. Tape and a thermal roll print one label to a page, so set the printer's paper to the label size shown. Your stock and line choices are remembered on this device.

Put the room's label by its door. On site, scan the room, then the device, and what you file lands where you are standing.

Print wire flags for runs

On a property's labels page, tick Wire flags (both ends). Each run gets a flag for each end, carrying its cable ID and where the other end lands, printed after the other labels.

Scan a label to open its page

On a phone, press the camera button beside the header search box (Scan a code).

1. Hold the label in the frame. Nothing happens until you choose.
2. When the code is read, press Use, or Scan again.

One of this app's QR labels opens that record's page. Any other code is searched for as text. The button is not shown on wider screens.

Read a label's printed text

Where a label has no QR code — a manufacturer's sticker, a hand-written cable tag — the scan sheet can read its words.

1. Open Scan a code and choose Text in Read with.
2. Choose One line or Several lines under Text on the label.
3. Fit the text inside the box (or drag a new box over it) and press Read.
4. The sheet lists the records the text names. Press Open … on the right one, or Search for it if nothing matched. Read again tries once more.

The reading happens on the phone. With no signal, it matches against the properties you kept offline. See Offline.

Read a serial or MAC with the camera

On the device form, the camera button beside Serial number and MAC address (and beside Cable ID on a run) opens the same sheet.

1. Read the barcode with Code, or the printed text with Text.
2. Check the value shown and press Use to write it into the field.

A MAC address is written as colon-separated pairs. Under the MAC field, the form names the maker its prefix belongs to ("Looks like …") as a hint; it never fills in Make for you.

Write an NFC tag

On a room, rack, device, or run page, press Write NFC tag and hold a tag flat against the back of the phone.

• A blank tag offers Write the tag.
• A tag that holds something else offers Replace it or Keep the tag as it is.
• Once written, Lock the tag… then Lock it for good makes it read-only forever. Leave it writable keeps it changeable. Locking cannot be undone.

Writing tags needs Chrome on Android; iPhones can still read them.

Read an NFC tag

Where the phone supports it, the scan sheet offers Tag in Read with. Press Read a tag, hold the tag to the back of the phone, and press Use to open what The tag holds, or Read another.

When the camera is not available

If the browser cannot scan, or the camera was not allowed, the sheet says so in words and you type the value instead. To allow the camera, change it in the browser's site settings.
