IDentifiers for Podcatcher Classic

3 min readUpdated Nov 2026

An IDentifier is a small infrared transmitter that you place next to an object, at the entrance of a room or at the start of a tour. A visitor points the Podcatcher Classic at the IDentifier, the device receives its code and plays the content linked to that code. This page explains the types of IDentifier, their codes and batteries.

Podcatcher Classic only responds to infrared. The visitor has to aim the device at the IDentifier.

TypeWhat it does
Object IDentifierThe most common type. Starts the content of one Stop.
Start IDentifierAn Object IDentifier with a flag on its label. Starts a tour in the language of that flag.
AV-Sync IDentifierWired to an AV-Sync box and plays audio in sync with a video. Cannot work on its own.
Warning IDentifierMains-powered transmitter near the exit that makes the Podcatcher Classic sound a warning signal.

Every IDentifier sends its own unique infrared code. The code is printed on the back of the device and has four pairs of characters, for example EF:FE:1C:AE.

  • You can link an Object IDentifier to one Stop per tour, but you can use the same IDentifier in several tours.
  • An IDentifier cannot be an Object IDentifier and a Start IDentifier at the same time.

To use one, note the code on the back, add it to a Stop in the Tour Editor on the Platform and place the IDentifier near that Stop. When a visitor points the Podcatcher Classic at it, the Stop plays.

A Start IDentifier uses the same kind of code as an Object IDentifier, but it starts a tour in a specific language. You can link a Start IDentifier’s code to a site only once — otherwise the Podcatcher Classic would not know which tour, or which language, to start.

An AV-Sync IDentifier sends its code and the current position in the video. It is connected by cable to an AV-Sync box, which does most of the work. See AV-Sync for Podcatcher Classic.

See Warning IDentifier.

There are two generations of the battery-powered IDentifier.

You can keep using your IDentifier V2 units, but we cannot replace them or send out extra ones.

The newest IDentifiers also contain Bluetooth. It was only used by the Guide-ID app, which has been discontinued, and is no longer used.

Under good conditions an IDentifier battery lasts one to two years indoors. Replacing it is simple — see Replacing IDentifier batteries.
