Troubleshooting - Assigning active tags

Help for assigning active tags to animal IDs

How can I speed up the pairing process?

  • If possible, assign active tags in a location which is close to the gateway. This can reduce paring time by up to two seconds per active tag.

  • If using active collars, assemble all collars before starting the pairing session.

  • Wake up all active tags before starting the pairing session. To do this, hold the magnet on the magnet icon until the LED flashes twice.

The mobile phone connection keeps dropping out

  • A reliable internet connection is required in the location where you are assigning tags.

  • If you are using an XRS2i or SRS2i EID Reader to scan tags, it must be within 5 m of the mobile phone.

I can't assign tags on my Android phone - the pairing wizard doesn't start

Check the app settings:

  1. Go to Settings > Apps > Datamars Pro> Permissions.

  2. Ensure that Nearby Devices is set to Allowed.

I get an error message about the EID tags being in the wrong format

Datamars Livestock supports EID tags in one of these formats:

  • Decimal1

  • Decimal2

  • Hex

Check that your EID Reader is supported

Only XRS2i and SRS2i EID stick readers can be used to assign active tags. Other models are not supported.

How should I set up my XRS2i or SRS2i EID Reader?


The Bluetooth Connect Mode and Output settings must be set to default.

  1. Go to Settings / Bluetooth / Advanced.

  2. Set Connect Mode and Output must be set to [Default]

Why can't I connect to my XRS2i or SRS2i EID Reader?

Check that the EID Reader is not connected to another mobile phone or Tru-Test device such as a weigh scale indicator. When you first turn on the EID Reader, the LED lights should be off. If the LED lights are on, break the connection with the other device and try again.

What should I do if I have a duplicate ID?

It is essential that each animal can be uniquely identified. See Troubleshooting - Duplicate IDs and fixing errors
