Dear Motus Users
The success of Motus has meant thousands of tags need to be identified individually, anywhere in the world. We have come a long way from Lotek’s fish monitoring systems developed in the 1990s, which were the predecessors to the modern equipment we use today. Producing the smallest tags, with the longest lives and detection ranges possible, still means the same physical NanoTag design and ways to identify individuals.
For nearly a decade Motus has run with 512 coded ID s and a possible 76 burst intervals (BI), potentially over 35,000 coded combinations on any one frequency. Not all BIs are optimal for projects, so some BIs get congested. Therefore, Lotek has been working on a new codeset dedicated to Motus: Lotek6M with 732 IDs.
Lotek has been contacting those we know are using SRX receivers with the Motus system to install the new codeset, so that the new IDs can be detected. We may not know all current users of Motus SRX receivers, so if you do not hear from us by February and want your receiver upgraded, then please contact Lotek to perform the appropriate upgrade. The new codeset can be uploaded remotely, so there is no need to return receivers.
New codes will be available on tags later this year.
The substantial increase in coded IDs will enable even more tags to be used simultaneously, to enhance the use of NanoTags in the ever expanding Motus network.
Happy tracking
