MAP-114 Launch FAQs


Every few years, VEMCO will introduce a new code map which contains new code spaces. New code spaces are required to provide new unique tag IDs, support new tag functionality and provide enhanced data integrity. MAP-114 is being launched to bring in new code spaces to replace an outdated code space, A69-1105 which could only provide 256 unique tag IDs.

We are encouraging customers to update to MAP-114 at their earliest convenience and if possible by the end of 2017. This can be combined with a planned visit to offload data and initialize your receivers.

If you still have some remaining active A69-1105 tags, please contact us at to discuss your options for continuing to detect these tags.

Frequently Asked Questions


What is a Code Map?+

  • A code map, downloaded to the receiver, provides the instructions it needs to detect and decode transmissions from a VEMCO tag. A code map contains a collection of tag code spaces.

What is a Code Space?+

  • A code space is used to describe how information is encoded in a tag transmission. It includes, among other things, the number of pings and the anticipated spacing between those pings. You can determine the tag code space by looking at the detections in VUE under the transmitter heading e.g. A69-1105-123 or A69-9001-123. The code space and ID form a unique transmitter identifier.

What are A69-1105 tags?+

  • A69-1105 is the name of a code space that was used for sensor tags with temperature and/or depth sensors. We have not routinely sold these for several years. They were replaced in 2009 with newer code spaces that provide vastly more IDs and improved error checking.

    Since 2009, we’ve been selling sensor tags on the following code spaces A69-9002, A69-9004, A69-9006. These code spaces are all supported on MAP-114.

What code spaces does MAP-114 support?+

  • MAP-114 supports all current Vemco code spaces as follows:

    • A69-1303

    • A69-1601

    • A69-1602

    • A69-9001

    • A69-9002

    • A69-9004

    • A69-9006

    In addition, this new map supports new code spaces that have not yet been released.

Are you selling tags that are only supported on MAP-114?+

  • No not yet. We introduce a new code map well in advance of selling any of the new code spaces. We know it takes times, often greater than 1 year, for researchers to update all of their receivers as they are often deployed in remote locations. We will be following up with additional communications campaigns before any of the new tags are sold so that we can be sure that everyone has had ample time to update their receivers. We don’t anticipate selling on the new code spaces until late 2018.

Should I update to MAP-114 now?+

  • Yes, unless you or your collaborators are currently tracking A69-1105 tags that have not yet expired. There are very few of these tags still pinging. We have reached out to those we believe are impacted. If you are uncertain, please contact us at The update can be done at your convenience during planned visits to your receiver. There is no need to make a special trip and it is fine to have a mixture of receivers with both MAP-113 and MAP-114. All currently supported VEMCO tags can be detected on both maps.

How do I update my receivers?+

How does VEMCO support long life tags?+

  • Managing code maps, and how tag IDs are assigned on code spaces, is particularly important so that we can sell and support long life (up to 10 year) transmitters. The need for long life transmitters puts an additional burden on the availability of unique tag IDs and requires us to ensure that receivers deployed 10 years from now can continue to decode tags that are sold today. We use our tag database and code maps to carefully manage long life tags and carry support for these long life tags along with each new code map release.
