Receiver Code Maps for VEMCO 69 kHz Receivers

 

VEMCO currently has three (3) active code maps – MAP-115, MAP-114, and MAP-113.  Over the next several years, MAP-115 will be become the global standard code map for all 69 kHz receivers.  During the current transition period the correct code map for your study depends on your geographic location and which receiver model you are using.  Refer to the table below to determine which code map you should be using on your receivers.

IMPORTANT:  Do NOT use MAP-112.  MAP-112 is obsolete for all receiver models and cannot detect all 69 kHz coded tags currently sold by VEMCO.

Update to MAP-114 or MAP-115 according to your region by June 2019. See below for details.

Obsolete – No VEMCO receiver should be on MAP-112

 

MAP-115:  MAP-115 will become the global standard code map for all 69 kHz receivers over the next several years.  Introduced to support new tag types that offer new features and functionality, this map has removed support for older tag types. If you still have active tags that use code space A69-1105 (sensors) or A69-1303 (pingers), please discuss the appropriate code map for your studies with your VEMCO sales representative.

MAP-114:  If you are in North America, South Africa, or Australia, you should continue to use MAP-114 for the above receiver models to support the small number of long life A69-1303 tags that continue to be detected by multiple receiver networks.  As these tags expire, MAP-115 will be phased into these regions.

MAP-113:  The current standard code map for VMTs, VR3-UWM and VR4-Global receivers is MAP-113.  Support for newer maps will be made available in the coming months.  Please contact us to discuss how to update these receivers.

Which maps support the code spaces I am using?
Set your receiver maps according to the information in the table at the top of this page.  Additional information on the code spaces supported by MAP-112 (obsolete) and VEMCO’s current active receiver maps (MAP-113, MAP-114, MAP-115) is listed in table below.

Frequently Asked Questions

 

Why are there so many different code maps?+

  • As we continue to support long-life tags sold on older code spaces, we continue to support MAP-113 so that customers with active older code space tags (A69-1105 and A69-1303) and their collaborators can continue to detect their animals.  As these tags expire, old code maps will be retired and replaced with a new global code map (MAP-115) that allows all receiver networks to detect all active VEMCO tags.

What is a Code Map?+

  • A code map, programmed into your receiver, consists of instructions for decoding a collection of VEMCO tag code spaces. Only those tag code spaces that are included in your receiver’s code map will be detected by your receiver.

What is a Code Space?+

  • A code space describes how information is encoded in a tag transmission; it tells a receiver what message type it should be listening for. You can determine the tag code space by looking at the detections in VUE under the transmitter heading e.g. A69-1601-123 or A69-9001-123. The code space and ID number form a unique transmitter identifier.

What are A69-1105 and A69-1303 tags?+

  • A69-1105 and A69-1303 are some of our original code spaces that contained small numbers of unique IDs. A69-1105 was for sensor tags and A69-1303 for pingers. We have not routinely sold these tags for many years. These older code spaces will be superseded in MAP-115 with newer code spaces that provide more IDs and improved error checking.

Are you selling tags that are only supported on new maps?+

  • 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. All tags sold by VEMCO today are supported on receivers configured with MAP-113, MAP-114, and MAP-115. 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.

Should I update to my map now?+

  • Yes, if you are among the vast majority of VEMCO customers who are not tracking any older tags in the A69-1105 or A69-1303 code spaces then we would advise you to update your receivers to MAP-114 or MAP-115 (depending on your geographic location – see table at the top of this page) at your earliest convenience. Note also that the most up-to-date receiver map for VMTs, VR4 Globals, and VR3-UWMs is MAP-113.  As long as you are on MAP-113 or later, there is no need to make a special trip as your receivers can be updated the next time you offload data in the field and initialize with the latest version of receiver software.

    Researchers in North America, South Africa, and Australia who are tracking older A69-1303 tags or collaborating with other researchers who are tracking A69-1303 tags should update their receivers to MAP-114 rather than MAP-115

    Anyone with active A69-1105 tags will need to keep their receivers on MAP-113. Note that new receivers in the VR2 family (VR2W, VR2Tx, VR2AR, and VR2AR-X) as well as VR4-UWM receivers are shipped with newer maps than MAP-113. Please inform your sales rep if you are tracking A69-1105 tags.

    Please note that under no circumstances should any VEMCO receiver be configured with MAP-112. This receiver map is obsolete and cannot properly detect all 69 kHz coded tags currently sold by VEMCO.

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 responsibility on us to ensure that receivers deployed 10 years from now can continue to decode 10 year tags that are sold today. We use our tag database and code maps to carefully manage long life tags and to continue to support them with each new code map release.
