How to Enter the MMSI Number and Other Details to a Vesper Marine® Transponder

An MMSI number is required before an AIS Transponder can send messages on the AIS network. 

If a Vesper Marine® transponder wasn't preprogrammed by the dealer, it must have a valid MMSI number. The transponder will work in receive-only mode until the MMSI and vessel details are entered.

There are several ways to enter the MMSI into the transponder:

1. Cortex® Hub M1-USA models must be programmed by an authorized Vesper® representative. This can be done remotely (with software version 1.6 or higher) via the Cortex Cloud connection or a Vesper Secure Message (.vsm) file can be sent to the user to send to the Hub using a smart phone

2. Cortex M1 Hub-ROW models can be programmed directly from the Cortex Handset or Cortex Onboard™ app.  Alternatively, a dealer may also do this remotely via the Cortex Cloud

3. All WatchMate® transponders can use the vmAIS PC Configuration Program. Connect to the transponder using USB or WiFi (XB-8000 and Vision only). Download and install the latest version from Garmin Support Center

4. WatchMate 850 and WatchMate Vision® have a configuration screen where your MMSI and other details can be entered. For WatchMate 850, use the Setup menu for "AIS Transponder / Your Vessel Details". For WatchMate Vision, touch the settings icon and then use the wheel menu to select "AIS Settings"

5. For XB-8000 and WatchMate Vision use the WatchMate iPhone app. Install the WatchMate app from Apple Store

Never use an unassigned or false MMSI (this is illegal in most countries). Be certain you enter the MMSI carefully. The MMSI cannot be changed once it has been entered without contacting a dealer or Vesper Marine.
