TackTick

Special Offer!


Special Offer! 25% off NMEA Wi-Fi Gateway

We're offering 25% off the normal price of the NMEA Wi-Fi Gateway Device for a limited time. We made a number of pre-production devices for final testing when developing the product. We're having a clear out, and offering these at a reduced price, whilst stocks last. They are functionally identical to the production devices, except they may have some components hand soldered instead of by robot, or the connector block may be a slightly different size, or other minor differences - all have been updated to the production level of firmware, and are as new.



Connect your TackTick Instruments
to your Phone, Tablet or Laptop

If you have TackTick instruments on your boat, here's how to connect them to your phone, tablet or laptop over Wi-Fi, so you can use them with your favourite navigation apps. This applies to both the original TackTick instruments and to Raymarine TackTick instruments.

You need to have a T122 Wireless Interface as part of your TackTick system, as this lets the instruments interface with other systems over NMEA0183. You will also need an NMEA Wi-Fi Gateway to enable the Wi-Fi connection.

Mount the Wi-Fi Gateway where it will give a good Wi-Fi signal to the users, typically around the cockpit or chart table. Then connect to the TackTick Wireless Interface as shown in the diagram and table below.

We have shown a common power supply being used for the Wi-Fi Gateway and the T122, but if they are mounted some distance apart you may prefer to use separate power supplies for each device. Also, the TackTick T122 has two NMEA inputs labelled NMEA1 and NMEA2. These are identical, so if one is already in use (for example by your GPS), just use the other for the Wi-Fi Gateway. What you cannot do is have two instruments sending data into the same input port. The output port can be split out to feed a number of devices - typically 3 or 4, but this varies according to the instruments.

There is no configuration for the T122, and the default settings for the Wi-Fi Gateway will work without needing changing. If your app is sending data back to the instruments (e.g. route or autopilot data) then you will need to configure the app to connect using TCP, but if it is just receiving data then you are free to use either TCP or UDP.

NMEA sentences are sent and received by the TackTick system as in the table below. Sentences are only sent if there is data. Also, if the TackTick system goes into power saving mode, it stops processing NMEA data.

Some TackTick displays (e.g. T110, T210 Maxi and T215 Maxi) have the ability to have custom data displayed using the PTAK proprietary NMEA sentence. The format of the PTAK sentence seems to have been removed from the web, but some software such as Expedition supports this functionality. Also, some documentation suggests that these additional NMEA sentences are supported: AAM, BWC, BWR, VTG, XTE, ZDA and ZDG. My guess is that since Raymarine bought TackTick these features have either been removed, or at least are no longer documented, to keep the range as a basic, entry level system that doesn't detract from their higher end products.
