Description
True Heading CTRX VISION+
5W Class B-SOTDMA AIS transponder with splitter & WiFi*
The new True Heading CTRX Vision+ is a modern 5 Watt AIS class B transponder, which uses the SOTDMA protocol. Just like AIS class A equipment, CTRX Vision+ participates in the time slot reservation plan, so it will always have a free timeslot available to transmit it’s position, at a higher update rate.
Former types of AIS, such as our previous Graphene AIS series, are CSTDMA transponders. These first listen to determine if there is a free time slot that can be used. This works fine at sea, but not in port areas and busy waters such as the English Channel and waterways around Antwerp and Rotterdam. In these areas, certainty about visibility is essential. Older type of transponders that just skips broadcasts because there is no free time slot, do not offer this certainty. True Heading CTRX Vision+ does.
The CTRX Vision+ has a built-in high performance antenna splitter, which shares the antenna with the VHF antenna without signal loss, an option that is very useful for the leisure market where finding a good location for an extra antenna causes problems.
CTRX Vision+ is small and light, ultra power efficient and easy to install.
Of course, the transponder can be connected to the plotter or tablet with the electronic chart in many ways: NMEA 0183, NMEA2000, WiFi and USB.
*WiFi option is available now
