Installation Guide
One device. Any boat.
Minutes to install.
The Velamari Pulse works on sailboats and motorboats — with or without instruments. Pick the path that matches your boat, and you're done. No technician, no haul-out.
NMEA 2000
Sailboats & motorboats with N2K backbone
What you get: Full sensor data — depth, wind, speed, heading, engine, plus GPS and motion.
Find the NMEA 2000 backbone
Look behind the nav panel or helm station for the round black Micro-C connectors and T-connectors daisy-chaining your instruments.
Plug in the T-connector
Add a T-connector to an open drop on the backbone — any standard NMEA 2000 Micro-C T-connector works (e.g., Lowrance 000-0119-79, ~€15). The Pulse plugs in via its Micro-C cable. One cable = power + data.
Scan the QR code
Open your phone camera, scan the QR on the device label. This claims the device to your fleet and assigns it to a boat. Built-in SIM connects automatically — no WiFi setup. You can also claim a device manually by entering its MAC address.
Mount the device
Stick the Pulse to any flat surface with the included adhesive mount. Behind the nav panel, under the helm, on a bulkhead. The IMU auto-calibrates — no alignment needed.
NMEA 0183
Older instruments, typically 2005–2015 boats
What you get: Full sensor data from your chartplotter or instrument head — same as Path A, just wired differently.
Identify your 0183 output
Find the NMEA 0183 output on your chartplotter or instrument head. Check the brand guide below for your specific tap point.
Connect three wires to the screw terminal
Run three wires from the instrument's 0183 output to the Pulse: RX+ (data), RX- (data return), GND. The screw terminal accepts 0.5–1.5mm² wire — no soldering needed.
Connect power
Wire the included power cable (bare leads) to your 12V switch panel. Red to +12V, black to ground. Inline 3A fuse included.
Scan the QR code
Scan the QR on the device label to claim it to your fleet and assign it to a boat. You can also claim a device manually by entering its MAC address.
Mount the device
Adhesive mount on any flat surface. Done.
Power only
Day boats, motorboats, boats without instruments
What you get: GPS tracking, motion detection, and barometric pressure from the Pulse's own sensors. No instruments needed.
Connect the power cable
Wire the included power cable to your 12V switch panel or battery. Red to +12V, black to ground. That's the only cable.
Scan the QR code
Claim the device to your fleet. The Pulse uses its built-in GPS, IMU, and barometer to track the boat automatically. You can also claim a device manually.
Mount the device
Stick the Pulse anywhere rigid — behind the helm, on a shelf, under the dash. No alignment required.
Which path for your boat?
Common charter fleet brands and the recommended installation path.
| Brand | Path | Notes |
|---|---|---|
| Jeanneau | A | Standard Micro-C backbone. Plug in directly. |
| Bavaria | B | Raymarine SeaTalk. Tap the ST60 instrument head — the chartplotter doesn't retransmit SeaTalk on 0183. |
| Beneteau | A or B | Pre-2015: NMEA 0183 via B&G Triton. 2015+: NMEA 2000. |
| Hanse | A | SimNet/NMEA 2000 backbone. Older models (2005–2012): use Simrad IS15 J4 port in "talk" mode. |
| Dufour | A | B&G instruments, NMEA 2000 backbone on most recent models. |
| Lagoon | B | Raymarine MFD (E120/C120). 0183 output at the chart table in the saloon — easy access. |
| Fountaine Pajot | A | B&G backbone on recent models. Older models: check for NKE Gyropilot 0183 output. |
| Elan | A or B | Common in Adriatic charter. Check connector type behind helm station. |

Note: German boats (Bavaria, Hanse) may reverse NMEA 0183 polarity. The install guide in the box covers this.
NMEA 0183 screw terminal pinout
For Path B installations. The 3-position screw terminal on the Pulse accepts 0.5–1.5mm² wire. No soldering, no crimping — strip, insert, tighten.

What happens next
From plug-in to live data on your dashboard.
Connected
Built-in SIM finds the nearest cell tower. No WiFi, no hotspot, no configuration.
First data
GPS position, motion, and instrument readings appear on your fleet dashboard.
Calibrated
The IMU learns the boat's forward axis from motion patterns. Heel and pitch readings are accurate.
