Actisense NMEA2000 to Wi-Fi Gateway W2K-2 for Marine Data Transmission and Logging

NMEA2000 to WiFi Gateway

The W2K-2 is a rugged and reliable NMEA 2000 to Wi-Fi Gateway with built-in data logger and Actisense-i diagnostic tools.

Transfer data from an NMEA 2000 backbone to any device (e.g, laptop, tablet, or smartphone) connected to the W2K-2 via Wi-Fi and additionally convert this data to NMEA 0183 using Actisenses renowned conversion engine. Actisense-i is a suite of diagnostic tools and a health checker for your network.

Fully compatible with the industrys most popular apps.

The W2K-2 has built-in conversion of NMEA 2000 messages into NMEA 0183 sentences, thus allowing a wide variety of vessel data (e.g., position, speed, course, wind speed, depth, engine data, AIS messages, etc.) to be shared with NMEA 0183 compatible software applications running on connected devices.

All the data received (or a selected subset) can be logged to an internal micro SD card for later downloading to use for analyzing the voyage. This is very useful for analyzing race data, generating logbooks, diagnosing problems, or even sharing your voyage details. Data can be stored on any micro SD card (up to 128GB), giving weeks or more of storage for all onboard NMEA data.

The W2K-2 has adopted the latest WPA3 standards for password protection. Whilst most wireless gateways still use WPA2, WPA3 adds an extra layer of security.

Actisense-i comes included as standard. Benefit from our full suite of diagnostic tools to help check and diagnose potential issues on a boats electronics network, including voltage issues, and the working status of all devices attached to the network. Actisense-i has been designed to save installers and boaters time and ultimately, money, by giving them confidence in their electronics onboard.

The W2K-2 has the legendary Actisense Reliability Built-In along with useful diagnostic LEDs, an internal antenna, enhanced password security, full certification, and all packaged in an extremely rugged IP67 case.
