Chart Sharing


Rear Connections

1 – NMEA 2000 | data input / output
2 – ETHERNET | High bandwidth data ( radar, sonar chart)
3 – POWER – 12v input & NMEA 0183 | Optional video-in via adapter
4 – SONAR – CHIRP & Broadband Sonar
5 – STRUCTURE – StructureScan HD Sonar


Lowrance HDS-7 Gen3 Touch - Rear Connections


Connecting directly to a single device – The ethernet port is auto sensing, meaning that the unit can connect to one network device directly, without the use of a crossover cable or switch.


Lowrance HDS-7 Gen3 - Single Device Connection


Connecting to multiple devices – If connecting more than one ethernet device to a HDS-7 display, or two devices to a HDS-9 or HDS-12 display, use the optional network expansion Port (NEP-2).

If the number of Ethernet devices exceeds the number of available ports on the NEP-2, it is possible to link two or more NEP-2 modules together to provide the required ports. The NEP-2 modules are fitted with 5 Ethernet ports.


Lowrance HDS-7 Gen3 - Connection to Multiple Devices


NMEA 0183 device connection – The HDS Gen3 display has an NMEA 0183 serial port, providing both an input and an output.

The port uses the NMEA 0183 (serial balanced) standard, and can be confi gured in the software for diff erent baud rates up to 38,400 baud. The NMEA 0183 cable shares the same plug as the power cable.


Lowrance HDS-7 Gen3 - NMEA 0183 Connection


NMEA 2000 device connection – All HDS Gen3 models are equiped with a NMEA 2000 connector, which allows the receiving and sharing of a multitude of data from various sources.
