Wiring | HDS Gen2 Touch Installation Manual
In smaller NMEA 2000 systems, the power connection may be made
anywhere in the system,
For larger systems introduce power at a central point in the
backbone to ‘balance’ the voltage drop of the network. Use a power
cable without termination.
¼ Note: When joining a NMEA 2000 network with a Simrad SimNet
network, it is important that you do not introduce power to both.
¼
Note:
Do not connect the power cable to the same terminals as the
autopilot computer, pulse radar, bow thruster or other high current
devices - the network may be affected by voltage drop when these
devices are operated. Avoid connection to the engine starting
batteries where possible.
