Can I connect multiple Listeners to an NGW-1?
The NGW-1 talker port can drive up to 20mA. This means that potentially up to 10 NMEA Listeners can be connected to the NGW-1 output. Check the input currents of each Listener to see how many can be connected together.
Note that many NMEA Listeners do not provide isolation on their inputs. Connecting these together can cause ground loops and thus damage to the Listener ports of these devices. For safe connection of multiple Listeners our NBF-3 NMEA Buffer is recommended.
