Can I connect multiple Talkers to an NGW-1?

No, it is not possible to connect multiple Talkers to a NGW-1’s Listener port. (This is in accordance with the NMEA 0183 specification). You can use an NMEA multiplexer like the NDC-5 to combine multiple NMEA 0183 streams together to put into the NGW-1. Alternatively, using more than one NGW-1 is the recommended option.

Note: four NGW-1’s cost approximately the same as one NDC-5 plus one NGW-1.
