Tzt316f dual mfd No Scx20 on 1 mfd

[Hemlock_SF]

Hello all just finished installing my new system and everything fired up and worked on 1 mfd. when I added the second mfd everything works except Scx20 on the second monitor. MFD’s are set to 0 and 1, Scx20 is 0. Any ideas what could be going on?

are both of your MFD's on the nmea2000 network?

I experienced this problem also, it was due to both MFD's connected by ethernet but only one connected to NMEA2000. Once i connected both to NMEA2000 everything worked properly.

If you change the instance number of your MFD; you must change them all. TZT systems normally don't require the instance be changed but if you do; they all should. This is because the TZTs use a data master concept for the NMEA 2000 bus and we never have more than one TZT talking on the 2000 bus. They all connect to the bus for redundancy and listening to data but only one is ever talking. Please set all your MFDs to the same instance and hopefully that fixes the concern. Mattology is correct that all MFDs should have NMEA 2000 cable connections to the bus.
