Retrofit from NavNet 3D
Retrofit to TZTL12F/15F
Original – MFD8/12 (NavNet 3D)
In this example, the MFD8/12 units are replaced with TZTL12F/15F. While the TZTL12F/15F can use the same Ethernet
sensors as the MFD8/12/BB, the following changes are necessary to cope with more redundant Ethernet and NMEA2000
network architecure.
(1) PSU-017/012/013 is added for DRS2D/4D/4A/6A/12A/25A. Another Ethernet cable is necessary between the PSU
and hub.
(2) All the TZTL12F/15F units have an NMEA2000 drop cable conneced to the NMEA2000 backbone.
(3) NMEA0183 sensors are input to the TZTL12F/15F via a converter or are replaced with NMEA2000 sensors.
(4) The TZTL12F/15F is NOT compatible with Axis IP cameras. Use analog cameras.
(5) Software of the DRS radar may have to be updated to version 1.16

Retrofit from NavNet vx2
Retrofit to TZTL12F/15F
Original – GD1920C (NavNet vx2)
In this example, the GD1920C units are replaced with TZTL12F/15F.
(1) Radar antenna is changed to DRS series. A PSU-017/012/013 is also necessary.
(2) NMEA network is changed to NMEA2000. NMEA0183 sensors should be input to the TZTL12F/15F via a converter or
be replaced with NMEA2000 sensors.
