processed. The DRS may be in either Transmit or Standby modes of operation. If
the DRS is powered from a separate breaker and the DRS is powered OFF while
the MFD are ON, no data will be passed through the DRS CanBUS port.
Q8.CON Does TZtouch use the same Power Supply Units (PSU) as NavNet 3D?
The PSUs for NavNet 3D and TZtouch are the same. However, a modification must
be done inside the PSU when connected to a TZtouch network: a jumper must be
inserted on J7 to disregard the power synchronization signal, which is not used by
the TZtouch network.
Q9.CON Can Engine, Tank and Fuel data be displayed on the TZtouch MFD?
Yes, certain engine, tank and fuel data (up to 4) in NMEA2000 format may be
displayed on any MFD in the Network. The currently accepted data is as follows:
 Engine Speed (Revolutions) (PGN 127488)
 Engine Boost Pressure (PGN 127488)
 Engine Oil Pressure (PGN 127489)
 Engine Temperature (PGN 127489)
 Engine Temperature Status (PGN 127489)
 Engine Warning Status (PGN 127489)
 Fuel Tank (PGN 127505)
 Fuel Flow (PGN 127488 & 127489)
Note: The instance number is used to “map” the engine, tank and fuel flow data.
Instance 0, 1, 2 and 3 must be used (instance 0 corresponds to engine number 1).
3. NavNet TZtouch Compatibility
Q1.COMP Are NavNet 3D networks compatible with NavNet TZtouch?
It is possible to add one or multiple TZtouch MFD(s) to an existing NavNet 3D
network. In this case, TZtouch should only be connected to the NavNet 3D
network using an Ethernet port (do NOT connect TZtouch to the NMEA2000
network in this scenario). All Data Source settings must be adjusted from NavNet
3D (data source selection is disabled on TZtouch when connected to a NavNet 3D
network). When NavNet 3D and TZtouch are connected on the same network,
sensor data (Radar, sounder, etc.) is shared. The Active Route is automatically
synchronized between TZtouch and NavNet 3D, however the Points and Planning
Routes are not.
Note: the SystemID will be different on the NavNet 3D MFDs and TZtouch MFDs,
even if connected to the same network. However, it is possible to link one NavNet
3D SystemID with one TZtouch system ID, similar to the process for linking a
NavNet 3D SystemID to a MaxSea TimeZero serial number.
Q2.COMP Are NavNet 3D DRS and Sounder modules compatible with TZtouch?
TZtouch is compatible with all existing DRS Radars and DFF1/DFF3 fish finders. A
software update for the DRS must be performed by a Furuno dealer to be
compatible with TZtouch in order to support Auto-IP. As described above in
Q8.CON a jumper must also be installed inside the Power Supply Unit. Additionally,
DIP switches inside the DFF1/DFF3 may need to be adjusted (“Down-Up-Up-Down”
to have a fixed IP address).
Q3.COMP Are NavNet 1/vx2 systems compatible with NavNet TZtouch?
It is not possible to connect NavNet 1 or vx2 display to a TZtouch network.
Additionally, BBFF1/BBFF3 black box sounders are not compatible with TZtouch.
