NavNet TZtouch2 Installation Checklist
NavNet TZtouch2 Network Installation
Connect all TZtouch2 MFDs to the Ethernet Network. If a HUB101 is used,
set the internal HUB DIP switches to OFF (HUB101 DIP switches are OFF
by Default). TZtouch2 MFDs do not use power synchronization.
Using a generic Ethernet Hub/Switch with TZtouch2 is also acceptable.
Connect all TZtouch2 MFDs to a proper NMEA2000 backbone using drop
cables (18 feet or less).
Note: TZtouch2 MFDs do not have an internal terminal resistor that can be
switched ON or OFF. All connections to the NMEA2000 backbone must be
"drop" connections (18 feet or less).
If a DRS Radar is included as part of the system, DO NOT connect any
NMEA2000 Sensors to the CanBus Port on the DRS. The DRS CanBus port
is currently not compatible with TZtouch2 MFDs. If retrofitting a TZtouch2
MFD to an existing DRS, any NMEA2000 sensors directly interfaced to the
DRS must be disconnected. If necessary, you may reroute these sensors
to the NMEA2000 backbone which is interfaced directly to the NMEA2000
Port on the TZtouch2 MFD.
If using an external sounder in addition to the internal RezBoost Sounder,
make sure the DFF1, BBDS1, DFF3 and DFF1-UHD are set up for "fixed IP
addresses" (See Appendix 1, 2 and 3 for additional information)
If a Radar is part of the network and a PSU012 or PSU013 is installed,
connect the Radar Ethernet and Power cable to the PSU, then connect the
second Ethernet port of the PSU to the Ethernet Hub/Switch or directly to
the TZtouch2 MFD. Make sure a jumper is inserted inside the PSU on J7.
This allows the PSU to start without a power synchronization signal. (See
Appendix 4 for additional information)
Note: It is OK to bypass the Ethernet connections on the PSU and plug the
Radar RJ45 connector directly into the Ethernet Hub/Switch if the cable run
allows. This will reduce the need for an additional cable.
