Ferry Mode
The TZT12F/16F/19F as well as TZTL12F/15F/TZT2BB v7.01 in combination with a DRS series Radar
sensor and a compatible SATELLITE COMPASS such as the SCX-20, SC-33, and SC30 can take
advantage of the Ferry Mode. On shuttle ferries with one Radar and one heading source, the heading
output from an SCX-20, SC-33, or SC30, as well as Radar heading of the sourced DRS, is offset by 180°
when pressing an external event switch connected to the MFD.
Target Boat Types
Simplified double ended ferries with one
Radar and compass on top, such as road
ferries, are the main target of this
function.
Compatible Sensors
The process of output heading offset utilizes the NMEA2000 standard PGN
: 126208 (Command
Group Function)
to send a command to a compatible SATELLITE COMPASS and
proprietary PGN:
130818
to edit the heading offset value. The SCX-20, SC-33, and SC30 support these PGNs. Any DRS
Radar sensor compatible with the TZT12F/16F/19F can be used as the Radar sensor.
Interconnection and Setup
(1)
Network the TZT12F/16F/19F with DRS series via Ethernet and SCX-20 or SC-33/30 via NMEA2000.
(2)
Connect an external switch to the TZT12F/16F/19F, or TZtouch2 MFD.
