As per above example, you may save modified settings as user default by pressing Save, and
later on return to factory default at any time by selecting the button “Reset Harbour” to “Fac-
tory default”.
TXRX interswitch menu (standard)
Pressing TXRX and Interswitch button (“Main menu with ECDIS” on page 52), normally
labelled “TXRX n mode”, where “n” is the number of the selected transceiver and “mode” is
“Master” if master or “Slave”, the “TXRX AND INTERSWITCH MENU” (above) will be displayed.
In the first group of buttons, on the right, starting from the upper side the operator has the
possibility to switch between Master and Slave mode, turn on or off the Performance Monitor
and the Power Boost functions (where available) and visualise the TXRX data. The last button
of the group displays a new window with all the available data regarding the status of the
transceiver. The second group of buttons (Switch buttons), on the left, allows selecting the
desired transceiver. The group could be from one to four buttons, according to hardware and
software configurations.
Master/Slave
By means of the first button of the right column the operator can set the radar system to be
Master or force the operating display in Slave mode.
In Slave the TXRX is not controlled by the operating display. If the transceiver is controlled by
another display or if it is in local mode, it is possible to use the radar in a kind of “read-only”
mode. Switching the button to Master mode, the display requires being master, and if pos-
sible the TXRX can be fully controlled by the operating display. The status of the transceiver
operating mode is continuously displayed on the TXRX Interswitch button (page 77). In
case the TXRX Interswitch button is flashing in yellow color, the display is asking to be master,
but the transceiver is controlled by another display with priority.
Performance monit or on/off
By means of this button the Performance Monitor function can be switched on and off.
The Performance Monitor facility (“TXRX interswitch menu (standard)” on page 77) is
provided for checking the performance of the transceiver, waveguide and antenna. The best
way to use this function is to set the range scale at 24 NM, tune the radar and adjust the gain
control at about 90%. In this condition an intensified noise ring, positioned approx. at 24 NM
should appear. The distance of the ring from the centre is forward proportional to the TXRX
transmitted output power. When the Magnetron has decreased 10 dB in peak power, the
ring’s distance will decrease down to about 12 NM range.
