2.29.2 How to preset antenna and display combinations
You can preset the antenna and display combinations for each antenna and display
in the radar system. As an example, the procedure below shows how to select the no.
1 antenna unit for the no. 2 display unit.
1. Open the menu then select the [8 INITIAL SETTING] and [5 ANT SELECT]
menus.
2. Select the display unit for which to select an antenna (at the next step). For exam-
ple, select [DISP2] to select the no. 2 display unit.
3. Select [ANT 1] and [M].
4. Repeat steps 2 and 3 to set other display and antenna combinations.
5. Click [STORE INTER-SW] and select [YES] to save your selections.
6. Close the menu.
Antenna selection considerations
• An antenna unit cannot be controlled from multiple display units. Select one Master
display unit for one antenna unit. If two antenna units are set as masters, the display
last-set as master becomes the master and all other displays are automatically
changed to slave.
• An antenna unit without a Master display cannot be selected on the sub display
units. If there is no antenna unit set as master, the lowest number display is auto-
matically set as master.
• If the Alert 750 “EXT Radar COM Error” appears, do one of the following as appli-
cable:
• If only your antenna is not displayed on the [ANT SELECT] display, the LAN line
in the Processor Unit may be faulty. In this case, use the standalone mode.
• If the antenna that was in use does not appear on the [ANT SELECT] display, the
LAN line in other Processor Unit may be faulty. In this case, see the preceding
page for how to select a different antenna unit.
• When the Network fails, the Interswitch does not work, but standalone operation is
possible.
• Radar functions are controlled independently, dependently or commonly depending
on selection as Master or Slave (see the table on the next page).
• When connecting with the FAR-2xx7 series radar, the maximum number of ac-
quired targets ([NUMBER OF TT]) should be set to 100 in the [RADAR INSTALLA-
TION] menu. For details, see the installation manual.
• Do not use the interswitch function when the icing prevention feature (see
section 2.40) is active.
Compatibility of display and operation
• When connecting with FCR-2xx9 series radar
The FCR-2xx9 is compatible with the FAR-3xx0 in display and operation. For exam-
ple, when switching the antenna from FAR-3xx0 to FCR-2xx9, the image for FCR-
2xx9 is displayed on the screen and each function is operative, and vice versa.
