6.4.4.2 NMEA DF Remote
It is possible to operate the RT-800 direction finder remotely using the NMEA communication
protocol. For this purpose, a control unit (e.g., ECDIS) can be connected to the NMEA
interface of the DCU.
Additionally, by choosing the combination “COM3/ LAN”, the NMEA sentences will be also
sent via the LAN connection (s. Fig. 141, position 3).
Caution
If communication ports, other than the default port (COM3), are not used, they will appear as
hotkeys in the dialogs (as possible ports to use for the NMEA remote communication).
Nevertheless, the communicatoin port COM3 is internally connected to MOXA for remote
control purposes.
Please do not:
•
adjust other COM-ports for remote control.
•
use COM3 for purposes other than remote control.
•
disconnect MOXA, if MOXA is used for remote control.
Note
By default, the “Autotalk” mode is activated, which means that NMEA sentences of the
direction finder are sent out cyclically with a fixed time period of 250 ms. The “Autotalk” mode
can also be deactivated per corresponding NMEA command (s. NMEA-Protocol Description
RT-800).
Configure the interface settings for remote control of the direction finder in this menu item.
o
Press the button “OK” or hotkey “Edit Value”, while the setting “NMEA DF Remote” is
marked (s. Fig. 139).
Following sub-menu will appear (s. Fig. 141).
