Installation DL2 Doppler Speed Log System
APPENDIX 4: CONNECTING 2 SYSTEMS
Some vessels require 2 systems connected together. It is currently not possible to have both systems
running at the same time, however it is possible to get the systems to connect together such that both
are powered, and by setting one unit in standby (Cong menu) The other will wake up by itself.
To implement this the NMEA output of a CU-M001 graphic display on one system, must be connected
to the input of the display of the other system. i.e cross over of NMEA.(pin 9-11, 10-12)
In addition the option ‘Parallel systems’ must be turned to ‘ON’ on the screens with NMEA connec-
tion.
In this mode all system parts will be powered. and when one system is placed in standby will be mut-
ed, and all IO will sleep. When it is woken ( by touching the screen) it will command the other unit to
go into standby. THis reduces the time of changeover to a few seconds
