Interesting, maybe Lemar is "rebranding" whoever is making the Vetus.
After replacing a $200+ little joystick controller on a customer's Vetus with a new one, I took the old one apart. What could cost $200+ in a box that is basically just an "on/off" switch and a SPDT Joy Stick switch?
Amazing there was a whole circuit board inside with way too much stuff to be a simple switch setup.
So that is most probably why your "old" classic "switch-to-relay" system does not work with the "new, improved" considerably more expensive "black box" which in essence is the controller with the power relays in it to activate the thruster motor
. This seems to be a trend in the industry to make "tried and true" simple systems into mega-complicated stuff that you cannot service
- only buy a new replacement. . .
