I've installed numerous Micro Commander systems, with up to 4 helms. It's a very reliable & versatile system, and the remote is very handy, includes a P/S momentary switch which can be used to control a bow thruster, or rudder
(if you have an autopilot) (but there's no provision for a rudder
position indicator). The remote is a twin engine
control, so you'd just have to choose one side and ignore the other.
The control voltages are analog DC, there's no noise
producing signals thru the cables
. The actuator units take regular Morse cables
, so can interface with any engine that uses standard control cables.
The control heads used to have a problem with the 'take control' momentary switch wearing out and shorting, disabling the system, but that was upgraded about 4 years ago (retrofit part is available). The mechanisms inside the actuators need a spray of lubricant every couple years, and the mechanical cables must be maintained, otherwise they are pretty much trouble and maintenance-free.
With multiple control stations, one station in control locks-out all others, however, you can take control away from another station by placing the handles in aproximately the same position then holding the take control button for 3 seconds.
The system should be powered from the service battery
bank. If it must be powered from the engine starting battery
, a product like the Newmar Start-Guard
should be used. (Voltage drop from cranking may reset the system and re-activate the neutral start lockout.)
