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.)
