RMGSwitch BEC Method
D models revision 3
Auxiliary Adjustments
For description of these options click here. Please note that SLT is only available as single ended in D series 3.
Before starting
- The boat must be wired as per RMGSwitch BEC instructions.
- Boat and transmitter (Tx) is on and winch is responding normally to Tx stick control.
- When instructed to "press the button", the button must he held down for less than 1 second.
- When instructed to "press and hold the button", the button must he held down for the specified time.
- When instructed "turn the boat off", press and hold the button for more than 2 seconds and less than 3 seconds. The LED will go off at 2 seconds and turn on again at 3 seconds.
- End points should be calibrated to this Tx previously for best results.

Procedure
- Move Tx stick to close hauled for minimum rate, full out for maximum rate or any intermediate position as desired.
- Press and hold the button then release immediately the LED turns off for the second time.
The winch will then give its startup signal and start the setup mode countdown.
- Ignoring the 3 quick beeps signal at 10 seconds, press the button when the winch gives the sound signal according to the desired setting from the table above. (within 2 seconds).
A single long beep will sound indicating the Tx stick position has been sampled.
- Press the button after the long beep.
A 3 quick beeps will sound indicating the new setting has been saved.
- Turn the boat off.
Note: This procedure can be performed as often as you like. There are no special requirements for deleting old settings before performing the procedure. Old settings are automatically replaced when new settings are made.
Auxiliary Adjustment Options
Deceleration Rate (DEC)
The time taken to decelerate from full speed to stopped can be adjusted. At minimum, deceleration takes around 1 second. Maximum is around 0.1 seconds. Depending on supply voltage used, the SmartWinch may over shoot and hunt so experimentation is advised. The default setting is 70% of maximum.
Scaled Linear Travel (SLT)
Travel response to the first 25% of Tx stick movement out from close hauled is adjustable from 1:1 at minimum to a maximum of 4:1. The default setting is 1:1. For example, if 50% is selected, each increment of the first 25% of the stick range results in half the travel of the default setting. This feature is similar to exponential travel adjustment in some transmitters. However scaled linear has the advantage of consistent incremental travel over the first 25% of stick movement whereas exponential is constantly varying.
Speed (SPD)
The maximum speed can be reduced. This feature is included for non sailing applications where a certain speed is required.
Deadband (DB)
Input dead band is the amount dithering in the Rx signal that a servo can tolerate without responding to by constantly jittering. This is now adjustable from 2 to 15 microseconds. Dead Band adjustment allows the optimization of Tx fine trim control. The default setting is 10 microseconds.
