SmartWinch Auxiliary Adjustments

Transmitter On/Off Method

For D revision 3 models when using AM or FM radios

For description of these options click here. Please note that SLT is only available as single ended in D series 3. 

Before starting

  •   Winch is OFF
  •   Winch connected to receiver (Rx)
  •   Transmitter (Tx) OFF
  •    End points should be calibrated to this Tx previously for best results 
  •    Tx stick in desired position. Select close hauled for minimum, full out for maximum or any intermediate position as desired.
  •    There is no need to remove drum or sheets. The winch will not drive while making these adjustments

Option entry point table

 Adjustment  Time (seconds)  Sound Signal
 DEC  14  3 rising tones
 SLT  17  2 quick beeps
 SPD  20  3 quick beeps
 DB  23  4 quick beeps








  1. Turn winch on and wait for the sound signal for the desired option then turn Tx on immediately (within 2 seconds).

    A single long beep will sound indicating the Tx stick position has been sampled.
  2. Turn Tx OFF.

    A 3 quick beeps will sound indicating the new setting has been saved.

    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 optimisation of Tx fine trim control. The default setting is 10 microseconds.
