MRW12 Turret Servo Controller MKII

Features

Most standard proportional radio control servos can be controlled.  (Not retract servos.)

Servo travel up to 200% can be selected.

Independent stop points may be set each side of neutral.

Transit times between approximately 3 seconds and 18 seconds for 150% travel may be selected.

The servo start-up position can be set.

Transmitter stick operating direction can be selected.

The LED lights when the servo is at neutral.

Instructions

Plug the flying lead on the Digital Turret Controller into the selected channel on your receiver.  Connect the servo to the Digital Turret Controller.  Switch on the transmitter and then the receiver.

Operation

Movement of the transmitter stick to one side of neutral will cause the servo to move in one direction.  The movement will stop if the stick is returned to neutral.  Movement of the stick in the opposite direction will cause the servo the move in the opposite direction.  In this way, the servo can be positioned anywhere within its travel range.  As an aid to set-up, the LED will light while the servo is at neutral.  All servos vary and because of the expanded travel the servo can be driven against its stops.  Do not leave the servo driving against its stop or damage to the servo may occur.

Stop Point Set

Use the stick to position the servo at the required stop point on one side of neutral.  With the stick at neutral, press and release the “+” key.  The servo will not move past the position set.  Repeat this with the servo on the other side of neutral to set the other stop point.

Stop Point Clear

Use the stick to position the servo at the stop point to be cleared and with the stick at the extreme, press and release the “+” key.  The servo will move past the stop point and the stop point will be cleared.

 

Transit Speed

Press and hold the “+” key and then switch on.  The LED will repeatedly flash four times and then pause.  Each flash represents a unit of delay and the servo will move more slowly as the delay units are increased.  When the required number of flashes have been seen, release the key.  The servo will operate at the selected speed.

Servo Start-up Position

Position the servo at the required start-up point.  Press and release the “-” key.  The selected position will be used on the next start-up.

Travel direction

Press and hold the “-” key, switch on and then release the key.  The travel direction will toggle between forward and reverse each time this action is performed.

The unit remembers all settings and it is only necessary to perform set-up initially and when making adjustments.

SAFETY

Please ensure that the selection key cannot be pressed accidentally while the unit is in use.

Operating voltage 4.4v to 6.3v (4 cell or 5 cell NiMh Pack) HV version available on request.
