Servo Travel Expander

Plug your servo into the flying lead on the Servo Travel Expander. Plug the other End Point Unit lead into the selected channel on the receiver. The servo will operate with full travel. The Servo Travel Expander has two input keys, the increase key and the decrease key. The neutral position can be set and end point positions between 20% and 200% travel can be individually set each side of neutral. SERVO REVERSER SET-UP With the receiver switched off, press and hold the “-“ key and then switch on the receiver. Release the key and the Digital End Point Adjuster will operate in the reverse direction. To revert to the normal travel direction, perform the above procedure with the “+” key pressed. NEUTRAL SET-UP With the stick at neutral, use the increase or decrease keys to move the servo neutral to the required position. The servo will move one step each time the key is released. The neutral can be adjusted over a range of about 10% of travel. Note that the neutral position affects the end point positions so it is advisable to set the neutral first. END POINT SET-UP To enter the end point set-up, press both keys simultaneously for about 1 second. The LED will light to indicate that the end point set-up procedure is active. Release the keys. Move the transmitter stick to its full movement on one side of neutral. While holding it there, press the decrease key. The servo travel end point will reduce. Pressing the increase key will cause the travel to increase. Use the increase and decrease keys to move the servo to the required end point position. Repeat this procedure with the transmitter stick to its full travel on the other side of neutral. Move the transmitter stick from side to side to confirm the correct end point positions. When you are satisfied that the correct settings have been achieved, press and release both keys simultaneously to exit the set-up. Do not hold the keys too long or the system will once again enter set-up. The LED will extinguish to confirm that the operational mode is selected. THE NEW SETTINGS WILL NOT BE STORED UNLESS THE SET-UP IS EXITED. If you wish to change the set points at any time, simply repeat the set-up procedure. SAFETY Please ensure that the selection keys cannot be pressed accidentally while the unit is in use.
