s , including LEDs, Halogen lamps, and can even ring telephones.

II.RC4 Series 3 Harmonized devices can also control hobby servo motors that are commonly used in puppetry and can also be used in costumes and props.

III. Example: How to spin a servo motor using a W-DIMm3, configured using OneTouchOneTouch™RC4 OneTouch™ uses DMX channel levels to represent channels and curves, which are then adopted by a dimmer when a single small button is pressed. Back in 1993, James David Smith, chief product designer at RC4 Wireless, envisioned a day when wireless dimmers would be so small that there would be no room for rows […]

and a lighting console

A. The W-DIMm3 is a three channel dimmer

B. It is patched to a Wireless Solutions W-DMX transmitter

C. DMX data to the transmitter is coming from a lighting console

D. The RC4 OneTouch mode allows users to access extended dimmer curves

1. A DMX level of 28 selects servo motor clockwise rotation

2. A DMX level of 29 selects servo motor counterclockwise rotation

a. Gearing and actual direction can vary with servo motor manufacturers

E. Bring up your intended servo control DMX channel

1. Set that channel to a DMX level of 28

2. Using a small tool like a paper clip, press the Set C ButtonSet C ButtonAll RC4 dimmers have Set buttons for each individual dimmer output. The third button is the Set C button. On a 2-channel device these are Set A and Set B buttons. A 4-channel device adds Set C and Set D. The most common use of the Set button is to assign a DMX channel and dimmer […]

he dimmer on the RC4 W- DIMm3 that is connected to the servo motor

a. Make sure that the control line from the servo is plugged into the negative side of the correct dimmer output

b. Test the servo direction using fader

c. To change direction of the servo motor, the process is the same, but using a DMX level of 29
