I. All RC4 4-channel dimmers act the same way, even though there are different sizes and have different label colors

A. Buttons are behind slots

B. Colored LED indicators are behind round holes

C. Associated buttons and LEDs are close to each other

1. For example, the SetA button is immediately above or below the DimA indicator

II. The physical dimmer size is related to power handling

A. Larger devices handle more current

B. All processes are the same for all 4-channel RC4 units, including:

1. Assigning DMX channels and dimmer curves

2. Selecting modes

3. Settings PWM frequency

4. Settings RC4 Digital Persistence time

C. Videos demonstrating techniques on a specific 4-channel device can be used on all 4-channel devices

1. All of the same steps apply

2. The functions and user interfaceUser interfaceThe user interface (UI) is the physical hardware on a device that users interact with to configure settings, enable and disable features, see operational status, and more.  The user interface on most small RC4 devices is comprised of recessed buttons and small LED indicators.  More complex devices may use rotary controls, touch screens, and more.

D. For example, a technique demonstrated on the DMX4dim is the same when done on a DMX 4dim-500
