Each keypadCUE-55 is identified by an **ADDRESS**. This ADDRESS must be **unique **within the units connected to one RS-485 (CUEwire) line.

- The ADDRESS can be set in the range **2 to 30**.

- Default ADDRESS is **2**.

- The address set in the keypad must match the address in the Cue Visual Composer project configuration.

The address of the keypadCUE-55 is stored in the internal flash memory. 

For **modification of the address** do the following:

- Unplug the connection cable.
- Press and hold the left andright bottom buttons and plug the connection cable. This will bring the keypad into the **address setting mode**. The right bottom LED will blink. You can now release both buttons.
- The LEDs for button 1 - 7 indicate ADDRESS in binary code – Button 1 bit 0, Button 2 bit 1 etc… Push buttons to toggle address bits to the requested value of ADDRESS (see table below).
