CHAPTER 5: ADDRESSING
5.1 ADDRESSING BUTTONS
5.1.1 ADDRESSING RULES
The ADDRESS of the buttons and LEDs of the keypad can be set in the range 0 to 207. The default button panel ADDRESS is 1.
The BUTTON_ID transmitted by the panel is the LINK number used in the programming for button identification. The BUTTON_
LED_ID is LED identification for ButtonLed commands. Both values depend on the button (LED) position and on a keyboard
ADDRESS too. BUTTON_ID is calculated according to the formulas described below.
BUTTON_ ID = (32 * ADDRESS) + Button Code
BUTTON_LED_ID = (32 * ADDRESS) + Button LED Code
The lowest BUTTON_ID is generated by the button in the upper left corner; the highest BUTTON_ID is generated by the button in the
lower right corner.
Button Code = 1 Button LED Code = 1
Button LED Code = 8 Button Code = 8
FIGURE 5-1. BUTTON ID RANGE
In the table below, Button ID range for some addresses is shown.

FIGURE 5-2. KEYPAD BUTTON ADDRESSING SWITCH
1. Push the keypad button addressing switch on the rear side of keypad using a small screwdriver or wire; backlight LEDs are
switched off to indicate Set Address Mode.
2. Button LEDs 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.
3. Push the keypad button addressing switch to save an ADDRESS to non-volatile memory and to enter keyboard Standard Mode.
Backlight LEDs switch on to indicate Standard Mode.

CHAPTER 5: ADDRESSING
5.1.3 TROUBLESHOOTING
Flashing backlight LEDs indicate a non-volatile memory ERROR. Try the Power OFF – Power ON sequence to restart the device and
set the ADDRESS again.
5.2 ADDRESSING THE BUILT-IN IR RECEIVER
5.2.1 ADDRESSING RULES
You can add an offset to a BUTTON_ID sent by the control panel using the IR receiver built into the keypad. It can be very helpful in
multi-room installation—the same ControlBridge can be identified in each room. That means one panel can initiate different actions
in different rooms—see an example in the picture on the next page.
