6. Z-Location Demonstration
6.1. Switches and LEDs
In this, and other Z-Stack documents, references are made to switches and LEDs located on
evaluation boards. These devices are used to control certain Z-Stack features and display status.
Certain procedures require user input via switches, commonly referred to as SW1 through SW5.
The SmartRF04EB boards have a 5-position joystick, designated U400, which provides these
switch inputs as shown in the table below. Pressing the joystick toward the U400 label (up
position) activates the SW1 input. Switch inputs SW2 – SW4 result from pressing the joystick to
the right, down (away from U400), and left positions, respectively. SW5 occurs when the
joystick is pressed straight down when in the center position.

Z-Stack sample applications display various operational status LEDs, commonly referred to as
LED1 through LED4. The SmartRF04EB has 4 colored LEDs, designated 1 - 4. The CC2430EM
module does not have connections to the red LED (2) or the blue LED (4). Therefore, LEDs 1
and 3 are used to provide all LED indications from Z-Stack applications as shown in the table
below.
