used to issue messages into the network, and the other nodes in the network are using the
dongle for addressing packets to the PC application.
It's recommended to use a SmartRF04EB for the location dongle, since this board gives easy
access to a UART connection. The dongle node can use either a CC2430 or a CC2431 RF
chip
The Z-Location Engine includes a flash download function, which makes it possible to
download an already generated hex file to a connected development board. Please note that
flash programming can only be done with use of a USB cable. How to perform flash
programming is described later in this manual.
9.2 Installation
The Z-Location Engine is distributed as an executable installation file. This file can be
downloaded from the CC2431 product page on www.ti.com. The installation file will add an
item to the start menu. The Z-Location Engine application can be started by clicking [Start] ->
[Programs] -> [Chipcon] – [Z-Location Engine].
9.3 Connections
The SmartRF04EB should be powered either from a power supply or from USB. The PC must
be connected to the SmartRF04EB using a UART cable
is operating is over the UART. If a USB cable is connected, this makes it possible to
download firmware directly from the Z-Location Engine PC application. The USB can in
addition be used for downloading and debugging the dongle node from e.g. the IAR
embedded workbench development environment.

A UART cable is often called RS-232 cable, serial cable, or null-modem cable. It connects to
a serial port on the PC and to the D-SUB connector (P200) on the SmartRF04EB.
