Powering the
TWR-RF-SNAP
AttachtheincludedmicroUSBcable
totheUSBinterfaceontheTWR-RF-
SNAPTowerSystemmodule.Insertthe
oppositeendofthemicroUSBcablein
eitheraUSBportorUSBwalladapter.
Slide the power switch to the right
(towardsthemicroUSBreceptacle).A
smallgreenLED(D5),locatednexttothe
USBport,shouldilluminateindicating
that the Tower System module is
correctly powered. With the power
switch in the far-right position, the
TWR-RF-SNAP can also be powered
by inserting the module into the Tower
System and providing power via the
TWR-ELEVorMCUmodule.Optionally,
with the power switch in the far-left
position, the TWR-RF-SNAP can be
powered via the battery connector in a
stand-alone configuration only.
Using the Default
Application
The TWR-RF-SNAP Tower System
module comes pre-loaded with a
simple application to demonstrate user
interactionwiththemodule.Oncepower
is supplied to the Tower System module,
theprogramwillblinktheredLED.
ThegreenLEDhasbeenconfiguredto
react to user input. Use the push-button
labeled“Switch2”toturnthegreen
LEDonand“Switch3”toturnthegreen
LEDoff.

Download/Install
Synapse Wireless’
Portal
Visitfreescale.com/Tower and select the
TWR-RF-SNAP from the list of available
TowerSystemmodules.Downloadand
install Synapse Wireless’ Portal Software.
Portal is a networking commissioning tool
and integrated development environment
(IDE)forSNAPnetworksoftware.It
allows the user to interact with SNAP
nodes and upload custom programs in
the form of SNAPpy scripts (based on
thePythonprogramminglanguage).Refer
to the lab documents associated with the
TWR-RF-SNAP module for instructions.
Learn more about the
included USB SNAP
Stick
AUSBDongle(theSN132SNAPStick
fromSynapse)wasincludedwiththiskit
todemonstratethewirelesscapability.It
is not only its own free standing node in
the SNAP network, but also provides the
PCandPortalsoftwareabridgeintothe
SNAPnetwork.RefertotheLabTutorials
associated with the TWR-RF-SNAP
Tower System module for more about the
USBdongle.
