2. Operating the Demo
The Si4010 key fob transmitter and the Si4355 RFStick receiver are the transmitter and receiver devices used in
the one way link demo. This transmitter/receiver pair can be used to evaluate the capabilities of the Si4010
transmitter and the Si4355 receiver.
The first step is to insert the CR2032 battery in the battery holder on the 4010-KFOB-XXX demo board and then
place the board into the plastic key fob case. Next, insert the two AAA batteries in the battery holder on the 4355-
LED-XXX receiver board and turn it on by setting the S6 switch to the “Battery” position. LED4 will light
continuously indicating that power is on and the SRX firmware is running.
When a button is pressed on the key fob, LEDs flash on the receiver boad according to which button was pressed.
In the next table, buttons are named according to their position when the key fob is held with its LED facing
forward.
