2. RK-433-RC Development Kit Setup
Before operating your RK-433-RC development kit for the first time, initial setup must be completed.
2.1. Hardware Setup
Please refer to Figures 2 and 3 for assistance with the following.
2.2. SecureFOB™ / Receiver Learning
The SecureFOBs™ and receiver evaluation board utilize KEELOQ™ encoder (HCS300) and decoder (HCS512)
hardware from Microchip Inc. These rolling-code coders implement a proprietary algorithm that provides a high
level of security to the transmission.
The SecureFOBs™ included in the kit should already be “learned” to the receiver evaluation board. If a new
KEELOQ™-based receiver is introduced, a learning process must be completed, pairing a transmitter with a

Plug only one receiver module into its proper socket in the receiver evaluation board. The sockets
are labeled in the PCB silkscreen.
Ensure the jumpers on JP1 matches the voltage rating of a selected receiver (3V or 5V). The
following table lists the correct jumper setting for each module.
Table 1, Voltage Settings for Receivers
Make sure to populate only one receiver at a time.
Apply power to the receiver by plugging in the 9V power supply to the Multi-Receiver Unit (MRU)
power jack.
Install one CR2032 coin cell battery to each SecureFOB™. Use a coin to pry open the plastic case at
the seam. Insert coin cell with flat (positive +) side towards the metal clip. Place PCB back into
plastic housing and snap back together.
