DK1000R
315MHZ REMOTE KEYLESS ENTRY RECEIVER
• Remote Monitoring
• Remote Controls
Product Description
The DK1000R is the receiver half of our remote keyless
entry system evaluation kit. It is designed to allow the
user to easily and quickly demonstrate the operation of
the RF2919 in a typical application. Everything needed to
demonstrate a one way receiver is included. The RF2919
is setup to demonstrate a typical keyless entry system
using a rolling code decoder while operating as an
FCC15.231 type device at 315MHz. A battery is included
and the antenna is printed on the circuit board. This unit
is designed to work with the mating transmitter, DK1000T.
