Chapter 1. Quick Start

1.1 INTRODUCTION

This section provides the user a quick step-by-step instruction guide on how to set-up

the MCP2030 Bidirectional Communication Demo Kit.

1.1.1 Transponder Unit

Connect power to the Transponder unit by inserting a 3V NiHM (CR2032) battery to the

battery holder in the bottom side of the Transponder. When the Transponder is

powered on, it is waiting for a 125 kHz low frequency (LF) command from the Base

Station unit. On the PCB, there are three LF antenna coils: One large air-core coil on

the bottom side and two ferrite-core coils on the top side. These three coils detect

125 kHz low frequency (LF) signals from x, y, and z directions. The Transponder also

has a SAW (Surface Acoustic Wave) based UHF transmitter. A rectangular loop trace

on the PCB is the UHF antenna. The Transponder has two LED diodes. A green LED

(D6) will blink when the Transponder receives a valid LF command, and a red LED (D7)

will blink when it transmitting an UHF response.
