MCP2030 Bidirectional Communication Demo Kit User’s Guide
DS51637A-page 6
1.1.2
Supply power to the Base Station unit with a 9V - 18V power supply. As soon as the
power is supplied, the LED D2 will light on, and the unit starts transmitting an LF
command.The unit also waits for the responses from the Transponder at any time,
except during the transmission of the LF command. When the unit receives a valid
response from the Transponder, the LED D3 will blink and the received Transponder
ID and RSSI (Received Signal Strength Indicator) value will be displayed on the LCD.
1.1.3
When the two units are powered-on, they will communicate by themselves. The Base
Station sends a 125 kHz LF command and the Transponder responds to the command.
When the Transponder is placed within about 2 meters to the Base Station unit, the two
units may have a successful communication with each other and the Base Station unit
will display the received Transponder ID and RSSI value on the LCD. This is called a
bidirectional communication. User can test the RSSI by moving the Transponder within
the Base Station’s LF field. The RSSI value will increase as the Transponder comes
closer to the Base Station antenna and decrease as moves away from it. The two units
are communicating with each other as long as the boards are powered. You can also
test one directional communication from the Transponder to the Base Station unit by
pressing button switch (SW3 or SW4) on the Transponder. The range of the one
directional communication is about 20 meters.
This MCP2030 Bidirectional Communication Demo Kit shows you how to create a
smart hands-free bidirectional communication system using the stand-alone MCP2030
and microcontroller. All MCU firmware used for both the Transponder and Base Station
units are included in the CD ROM provided with the MCP2030 Bidirectional Communi-
cation Demo Kit. The user can easily modify the firmware for their own applications.
