Introduction
The RC2300/RC2301 Zigbee-ready modules provide a very compact solution for a wide
range of wireless network applications. The kit can be used to develop and test proprietary
protocol applications as well as ZigBee-based applications.
The RC2300 kit is normally shipped with an embedded firmware for range testing, while the
RC2301 kit is shipped with a location demo firmware.
The kit can be used for development of a customer’s proprietary protocol, or any Zigbee
network implementation ported to the RC230x hardware platform. In this case the user would
re-flash the modules with his own application, and the program/debug interface could be used
for debugging also.
The RC2300DK Demonstration Kit is designed to make it easy for the user to evaluate the
module and/or develop an application very quickly. With the RC2300DK Demonstration Kit
you can:
•evaluate the RF performance of the modules
•develop your own application interfacing the modules
•build a prototype of your application
This User Manual describes how to interface the Demonstration Kit and provide detailed
documentation for the Demonstration Board and its onboard resources.

Demonstration Board
The Demonstration Kit includes two Demonstration Boards. The Demonstration Boards
contain the RC230x module and associated support circuits. The board provides an a serial
port driver circuit for RS232 and the 9-pin D-Sub connector, DEBUG interface for
programming and debugging, access to all digital and analogue I/O, push-buttons, LEDs, a
potentiometer, a light sensor and an accelerometer as well as a voltage regulator.
Configuration jumpers and connectors make it easy to interface the RC230x with various test
equipment or the host used in an application. Not all components are needed in an actual
application. Please see the datasheet for a typical application circuit.
Figure 1: RC230xDB Demonstration Board
The SMA connector layout pattern is not used on this board (and is not connected to the
module antenna output) as the module contains a chip antenna.
Typical range measured between two boards in line-of-sight is 110 meters when the chip
antennas are oriented vertically (or parallel). Indoors a range of 10-30 can be expected,
depending on the materials in walls and floors.

Power supply section
The board contains a voltage regulator. You can choose between applying a 4-10V
unregulated supply voltage at the DC jack (like the battery eliminator included in the kit), or
the screw terminal where a battery pack or some other supply can be connected. The on-
board regulator drops the voltage to 3.0V. A green LED will light up the board is connected to
a power source.
Input supply voltage range is 4 – 10 V. A series diode protects the circuit against wrong
polarity.
The current supply to the module is through the jumper at P13, pin 3 and 4. An ampere meter
can be connected here in order to measure the DC current drawn by the module. Remove the
jumper and replace by an ampere meter in order to measure the current. The location of P13,
pin 3 and 4, are shown in the figure below.
Figure 2. Module current consumption measurement
Note: To ensure proper Power-On Reset (POR) the wall socket end of the AC/DC battery
eliminator should be inserted first, and then the DC-jack into the board. If the VCC power-on
rise-time specification is not met, the board may need the RESET to be activated to ensure
correct start-up.

RS-232 interface
The Demonstration Board provides an RS232 driver circuit. The serial port is configured as a
data modem and a 1:1 cable should be used to connect the board to the PC. The RTS/CTS
handshaking pair is also provided, so that hardware handshaking may be used on this port.
The serial port (RXD and TXD) and handshaking signals can be HW enabled by doing the
following hardware changes:
•Insert jumpers at P13 to connect RXD and TXD to the RS232 driver
•Insert jumpers at P13 to connect CTS and RTS to the RS232 driver if hardware
handshake is to be used
P13 is used to set jumpers to connect the module UART interface to the RS232 PHY driver.
Normally the jumpers connecting RXD and TXD are installed, and provide UART
communication with a PC without handshaking. With the jumpers removed the modules RXD
and TXD can easily be connected to a host using logic levels, for instance a microcontroller or
external development board. The table below shows the pinout and signals at P13.
There are two LEDs indicating traffic activity on the UART. A green LED is connected to the
RXD line, and a red LED at the TXD line.

Connectors
The Demonstration Board is furnished with many connectors for easy access to all module
signals.
P5 bring out supply voltage, the DEBUG interface, a spare digital data I/O signal (Port 2) and
the RESET line.
P6 brings out digital and analogue I/O (Port 0). A 2.54 mm pitch pin-row can be mounted at
P6 if convenient.
P7 brings out digital I/O (Port 1) and the 32 kHz oscillator clock pins. A 2.54 mm pitch pin-row
can be mounted at P7 if convenient.
P8 is the DEBUG interface (pin compatible with the TI / Chipcon SmartRF04DB DEBUG
connector).
P9 is a connector for jumpers to connect/disconnect the on-board analogue sensors
preventing them loading the pins when not used.
P10 is a connector for jumper to connect VCC from the demonstration board back to the
programmer/EB.
For detailed signal description, please refer to the pinout shown in the data sheet.
Push buttons
The Demonstration Board is furnished with 6 push buttons connected to the following I/O
signals:

Accelerometer
The accelerometer can be used measure movements in 2-axis, it can also be used for tilt
measurement by measuring the earths gravitation. Accelerometer self test can be initiated by
shorting test point T1 to ground. The accelerometer has a 20 ms start-up time after power on.
See the Analog Devices ADXL321 datasheet for details about the accelerometer.

Potentiometer
The potentiometer is connected as a voltage divider between supply voltage and ground.
Turning the knob clock-wise gives maximum voltage.
Light sensor
A light dependent resistor (LDR) measures the light level and gives an analogue signal that
can be measured by the RC230x A/D converter. The light sensor resistance ranges from 5K
(light) to 20M (dark), and is connected a voltage divider together with a 200k Ohm resistor to
the supply voltage. See the Silonex NSL-19M51 datasheet for details about the LDR.

Debug and programming interface
The Demonstration Board provides a DEBUG interface used to program firmware into the on-
board module and for debugging the code. The DEBUG interface is compatible with the
DEBUG interface at the Texas Instruments / Chipcon SmartRF04EB board. This board and its
associated software are available from TI / Chipcon. The table below shows the P8 SOC
debug connector pin-out. See figure Figure 4.
Another option for programming is a third party programmer as FlashPro-CC from Elprotronic,
as shown in Figure 5
Below is shown how to connect the RC2300DB to the SmartRF04EB.
