•
•
•
•
•
•
•
•
•
•
1-Rapid Development Case.
1-Rapid Development Utility and Documentation CD.

Kit Setup
•
•
Insert the AAA batteries into the evaluation PCB, observing the correct polarity.
Insert an EVM into one of the evaluation boards, observing the correct orientation (see later in
this document). The correct orientation of the EVM is with the antenna connector closest to the
edge of the evaluation board. Make sure the module is seated fully and correctly.
Insert the other EVM into the other evaluation board, also observing the correct polarity.
Connect antennas to EVMs.
Connect evaluation boards to computers. If using USB communications, populate USB jumpers
and remove RS-232 jumpers. If using RS-232 communications, populate RS-232 jumpers and
remove USB jumpers.
Install the RK-Wi.M900X Windows software. If already installed, skip this step.
Run the RK-Wi.M900X software, select 2400 baud operation and navigate to the “Wireless Chat”
tab.
Power-On both evaluation boards, verifying that the version/copyright information is echoed to the
screen from both modules.
Chat back and forth between evaluation boards, verifying that serial and RF communications are
successful.
IMPORTANT NOTE FOR HYPERTERMINAL USERS:
See section 5.1

3 Using the RK-Wi.M900X Evaluation Software
The software supplied with the RK-Wi.M900X RadKit is used to read and set the volatile and non-volatile
registers with the Wi.M900X module. Refer to the Wi.M900X Users Manual for more information on the
register settings.
3.1
COM Port Setup and Selection.
Upon starting the RK-Wi.M900X evaluation software, you will be
presented with a COM port selection dialog box. If you are using the
USB interface, make sure that the evaluation board is already
connected to the computer via the USB cable before you start the
software. This will ensure that the virtual COM port which is assigned
to the USB to UART bridge controller by Windows is visible in the
COM port selection list.
The first time you start the RK-Wi.M900X evaluation software, the
Baud Rate should be left at 2400 baud, since this is the factory default
baud rate setting for the module.
Tip:
There is no way for the RK-Wi.M900X evaluation software to
detect which baud rate the module is set to. If you have changed the
Non-Volatile Data Rate register, you will have to select the baud rate
you set this register to when you start the RK-Wi.M900X evaluation
software.
