2. Development Kit Setup
•Insert the AAA batteries into the evaluation PCB, observing the correct polarity.
•Insert a Wi.M868X-EVM-RTM module into one of the evaluation boards, observing the correct
orientation (see later in this document). The correct orientation of the module is with the antenna
connector closest to the edge of the evaluation board. Make sure it is seated fully and correctly.
•Insert the other Wi.M868X-EVM-RTM module into the other evaluation board, also observing the
correct polarity.
•Connect antennas to Wi.M868X-EVM-RTM modules.
•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.M868X-RTM Windows software. If already installed, skip this step.
•Run the RK-Wi.M868X-RTM 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 4.1

3. Using the RK-WI.M868X-RTM Evaluation Software
The software supplied with the RK-Wi.M868X-RTM Development Kit is used to read and set the volatile and non-
volatile registers with the Wi.M868X-RTM module. Refer to the Wi.M868X-RTM Users Manual for more information
on the register settings.
3.1. COM Port Setup and Selection
Upon starting the RK-Wi.M868X-RTM 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.M868X-RTM evaluation software, the Baud
Rate should be left at 2400 baud, since this is the factory default baud rate
setting for the module.
Tip: The RK-Wi.M868X-RTM evaluation software does not auto detect the
baud rate of the module. 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.M868X-RTM evaluation software.
Figure 1: COM Port Setup
3.2. Wireless Chat Page
The Wireless Chat page in the RK-Wi.M868X-RTM evaluation software demonstrates the capability of the
Wi.232TM to be used as a wireless communications link. The Rapid Development kit works as a wireless chat link
with no register changes required, out of the box.

To Use Wireless Chat: Type a message in the lower text field and press Enter. The text you typed will be
displayed on the remote system, prefixed with a Node Identifier if you specified one.
Figure 2: Wireless Chat
3.3. Non-Volatile Register Page
The Non-Volatile Register
page in the evaluation
software allows you to
change the default settings
which will be loaded when
the module is powered on.
It is important to note that
data rates in excess of
19.2kbps cannot be
achieved in LP mode due
to bandwidth limitations.
Tip: If you change the
Non-Volatile Data Rate
setting, you will have to
select the baud rate you
set this register to when
you start the RK-
Wi.M868X-RTM evaluation
software.

3.4. Volatile Register Page
In this page, you can
change the Volatile settings
of the module. Values
programmed into these
registers are lost of power-
down. The page also
provides a means of
switching the receiver and
transmitter on and off,
setting receive and transmit
channels, transceiver mode
and modulation settings.
Tip: It is important to note
that data rates in excess
of 19.2kbps cannot be
achieved in LP mode due
to bandwidth limitations.
