OPERATION GUIDE
The MU-1 RS232C interface kit MU1-RIK is a development kit for planning radio system with an RS232C interface
connection function that uses the embedded low power radio modem MU-1. Purchasing the kit enables you to begin
evaluating communication with the MU-1 immediately.
The on-board MU-1 can be controlled using simple dedicated commands, so that the developer can concentrate on
designing the protocols for transmitting and receiving data, without needing to be aware of control of the radio
component. Since the control program created by the user accesses the host COM port, users can apply their fund
of knowledge of RS232C technology.
The MU1-RIK can be used with a variety of operating systems (Windows 98, Me, 2000, XP).
1.1.1 The MU1-RS2
In this operation guide, for the sake of convenience, the MU-1 RS232C interface board MU1-RS2IF with the
embedded low power radio modem MU-1 mounted on it is referred to as the MU1-RS2. Before using the kit, mount
the MU-1 on the MU1-RS2IF. When mounting the MU-1, observe the following cautions, and carry out the soldering
carefully.
Cautions for soldering
• To prevent damage to the connectors, solder the joints quickly.
• Avoid connection defects.
• In order to prevent damage to the MU-1 and the MU1-RS2IF from static electricity, earth yourself
before starting work.
• Do not cause short circuits by dripping solder on the board.
)Important
It is not possible simply to replace communication using existing RS232C system equipment connected
with a cable, with MU1-RS2 wireless communication. The hardware and software must be designed
specifically for the MU-1.

OPERATION GUIDE
1.1.2 Explanation of terminology
The meaning of the terminology used in this Operation Guide is as follows.
1. The “setup disk” is the CD-ROM that comes with each MU-1 series kit, that contains the setup program,
Operation Guide and so on.
2. The “Evaluation Program”is a program for evaluation of the MU-1 series of products, called the MU-1
Evaluation Software Program MU1-ESP. After installation it is found inside the “Circuit Design” folder that
appears on the desktop of your PC.
1.1.3 Features
The kit uses the MU-1 that has obtained the CE mark.
Circuit diagrams for making user systems are publicly available.
Compact size (47 mm × 71 mm × 18 mm) fits in a small housing.
Features of the MU-1 evaluation program;
1. You can issue all commands for controlling the MU1-RS2.
2. There is a test program for checking the communication performance of the MU1-RS2.
3. There is an air monitor function for checking the status of radio waves in the field.
1.1.4 Applications
Serial data transmission
Energy monitoring, data monitoring devices, handy terminals, barcode readers
Telecontrol
Remote control for construction machinery, display devices, motor control, lifters
Remote control of FA equipment
Telemetry
Water level monitors for rivers and dams, temperature and humidity gauges, rain gauges, pressure gauges,
voltmeters, ampere meters
Systems used with MU1-RIK must meet the following conditions.
1. OS: Windows XP, Windows 2000, Windows Me, or Windows 98
2. Web browser: Internet Explorer 5.01 or higher
3. Hard disk capacity: 30 MB or more
4. Memory: 60 MB or more

RS232C connector (D-Sub 9-pin socket):
A D-Sub 9-pin socket for RS232C. Connect the RS232C straight cable provided.
You can also supply power from the RS232C connector pin No.1. For details, refer to the circuit diagram.
Power terminal and power switch:
The connector for the power supply. Connect a 9 V battery with the battery snap provided.
* If you connect to a power supply other than a 9 V dry battery, ensure that it is DC +3.2 V to DC +12 V. Be sure to
connect the power supply with the correct polarity.
Power LED: The LED comes on when the power switch is turned on.
Initialize switch: Resets the MU-1 mounted on the MU1-RS2 to the factory default settings.
Initialize the unit if communication with the MU-1 is not possible or if you are uncertain of the internal settings.
λ/4 Lead antenna: A λ/4 long lead antenna (ANT-LEA-01).
MU-1: A specific low power serial data transmission modem.
TX-LED: On when data is transmitted.
RX-LED: On when data is received.
