OPERATION GUIDE
The MU-4 RS232C interface board, MU4-RS2IF is a development board for planning radio system with an RS232C
interface connection function that uses the embedded low power radio modem MU-4. Purchasing the board enables
you to begin evaluating communication with the MU-4 immediately.
The board with MU-4 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.

1.1.1 The MU4-RS2
In this operation guide, for the sake of convenience, the MU-4 RS232C interface board, MU4-RS2IF with the
embedded low power radio modem MU-4 mounted on it is referred to as the MU4-RS2. Before using the board,
mount the MU-4 on the MU4-RS2IF. When mounting the MU-4, 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-4 and the MU4-RS2IF from static electricity, earth yourself
before starting work.
•
Do not cause short circuits by dripping solder on the board.
Important
The development board does not include module MU-4. Please make sure to order it if needed.
It is not possible simply to replace communication using existing RS232C system equipment connected
with a cable, with MU4-RS2 wireless communication. The hardware and software must be designed
specifically for the MU-4.
