Embedded low power radio modem
MU-1
The MU-1 is a serial data communications modem
designed to offer the reliability, shock resistance,
vibration resistance and high quality required for use
in industrial applications. The MU-1 uses the UART
serial interface to interface with the host system,
while data input/output is performed with simple
commands.

Circuit Design, Inc.has updated the MU-1 low
power radio modem launched last year with new relay
and communication margin measurement functions.

New Relay Function
|
|
With the new relay function you can now achieve
long distance communication (1 leg about 600 m)
using a maximum of 10 relay stations, with 10 mW.
This enables a broader range of industrial applications
such as data acquisition over wide areas and control
of equipment placed in remote locations.
The new relay function is achieved by issuing
dedicated commands from the source station.
Not only can you transmit and receive system data
over a relay, you can also remotely set system
channels from the source station.

Communication margin measurement function
|
|
In addition, we have added a new command for
measuring the communication margin.
You can remotely check the field strength of target
stations in remote locations with commands from the
source station. Also we have provided a convenient
command for measuring packet success rate. Since
you can easily check the status of each station, it is
possible to devise a design that achieves optimum
performance and you can locate the equipment
optimally for the radio wave environment to ensure
more stable, reliable communication.

MU-1 Development kits
|
|
In order to support a variety of interfaces, we offer
an RS232C interface kit, USB interface kit, and LAN
interface kit, which enable you to begin evaluating
communication with the MU-1 immediately.
