The modbus mode is frequently used with a master
modbus automaton or with a supervisor connected to an
ARM-IOS or an ARM-SE.
The sensor mode works with master ARM-SE radio
modem, which can repatriate automatically and cyclically
the information (datalogging). Data are then searchable
in mdbus.
Vous pouvez utiliser les ARM-IO avec les autres modems
de la gamme ARM : ARM-SE, ARM-D, ARM-DA, ARM-X,
etc.

CONFIGURATION IN MODBUS MODE
The modem configuration can be made in the manufactory.
For erasing the modem configuration:
– Disconnect the battery
– Run down the remaining voltage in shorting circuit the + and the - of the battery connector
ARM-IO
are
provided
with
a
performing sleep mode (configuration
only with modbus commands. See the
use manual).
In mirror mode, the radio frame is
secured with addressing (last octet
of the serial number) and with an
error controller. By default the
ARM-IO is configured in slave mirror
mode. After configuration and
switch on, the modems will
automatically pair each other.
