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

the
modems

4. 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
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
and
de la gamme ARM : ARM-SE, ARM-D, ARM-DA, ARM-X,
