Before starting the product, read carefully the following recommendations:
For your safety, only use batteries recommend by ATIM (3V6 lithium).
Do not recharge batteries!
Do not use without antenna!
If the antenna is fixed outside on a pole, it must be linked to the ground. A surge protector must be placed on the cable, between
the antenna and the ARM radio modem.
Respect normes by using recommended cables and antennas in order to stay in the authorized powerful emission (depending on the
chosen channel: 5, 25 or 500mW).

INSTALLATION
2.1. Antenne
L'ARM-IO est fourni avec une petite antenne ¼ d'onde raccourcie, si vous souhaitez de meilleures performances vous pouvez utiliser
l'une de ces antennes:
✔ ANT868-12FSC (Antenne ½ onde): cette antenne peut être directement montée sur l'ARM-IO.
✔ ANT868-12S-L (Antenne ½ onde): Elle ne nécessite pas de plan de sol métallique pour fonctionner correctement et peut
s'installer directement sur un support en polyester d'un véhicule ou au-dessus d'un coffret en PVC.

Pour des résultats optimaux, Il est recommandé d'installer les 2 antennes à vue (sans obstruction entre la ligne de vue des
antennes) et de les placer aussi haut que possible (voir schéma).
2.2. Modes de communications
L’ARM-IO-LP-PT100 can work in 3
modes :
- Mirror mode
- Modbus slave
- Sensor mode (datalogging)
The mirror mode allows the contacts or analogical
transmission to a distant radio module, which can be
an ARM-D or an ARM-X and which can centralize the
values from several distant ARM-IOD-LP.
See the manual for functioning
choice.

In modbus slave mode, all
configuration
registers
are
accessible. Available functions:
-
Reading logical input
Reading/writing memorized input
Reading power supply voltage
Reading RSSI value
Reading/writing counter rising and
downing front (see manual )
- Reading analogical input
- Reading temperature
The ARM-IO are equipped with a
performing
sleep
mode
(configuration only with modbus
commands, see the manual).
The modbus mode is currently used with a master
modbus automaton or with a supervisor connected to
an ARM-IOS or an ARM-SE.
The sensor mode works with a master ARM-SE radio
modem, which automatically bring back information
in a cyclic way (datalogging). Data are then searchable
in modbus.
You can use all the ARM-IO with other radio modems
from the ARM range: ARM-SE, ARM-D, ARM-DA,
ARM-X, etc.
In mirror mode, the radio frame is
secured with addressing (last octet
of the serial number) and with
error control. By default the ARMIO is configured in slave mirror
mode. After configuration, and
after the first power-up, the
modems will automatically pair
each other.

CONFIGURATION IN MODBUS MODE
To erase the modem configuration:
– Disconnect the battery
– Discharge the modem residual voltage in bypassing the + and the - of the battery connector
– put the STRAP 1 (ON) and the STRAP 2 (ON)
– Put back the battery
– The LED is flashing rapidly
– Disconnect the battery
For initializing the modem (frequency selection and modem address):
– Disconnect the battery
– Discharge the modem residual voltage in bypassing the + and the - of the battery connector
– Remove the STRAP 2 (OFF)
– Put the STRAP 1 (ON)
– Put back the battery
– The LED is flashing: 1s ON and 1s OFF during 35s.
– If the modem receives a modbus frame on a frequency from its frequency table (radio frequency usable: channel 1; 3; 5; 7; 9; D; F;
see board 2.3), it records the selected frequency and the sent address. If there is no answer to the request, the LED is flashing:
200ms ON, 2s OFF.
– After 35s, the modem takes its default configuration and the LED is flashing: 200ms ON and 5s OFF
Default configuration:
– Radio channel 1 frequency
– Modbus address: last octet of the serial number
ARM-SE modem configuration with webpage:
–Select in the RADIO tab: « radio baud rate »: 9600bps
– Select in the SETUP tab: « Wake up sleeping slave »
ARM-SE modem configuration with AT commands:
– Register S04 hexadecimal value: 20
– Register S09 hexadecimal value: 12
– Register S36 hexadecimal value: AF
– Register S37 hexadecimal value: 00
5.
MIRROR MODE CONFIGURATION
To erase the modem configuration:
For initializing the modem (frequency and modem address selection):
– Disconnect the battery
– Discharge the modem residual voltage in bypassing the + and the - of the battery connector
– put the STRAP 1 (ON) and the STRAP 2 (ON)
– Link the logical input INP1 to the ground according to the desired cycle time:
- INP1 non connected : 1mn cycle time
- INP1 connected to the ground: 15mn cycle time
– Put back the battery
– La LED is flashing rapidly: 200ms ON 200ms OFF
– The modem is initialized in master mirror mode with the default address corresponding to the last octet to the MAC address
– Disconnect the battery
– Discharge the modem residual voltage in bypassing the + and the - of the battery connector
– Configure the slave ARM-D modem or the slave ARM-X mirror mode modem, local address=ARM-IO-LP modem address
Destination address=ARM-IO-LP address
– Remove the STRAP 2 (OFF)
– Put back the battery
– The ARM-IO-LP will search automatically the slave modem. The LED is lighting from the emission of a radio frame, or from the
reception of an answer to its question on a channel.
