2. INSTALLATION
It is necessary to open the case to get to the mini-USB port to
be able to configure the modem and to get to the terminal
block.
To do that, you have to insert the screwdriver into the slot
and tilt it downwards to lift the internal locking tab (cf.
photo). Then pull at the back of the casing to separate both
parts.
For optimal results, it is recommended to install the case
without environmental obstruction and to place it as high as
possible. For information, the antenna is integrated into the
case.
The case can be fixed on a flat wall or a tube following the
type of installation.
The orange button allows you to send a message to validate
the installation.
You can connect up to two digital inputs in counting mode or in alert
mode by level detection. The signal must be realized by one contact or a
push-pull output that doesn’t exceed 5V in high level. The ‘Break of cable
' input is for a fraud detection if the modem is taken away, this
information is periodically sent during the remote reading of the meter.
Type de câble à utiliser: maximum length 1 meter and recommended diameter 0,9mm, the thread on 9mm.
In the few seconds following the implementation of the power supply, a first radio transmission is made (visible by a
brief blue blinking of the LED) to allow you to verify functioning of the modem.

3. CONFIGURATION
Download and install the configuration software
‘’setupACW.exe‘’ at this address :
http://www.atim.com/produit/atim-cloud-wireless-acw/
Connect the modem to the computer via the USB cable and
launch the software.
When you connect the modem, the software window
changes to allow you to reach the central features.
Automatically, the current configuration of the connected
modem is showed. You can then see this window.
The window is divided into different parts.
1 : Functioning mode: Two functioning modes are
available, slave and master.
In Slave mode it is your distant modem that is going to send a request to your ACW-DI.
In Master mode, the ACW-DI will send periodically (from 10min to 24h) or by the inputs change of state.
2 : Configuration des entrées : The ACW_DI module has 2 configurable inputs either for the detection of change
of state or to meter mode. Every input can be activated or not.
When the digital input is configured, this one detects a change of state on the chosen front.
Rising front
Downward front
Downward and Rising front
The signal must be realized by one contact (bounces are eliminated by soft) or a push-pull output where the
high level does not exceed 5V
When the input is configured in meter mode, this one counts the pulses that appear. The meter is incremented
on the rising front of the signal. The signal must be realized by one contact without bounce or a push-pull
output where the high level does not exceed 5V.
3 : Radio settings :
The radio channel has to be the same between your various equipment’s that want to communicate
together.
The modems address must corresponds to the address of your ACW-DI, every modem has to have a
different address.
The distant address is the address of the device with which you want to communicate.
4 : Statement period of the meter(s) : This menu allows you to configure the time between 2 sending’s of data.
This period is between 10min and 23h50min with a step of 10min. It is also the period in which will be made the
break of cable detection.
If you omit to define one the statement period fields. When you will click on Write a Invalide will appear next to
this one and a message will inform you about it and will indicate to you which field is at fault.
5 : Configuration : When you have finished, just click on Write for the validation. After a few seconds a message
appears next to this one to inform you if the modem has been updated or has failed. Note : It is in this phase that
the modem is updated with the hour on your PC.
6 : Default : Allows you to reset previous values of the meters. After erasing the protected values, you have to
configure the ACW-DI module again.
Once the configuration is finished, do not leave the module connected by USB. This way of functioning
uses a lot of energy. When you remove the USB connection without disconnecting the power supply
the module returns automatically to normal functioning and a first radio transmission is made in 60s.
