ATIM_ACW-DINDIO_868_UG_EN_V1.3
Set up
a.
Positioning
This version was designed for installation in an electrical box made of PVC or metal. If the cabinet is
made of insulating material (PVC, ABS, fiberglass), it is possible to simply use a small whip-wave
antenna: Ref ATIM ANT868-12FSC. This antenna must be firmly screwed on the SMA connector and
positioned vertically, preferably upwards.
➔
In the case of a metal box, it is imperative to deport the antenna to the outside to have good
results in radio (avoid the Faraday cage!)
For best results, it is advisable to move the antenna up and clear of any metal obstacle within a radius
of 1 meter if possible.
b.
Modem connection
Terminals:
Antenna (SMA):
Before powering the product, a 50Ω / 868MHz antenna must be connected, either
directly to the SMA connector or via a 50Ω cable in case of antenna offset.
Alimentation (Lower terminal):
The ACW-DIO module must be powered with a continuous power supply between 10V
and 30V.
OUT (Lower terminal)
:
The logic output is MOSFET current source (N channel), 10-30Vdc. The maximum
charging current is 0.2A.
IN1/IN2 (Upper terminal):
You can connect up to two inputs in 10-30Vdc positive logic. The filter of the input is 250
ms. The maximum recommended cable length and 1 meter.
USB:
The USB connector is used to configure the ACW via a PC and a USB cable.
➔
The configuration must be done with the device powered by 10 / 30Vdc.
