Outdoor LoRa Data Logger

Connect to devices via DIs / DO (Digital Input / Digital Output) :
The OOT550 provides 2 DI ports and 1 DO port for connecting to those digital sensor/meter devices. To
connect the device, you have to identify the type of your device and properly connect and configure the
OOT550 so that it can get the correct readings from the connected devices.
The DI port supports either Pulse counter mode, or just a Dry contact. Since the OOT550 can not detect what
kind of device is connected to, not only hardware configuration (
CON4
) is required, but also software
configuration is mandatory.
