1. DESCRIPTION
MCF-LW06420 is able to read 2 analog inputs 4-20mA and 2 analog inputs 0-10V with a resolution of 12 bit.
The inputs have an insulation of 1000Vdc with respect to the power supply, and are protected against
polarity inversion.
2. CONNECTION OF THE DEVICE
Make the connections as follows:
2.1 Power supply:
➢red wire: positive power supply (range 10-36Vdc)
➢black wire: negative power supply
Power can also be supplied by USB.

3. LORAWAN™ACTIVATION
The device supports the following activations on a LoRaWAN ™ network:
NONE: sensor not activated
OTAA: needs settings of appkey and appEUI
OTAA MCF88: Over the air activation according to mcf88 specifications
ABP: needs settings of NwkSkey, AppSkey, DevAddr
The device exits factory activated with NONE mode. The devEUI of the device is shown on the product
label. MCF-LW06420 is a Class C LoRaWAN ™ device.

4. DEVICE CONFIGURATION
The activation parameters and the device settings can be read and modified via USB using the appropriate
"Lora PC" desktop application:
5. INSTALLATION
The magnetic antenna must be positioned on a metal body. It should preferably be vertical and at least 30
cm away from other metal bodies.
The installation must take place in a place where the LoRaWAN ™ signal coverage is good (SF=7 optimal,
SF=12 weak).
