1. Introduction
LoRa devices SC15L, SC15L241 and access point SC15L APS are ideal for machine
monitoring and sending sensor data using LoRa wireless technology over long range.
SC15L is a LoRa device which connects transparently to the SC15L APS access
point. SC15L241M sends IO data or field Modbus slave devices data to the SC15L
APS, which gives output in Modbus RTU interface for monitoring. SC15L APS is used
in 2 modes viz. Transparent and Modbus RTU Slave depending on application
requirement.
GW IoT EL and GW IoT G8L are Ethernet and Cellular IoT LoRa gateways
respectively which are used for sending data received from SC15L241M to the Cloud.
Hundreds of sensors can be clustered together on single network and data can be
aggregated at central monitoring system. This system is used in industrial applications
for reading analog and digital inputs.
2. Features
➢
SC15L241 supports 2 Analog Inputs (4-20mA), 4 Digital Inputs (Potential Free)
and 1 Digital Outputs (Potential free ).
➢
SC15L supports RS485 port two wires and RS232 interface.
➢
Robust design with DIN rail mounting and wall mounting enclosure
➢
Industrial Screw type Power Terminal block for 12V DC operation
➢
Communication:
•
Frequency Band: 867 MHz
•
Outdoor/RF Line-of-Sight Range: 3.5km
•
Transmit Power: Up to 20dBm (100mW)
•
Receiver Sensitivity: -140dBm at bits: 8
➢
Antenna connector: SMA female type, the characteristic impedance of 50 ohms
System will need this gateway to be paired with any one of receiver LoRa
gateways or routers.
3. Operation
3.1
Transparent mode:
In this mode SC15L device will connect to a specific SC15LAPS device, both devices
will be in same transparent mode. SC15L/SC15LAPS device will transmit serial data
to other connected device transparently SC15L APS will broadcast the serial data
received on its serial port to all connected SC15L devices in the network and all
SC15L devices will transmit their serial data to access point (SC15LAPS).
