INITIAL STARTUP
Vega SI-21 pulse counter is constantly on but can operate in a special "Storage" mode,
designed for storage and transportation. The device does not regularly transmit data to the
network in this mode. Before use switch the counter from the «Storage» mode.
Vega SI-21 supports two activation methods in the LoRaWAN network - ABP and OTAA.
Select one of the methods using the «Vega LoRaWAN Configurator» application (see part 4).
1. ABP. After pressing the start button, the device immediately starts working in the
"Active" mode.
2. OTAA. After pressing the start button, the device makes three attempts to connect to
the network within the set frequency plan. After the activation in the LoRaWAN network is
confirmed, the device sends a signal (LED flashing for 3 seconds) and switches to the "Active"
mode. If all attempts fail, the counter will continue to accumulate data and will attempt to
connect to the network every 6 hours.
Hold the start button pressed (min. 5 seconds) to switch the device from the "Active"
mode back to the "Storage" mode.
When switching to the "Storage" mode, all readings from the pulse inputs
accumulated in the device memory are reset
