Page 19: Parameters Configuration
Parameters Configuration Parameters Configuration Before using the PULSE915-LRW terminal, we need to configure some parameters, such as initial index, pulse constant, RTC real-time clock, pulse type (single or double pulse), sensor type (hall or reed switch) and other LoRaWAN information. The configuration mode supports wired wireless. -
Page 20: Entering Configuration Mode
PULSE915-LRW_User_Manual 5.1.3 Entering Configuration Mode PULSE915-LRW terminal can be activated by magnet to enter configuration mode. Both the wired configuration mode and wireless configuration mode need to be activated before parameters configured. The reed switch inside the product is triggered by the magnet to put the product into the configuration mode, and then the configuration command must be sent within 30 seconds. -
