PULSE915-LRW_User_Manual 1 Introduction This document describes the technical parameters and key functions which are connected with customers’ applications, and it can help customers quickly understand the data format, wiring definitions, as well as other related information of PULSE915-LRW. Associated with configuration user manual, customers can use the terminal to any pulse emitting device (water, gas, electricity, etc.) easily. 2 Product Concept 2.
PULSE915-LRW_User_Manual Lifetime depends from the device location and reporting interval. 2.3 Specifications The following table describes the specifications of PULSE915-LRW Table 2- 1 Specifications of PULSE915-LRW Specifications Description Dimensions (L*W*H): 50 mm x 45.5±0.
PULSE915-LRW_User_Manual pulse signal input port supports single pulse and double pulse signal input. It supports both active and passive sensors. The sampling pulse time is less than 5ms, which can meet the requirement of typical water, electricity and gas instrument pulse acquisition. 2.

PULSE915-LRW_User_Manual AT+I Query the current electronic index, the unit is m³ AT+I=xxxxx.xxx Set the initial index, such as the current value of meter. Max. value is 5 integers and 3 decimal, the unit is m³. For example, to set the initial index is 55.123, the command is as follows: AT+I=55.123 Set InitValue = xxxxx.xxx Error AT+P Query pulse constant PulseConst = xxx Error Set PulseConst = 1000 Error AT+T RTC real-time clock query RTC real-time = year.month.
PULSE915-LRW_User_Manual hexadecimal digits. Example: AT+DA =ABCDEF01 AT+VP Read pull-up resistor configuration of external Vcc and two pulse sampling ports Vcc = **(ON), Pull Up = **(OFF) AT+VP=”vcc state”,”Pull up state” Set pull-up resistor of external Vcc and two pulse sampling ports. ON is open OFF is close Example: AT+VP=ON, OFF Set Vcc = ON, Pull Up = OFF AT+NP Read pulse type, support signal and double type.
PULSE915-LRW_User_Manual AT+DR=band Set the frequency band. For example, set the band to AU915. The command is: AT+DR=AU915. +DR: XXXXXX AT+CH=NUM, chm-chn Set channel. The transmit channel of the module must be consistent with the receive channel of the gateway. For example, set the channel to 0-7.
PULSE915-LRW_User_Manual Each pulse of 1 liter of water produces 1 pulse, that is, 1 m3 of water meter will produce 1000 pulses, then the pulse constant should be 1000 (if the pulse constant is reset, the initial reading must be reset). Parameter configuration can be manually entered through the serial port debugging assistant, or can be carried out using the PC software provided by Friendcom. 5 Parameters Configuration 5.
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.
PULSE915-LRW_User_Manual 9s-15s >15s Reset Typically 12s No response Close magnet detecting function 60s When the product exits the configuration mode, basing on whether the user has sent a network access command (AT + JOIN) and whether the current mode is OTAA, it will automatically join the network if both are satisfied. The network access result can be verified by triggering whether the data report is successful.
