2 x 3V CR2450 button battery power supply
Detectable voltage value and dry contact status
Simple operation and setting
4.Set up Instruction
4.1 Power on and Turn on / off
(1) Power on (insert batteries): open the battery cover (users may need a flat blade screwdriver to
open); insert batteries and close the battery cover.
(2) Turn on. If the device had never joined in any network or at factory setting mode, after powering
on, the device is at off mode by default setting. Press function key and release to turn on the device.
The green and red indicator will flash once to show that R311CA is turned on.
(3) Turn off. Press and hold function key for 5 seconds till the green indicator flashes quickly and
release. The green indicator will flash 20 times to show that R311CA is turned off.
(4) Remove batteries (power off) when R311CA is on. Wait till 10 seconds after the capacitance
discharging. Insert batteries again, the device will be setted to be on mode by default. There is no
need to press function key to turn on the device. The red and green indicators will both flash and
then light off.
Note:
1. The interval between turning on/off or powering off/on is suggested to be about 10 seconds to
avoid the interference of capacitor inductance and other energy storage components.
2. Do not press function key and insert batteries in the same time, otherwise, it will enter engineer
testing mode.
4.2 Join Into Lora Network
To join R311CA into LoRa network to communicate with LoRa gateway.
The network operation is as following:
(1) If R311CA had never joined any network or at factory setting mode, turn on the device; it will
search an available LoRa network to join. The green indicator will stay on for 5 seconds to show it
joins into the network, otherwise, the green indicator does not work.
(2) If R311CA had been joined into a LoRa network, remove and insert the batteries; the green
indicator will stay on for 5 seconds to show it joins into the network.
