5) Sensor connections to Node:
A. Strip the cable sleeve back by 8mm.
B. The 5 wires from the cable are 12V_Out, GND, A, B and GND. Please refer to the sensor datasheet to identify
the purpose of the stripped wires.
C. Untighten the gland cover, insert cable through the gland, then connect the 5 wires accordingly.
D. Once the wires are connected, please tighten the gland cover firmly to ensure its IP rating on that channel.
Notice 1: The cable gland diameter of the RS-485 Interface Node is 8mm.
Notice 2: All the 5 wires must be connected, to minimise electrical interference and possible loss of precision.
Notice 3: Within any electrically noisy environment, nodes with sensors must be >= 0.3m away from the source of
the noise.
6) Power On: once all the RS-485 sensors are connected, turn the switch on. Now you should be able to see 3 LEDs
flashing 3 times, that means the node is on. Then switch off the node to save power if the gateway is off;
7) Tighten the 4 Cap-Hex-Head screws of the lid to secure the enclosure IP rating;
8) To validate the sensor data, please visit WISENMESHNET

5.3Mounting Options
RS-485 Interface Node can be deployed with various methods. However, the priciple is to make sure it is firmly
attached to the installation surface.
6. General Maintenance and Notification
1) Once RS-485 Node is installed in the field, please minimise any man-made disturbance so that data
quality can be maintained;
2) Radio communication will be impaired if the antenna is covered by metal or very moist soil material;
3) Due to the discharge characteristics of the recommended battery, a battery replacement should be carried out
when a node reported voltage reaches 2.7V, at which point you have approximately 3 weeks to change the
battery;
4) Our product will use all the possible capacity in a battery down to a stop (minimum) voltage, which has been
specified in the Features table. When this occurs, our WISENMESHNET protocol will send you a warning then it
