to follow to correctly deploy a WiSenMeshWAN® system are:
Gateway first, then nearby nodes, then further nodes.
4) During deployment, the Serial Number, i.e., SN of a node and the orientation of the Voltage sensors deployed
against their site references must be recorded;
5) All the node should have its antenna point upwards.
5.2．Deployment Procedures
1) Open the box: Take the node out of the package and open its lid;
2) Insert Battery: By default, a node does not contain a D-Cell battery. Therefore the battery needs to be inserted.
Notice : +ve and –ve orientation must be correct, otherwise, the internal circuit may be damaged, special
attention must be paid to avoid shorting the battery by the battery holder.
3) Antenna Installation: screw the antenna tightly onto the node;
4) Sensor Installation: To ensure a customer chosen Voltage sensor is deployed onto a structure correctly, please
strictly follow the corresponding manufacturer sensor instructions.
5) Sensor connections to Node:
A. Strip the cable sleeve back by 8mm.
B. The 3 wires from the cable are Vcc_Out, In1 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 3 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 Voltage Interface Node is 8mm.
Notice 2: All the 3 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) Sampling Range Selection:
“Vcc_Out Switch” is used to select the option of:
A. Sampling “Voltage Signal Output Range” from an external sensor;
B. Providing “Input Power Voltage” to an external sensor, e.g., for 6C01 type, “Vcc_Out Switch” of 2.5V
must be selected so that the EC-5 soil moisture sensor can be powered at 2.5V and also the node can
sample between 0 and 2.5V from the sensor.
Notice: For any other sensors, please check against the sensor specification before the setting is completed！
