5. Operation Procedures
5.1．System Deployment Notifications
1) Location: The deployment location of a RS-485 Interface Node is usually determined by the required monitoring
or inspection location;
2) Before any RS-485 Interface Node is switched on, two tasks will need to be carried out:
A. Unlike the Tilt Node which has a MEMS tilt sensor embedded in the node, the RS-485 sensors chosen by the
customer must be connected to the RS-485 Interface Node;
B. A gateway must be deployed, powered on and proven to be working properly. Otherwise, the nodes will
need to be switched off, then switched on again after a gateway is switched on. So simply speaking, the rules
to follow to correctly deploy a WISENMESHNET system are:
1) Gateway first;
2) then nearby nodes with the RS-485 sensors connected;
3) then further nodes with the RS-485 sensors connected.
3) During deployment, the Serial Number, i.e., SN of a node and the orientation of the RS-485 sensors deployed
against their site references must be recorded;
4) The connections between a customer chosen RS-485 sensor and a Wisen RS-485 W Interface Node must strictly
follow the rules stated in this document;
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 RS-485 sensor is deployed onto a structure correctly, please
strictly follow the corresponding manufacturer sensor instructions.
