GM1212 Geist Watchdog Wi Instruction Manual
Safety Precautions
The Watchdog Wi Range extender is not a grounded device. External circuits (USB port
and power supply) are required to be double or reinforced insulated (Class II circuits).
The power to the Watchdog Wi Range extender must be supplied from a limited energy
circuit: 5VDC with a maximum available current of 10A or a Class 2 circuit.
Communications Objects
The Watchdog Wi can communicate via Modbus, BACnet, and SNMP. Each sensor has
its own Modbus Registers, BACnet Instances, and SNMP Object Identifiers (OIDs). This
table is provided for reference. Please note that the values presented in Reading #2 and
Reading #3 will vary depending on the type of sensor with which you are working. The
table presents specific communications objects for sensors 1 - 20. Looking at the table,
we have bolded the numerical changes to help you see there is a pattern to the Register,
Instance, and OID assignments and a direct connection between the sensor number and
the communications objects. A formula at the end of the table will help you calculate
Modbus Registers, BACnet Instances, and SNMP OIDs for sensors past the number of
sensors that are detailed in this table. Communications objects for sensors 1 through 20
have been diagrammed in the following table:
