The Z sensors has three different ports: Port 0, Port 1, and Port 2.
Port zero is an internal sensor that is built into the Z sensor. It is not NIST-certified and will not be visible outside of the device. Port 0 also allows the Z sensor to monitor up to 3 areas of an asset with just one unit, using both the internal port and the two external ports (Ports 1 and 2).
Ports 1 and 2 are NIST-certified, and can be connected to other sensors.
Note: Temperature may vary slightly compared to external readings due to Port 0 being encased inside the device.
