Address Mode

The SureCross wireless devices may use one of two types of addressing modes: rotary dial addressing or extended addressing. In
rotary dial address mode, the left rotary dial establishes the network ID and the right rotary dial sets the device ID. The wireless network
is restricted to a maximum of 16 devices.
Extended address mode uses a security code to "bind" Nodes to a specific Gateway. Bound Nodes can only send and receive informa-
tion from the Gateway to which they are bound. In extended address mode, wireless networks may contain up to 48 radio devices. For
more information on extended address mode, refer to the SureCross™ Wireless I/O Network product manual.
The device ships in rotary dial address mode by default, with the DIP switch in the OFF position. To use extended address mode, change
the DIP switch to the ON position.

Baseline Threshold/Filter (M-GAGE)

Under normal conditions, the ambient magnetic field fluctuates. When the magnetic field readings drift below a baseline threshold setting,
the baseline or drift filter uses an algorithm to slowly match the radio device’s baseline to the ambient magnetic field.

Discrete Input Type

Select the discrete input type: sourcing (PNP) or sinking (NPN).

Threshold and Hysteresis (M-GAGE)

Threshold and hysteresis work together to establish the ON and OFF points for analog inputs. Setting a threshold establishes an ON
point. Hysteresis defines how far below the threshold the analog input is required to be before the input is considered OFF. A typical
hysteresis value is 10% to 20% of the unit’s range.
The M-GAGE Node’s threshold and hysteresis ranges are 0 to 65,535. The factory default threshold setting is 100 and default hysteresis
is 30 (the sensor detects an OFF condition at threshold minus hysteresis, or 100 - 30 = 70). With the default settings, once the magnetic
field reading is above 100, an ON or “1” is stored in the lowest significant bit (LSB) in the Modbus register. When the M-GAGE reading
drops below the OFF point (threshold minus hysteresis), the LSB of the Modbus register is set to “0.” To determine your threshold, take
M-GAGE readings of the test objects at the distance they are likely to be from the sensor. For example, if a car reads 100, a bicycle 15,
and a truck reads 200, setting the threshold to 150 will detect only trucks of a specific size. Magnetic field fluctuations vary based on the
amount of ferrous metal present and the distance from the sensor.
