NNW

In order for these cardinal points to line up to correct North, you must initialize the

TEMP08 first by manually (physically) setting the Wind vane to point to North and

then use the NOR command to save that direction in memory.

Wind speed is shown as an average of the speed over the previous polling

interval. The Gust speed is the maximum speed in any 1-minute period of any

polling interval. If the polling interval is set to one minute via the SPT command,

then the gust speed will not be displayed.

Rain is displayed in Inches and assumes that your rain gauge counter is

calibrated to count once for every 0.01 inch of rain. Rainfall is measured from

the time of the last reset (RST command) of the rain gauge.

General-purpose counters are used for many things. Both A and B counters of

the connected DS2423 sensor are displayed. Counts are based on the number

of counts stored in the DS2423 since the last reset (RST command) of the

counter.

The 1WIO status displays the current input status of connected DS2408’s

configured via the TYP command to be of the “I” type.

5.4. Missing Sensor Display

TEMP08 continuously polls for the presence of all sensors that have been INI’d

(initialized), in other words, for sensors that are known to TEMP08. If any of the

sensors are detected as missing, the following display will result:

>MON 09:52:34

Missing Sensor #04 [9900080049199310]

When the sensor is re-connected, the display will look like this:

>MON 09:57:01

Restored Sensor #04 [9900080049199310]

Polling of sensors is done sequentially and very fast (milliseconds per sensor).

The more sensors that are equipped, however, the more time it will take for

TEMP08 to recognize a missing or re-added sensor.

It is normal to experience missing sensors from time to time due to noise on the

1-Wire bus. If any particular sensor shows very high disconnect readings, you

might want to check the wiring for that particular sensor.
