Control Options
Control options can be changed via the console using the print set routine (see print set mode). These control options can also be changed using TWICAL software, which is available on www.txwx.com. The first control option is daylight savings mode. When enabled this option will make the weather station automatically change the weather station time in keeping with daylight savings time as recognize in the United States. The second control option is wind speed scale. When turned on, the wind speed is in knots instead of the normal mile per hour or kilometer per hour when in metric scale. The third control option selects the manner in which the time is displayed.
To turn on the desired control options via the weather station display, refer to the table below, add up the values of the controls that should be turned on and enter that value into the weather instrument via the print set function (see page 12). The default value is 224. For example if you wanted AM PM turned on and instant wind speed output turned on you would add 32+128 which equals 192. Enter 192 into the weather instrument via the print set function.
