5.5. Discrete Option Commands
5.5.1. Once Per Minute Time Display (ETI)
Another option is to enable or disable the once-per-minute time display. The
command ETI on enables the display.
5.5.2. Temperature Display from DS2438 (ETE)
Another option is to enable or disable the temperature display resulting from the
on-chip temperature sensors present on DS2438 devices. If enabled, this
temperature will be included in the normal poll or TMP display. If disabled the
temperature display is suppressed. The command ETE on enables the display.
5.5.3. Display Wind from DS2450 (EWN)
If enabled (EWN on), the first connected DS2450 will be assumed to be a
Weather Station wind direction sensor and other DS2450’s will be displayed as
voltages. If disabled (EWN off), only voltages will be displayed from all
DS2450’s. The command EWN on will enable the display of wind direction.
With EWN set to on, the polled output (or TMP output) will look like this:
Wind Dirn[9F00000001087320]= NNW
With EWN set to off, the polled output will look like this:
Voltage #01[05300000CD2C1220]=02.60V 05.03V 1.38V 4.25V
5.5.4. Wind Direction Reverse (WDR)
This parameter is normally set to Off. Set this to On if you accidentally installed
the wind direction PCB upside down in your weather station OR if you want to
display wind direction as the FROM direction instead of the TO direction.
5.5.5. Set Poll Time (SPT)
This parameter determines the time between sensor readings. Set this
parameter to 00 to stop polling. Enter the time in decimal minutes from 00 to 99.
Leading zeros are required here!
5.5.6. Set Temperature Display (STD)
This parameter determines how temperature readings are displayed. Enter F for
Fahrenheit or C for Celsius.
