2 Application
The Weather Display LED is a modern data-processing measuring and display device for the
display of to four measured values. Depending on the version it is also used for serial and analog
output of the measured data to further processing systems.
The device operates in conjunction with a weather station (e.g. data logger), which supplies a serial
data protocol. Optionally the Weather Display LED also acquires analog data (see Device versions)
from direct-connection sensors with analog outputs.
Configuration is carried out either at the factory according to the data protocol of Thies products
(weather station, data logger etc.) or on the basis of a data protocol as per customer specification.
The Weather Display LED is characterised by its high reliability and flexibility as well as optimum
display of the weather parameters.
Red light-emitting diodes (LEDs), which are easily to read under a wide range of lighting conditions
and distances, are used for display. The brightness is adjustable. Two brightness levels can be
stored using an extended dimming function. This allows individual settings for daytime and night-
time brightness to be called up quickly.

4 Mode of Operation
4.1 Calculation of sliding mean and extreme values:
To process the sliding measured values two ring buffers with a depth of 60 single values are
available for each measured value. With processing of the measured values every second this
results in a 1-minute sliding extreme and mean value. With the selection of times > 1min, the
measured values are processed to produce an integral extreme and mean value prior to sliding
processing.

averaging)

10 min 10 60
1 h 60 60
24h 1440 60
5 - 30 021503/10/07

The ring buffers are initialised whenever the Weather Display is started up. The first valid measured
value is written to the ring buffers so that a measured value appears in the display at once. A
regular extreme or mean value is then available after the time selected.
The times selected are not synchronised to the clock time. They indicate the period of time in the
past.
Available time settings:
Parameter Time
Extreme value 1min 10min 30min 1h 2h 6h 12h 24h
Mean value no 1min 10min 30min 1h 2h 6h 12h 24h
4.2 Calculation of Sums
The menu sum „Su“ facilitates the configuring of a display line into a sum channel.
The input value, related to the display line, must be a sum value, too.
The addend for the sum to be indicated is calculated from the difference between the current input
value and the „old“ input value. The measuring range of the input values is acquired automatically
in increments, so that the sum overflow of the input value is identified and respectively processed.
Sum ranges:
Parameter Sum
Value 10,0 20,0 25,0 50,0 1000,0
The accepted increment within a second-by-second-query is between 0.1 and 1.1. Values of
outside the range are not accepted, and lead, after 2 sec, to a new vasic value for the following
totals formation
The totals formation, once started (Power On), and the indicated sum value, are reset exclusively
by the internal clock (RTC) at 00:00, or by a RESET.
4.3 Elevation Input to the Air Pressure (Function only with instrument
9.2750.1x.901)
The wind display indicates the absolute pressure (P) or the air pressure (QNH), reduced to the sea
level. The absolute pressure is the standard factory setting, in case no other written arrangement
has been made.
For the setting of the display of the air pressure (QNH), reduced to sea level, the baro station height
(above sea level) must be entered.
The range of the baro station height input is 0.. 3000 m. The input is done by the front side keys,
and is indicated in the display line „Pressure“.
For description of the station height input please refer to operating examples point 6 (chapter 8).
6 - 30 021503/10/07

4.4 Acquisition of measured values
The acquisition of measured values is carried out via the serial interface (RS422) or optionally the
analog inputs.
The parameters required are filtered out of the data protocol received or the analog values and
assigned to the relevant LED displays.
Configuration of the Weather Display LED is carried out at the factory. Any ASCII data protocols
can be interpreted.

5 Recommendation for Selection of Site
The device is designed for indoor installation. When used outdoors, an additional external housing
including the appropriate type of protection is required.
Note
When selecting the installation site please take note of the operating temperature
range.
6 Installation
Caution
The device should only be installed and connected by qualified
technicians. The general engineering regulations and
provisions and standards applicable must be observed.
6.1 Mechanical installation:
The display is designed for control panel installation. The necessary opening in the control panel
must measure 138 x 138 mm. The scope of supply includes two fixing brackets. After the device
has been inserted in the control panel, the fixing brackets are slid into the housing at the rear and
screwed into place.

Information for RS422:
Faults on long cables may affect serial transmission may affect serial transmission, with the serial
interface possibly being destroyed by over voltages. We therefore recommend:
• The transmission line should be shielded. The shield must be connected to a central earth
potential.
• With cable connections longer than 100 m twisted pairs should be used for the signal lines +RX/-
RX and +TX/-TX.
• The ground pins (GND) should also be connected in addition to the twisted signal lines. If major
differences in potential between the transmitter and receiver result in high compensating
currents, isolating interface adapters have to be used.
• The cable must always be terminated with its surge impedance (100 Ωto 600 Ωdepending on
cable). With more than one Weather Display LED (slaves) the resistor must be located at the
receiver furthest from the transmitter.
• The integrated termination resistor (RT=200Ω) has to be activated with the use of a jumper (X7)
at the receiver (slaves)(see Fig. 3.).

7 Data Output Protocol
The output protocol contains all four display parameters. They are output in the display sequence 1
... 4 and in the display format.
e.g. Weather Display protocol: (STX)xxx.x xxx.x xxx.x xxxxx*HL(CR)(ETX)
- ' ' is used as a separator
- Erroneous parameters are replaced by "???.."
- Missing parameters are replaced by "---.."
- Measured values are output with a leading ' ' e.g. ' ' 0.1
Abbreviations:
' ' = blank character
"*" = identifier for checksum
"H" = checksum high
"L" = checksum low
<STX> = start of text
<CR> = carriage return
<LF> = line feed
The checksum is generated by the XOR function from the characters between <STX> and "*" 2…9
(starting with Hex00). The 8-bit checksum is then split into two ASCII characters (high and low
nibble) with a value range from 0...F (Hex).
Note for COM1 Input:
The COM1 interface can be configured with any protocol. See Section 4.2.

8 Operation
The display is operated using the buttons on the front (s. Fig. 4). Whenever a button is pressed,
this is acknowledged by an acoustic signal.
The Table of operating functions summarises the operations possible. The MODE button is used
to navigate through the 3 operator control levels (Mode 0-2). The areas marked in white in the table
symbolise general operating functions of the display such as dimming, baud rate etc. The grey
areas symbolise operating functions that specifically relate to a parameter (measured value)
(display of min./max value etc.).

The button "MODE" can be used to move to the next level. Indicated by the flashing MIN/MAX
LEDs in each level.
The buttons button "▲"(UP) and button "▼" (DOWN) can be used here to display the Mom,
