Texas Weather Instruments, Inc. 1 WRL Instruction Manual

WRL

Weather Report Logger

The WRL senses wind, temperature, humidity, barometric pressure, rainfall and time, then

outputs this data via a RS-232 interface to other devices. The WRL can be programmed

to output current weather, along with minimum and maximum conditions for the day. The

WRL keeps track of two different minimum and maximum values and up to 8000 lines of

data (depending on memory size) in its non-volatile memory clock. The WRL-10 has 2K of

memory and will retain approximately 30 lines of data. The WRL-32 has 32K of memory

and will retain approxomately 2000 lines of data. The WRL-128 has 128K of memory and

retains about 8000 lines of data. All functions of the WRL can be controlled through its RS-

232 interface.

Included with the standard WRL system is a wind direction and speed sensor, a pagoda

mounted temperature/humidity sensor, a rain collector and a pressure sensor installed in

the display console. Options include solar radiation, lightning and leaf wettness sensors.

Normal Operation

When in normal operation (no buttons depressed) the instrument displays current wind

direction and speed, cycles current time and date, cycles current indoor, outdoor

temperature. In addition, if selected, the optional solar radiation or aux temperature is

displayed when both the indoor and outdoor indicator lights are extinguished. The unit also

cycles current barometric pressure, current relative humidity, and cycles daily, monthly and

term cumulative rainfall. By utilizing the hold buttons associated with each display, the user

may select the most important readings to the user. During wind speeds in excess of 99

miles per hour a small light turns on between the digits of the wind speed display.

Trend indicators (arrows) are located to the right of the temperature, relative humidity, and

barometric pressure displays. If, for example, the current relative humidity is increasing

then the up trend arrow appears on. If there is no change in humidity, then the arrow would

not appear.

Installation

The standard WRL uses three sensors to gather weather data. The wind direction and

speed sensor, the temperature and humidity pagoda and the rain collector (see figure 1).

All are designed to mount to a television type mast (not provided). The cables from the

sensors go into a junction box, where they connect via RJ45’s to two multi-wire cables

(intermediates) that are routed into the building and attached to the console. All cables are

color-coded. The yellow wind sensor cable plugs into the yellow RJ45 connector in the

junction box. The yellow intermediate (wind) also plugs into a yellow RJ45 connector in the

junction box. Plug the temperature/humidity pagoda and the rain collector (both colored

blue) and the blue intermediate into the blue RJ45 connectors in the junction box. You may

place any blue cable into any blue RJ45 connector, the order does not matter.
