XII. THE ULTIMETER 100 SERIAL PORT
The
ULTIMETER
100 provides a unique 7-mode serial port to facilitate
computer data logging and remote data reporting via telephone, modem,
or RF link. Each of the four modes can be accessed by pressing and
holding a combination of two keys, or by command into the serial port.
The following is a brief description, to provide an idea of the capabilities
of each mode. The serial port is located in the Junction Box (receptacle
"
i/o
") and also the right-side receptacle of the keyboard/display.
Complete details are available to programmers upon request or at
www.peetbros.com.
WEATHERTEXT OUTPUT MODE
In WeatherText Output Mode, the instrument puts out one human-
readable (text) Weather Report each minute. The serial text output
is viewed on the monitor of a PC using terminal software such as
HyperTerminal (located on your WIndows PC at
Start/Programs/Accessories/Communications/HyperTerminal), or
using
WeatherText
™
Tools
software from Peet Bros. The text
output may be "captured" and saved as a .txt file for later viewing or
printout. Communications settings are 2400/8/N/1 (contact Peet
Bros. Tech Support for further assistance). Each "WeatherText
Report" includes all current values, plus the highest wind speed
over the past minute with the associated wind direction, the average
wind speed over the last minute, today's and long-term rainfall,
today's highs and lows, and current time and date. Key Combo:
Press and hold
and
for 3 seconds to enter this mode. In
addition, each time this key combo is pressed, a comprehensive
"Complete History Report" is output (contains highs and lows for the
previous 7 days plus long-term). Following is a sample
