terminal; The BLACK wire i connected to a GROUND terminal; the GREEN wire (wind
direction ignal) i connected to the A7 terminal and the WHITE wire (wind peed
ignal) i connected to the P1 terminal.
The wind vane require alignment of the “dead band” or potentiometer gap to North,
either magnetic or true North, to obtain valid mea urement . Alignment can be done at
ground level allowing ea ier in tallation of the en or, but it mu t be checked again
after the en or ha been fully in talled.
The wind en or ba e i u ed to orient the wind vane to North. Normally, wind direction
en or are aligned to true North, rather than magnetic North. True North can be found
by reading a magnetic compa and applying the correction for magnetic declination,
where magnetic declination i the number of degree between true North and magnetic
North.
Alignment involve creating an imaginary line running
through the wind en or from North to South. When thi
line ha been e tabli hed, the mounting ba e of the en or
i rotated until the crew head in the ba e and the crew
hole that i ju t above it in the en or body both point
toward North. Rotate the en or hou ing until the two
crew hole point toward the North.

3.0 OPERATION
The WS-16-A Weather Station collect and log data automatically, requiring little u er
input. Ultimate control, however, i provided by the interactive u er interface, which
allow the u er to direct the WS-16-A to perform certain pecific function by choo ing
one of the ix option offered on the main menu (Figure 3, Page 9).
3.1 Softw re
The firmware in the WS-16-A contain all of the program required to u e the weather
tation with a PC operating in communication mode ( uch a HyperTerminal in
Window ). The WS-16-A and the PC communicate through the RS232 erial interface
cable in talled between the data acqui ition module and a erial port of the computer
(u ually Com 1 or Com 2). To help you get tarted if you are u ing Window
98/2000/XP, we have provided a quick tart di k that automatically open the
HyperTerminal program with all the proper etting for communicating with the
WS-16-A u ing Com 1 or Com 2.

The communication parameter required to interface the WS-16-A to an RS232 data
link are a follow :
Bit per econd 9600
Data bit 8
Parity None
Stop bit 1
Flow control None
Emulation ANSI
