Voltage

When voltage is selected as the wind speed analog output, the
output from WMT700 varies linearly from 0 VDC at 0 miles per
hour to 1 VDC at 125 miles per hour. In SI units, the voltage
varies linearly from 0 VDC at 0 meters per second to 1 VDC at
55.88 meters per second.

Figure 49 below shows the voltage output when an adapter cable
for voltage output (227571SP) and a WS425 cable are used. With
WMT700, the wind speed signal appears at pin 15 (violet) of the
adaptor cable. The violet wire must be connected to V read
channel, and the pink wire must be connected to the analog
ground.
