If a number (0.01 to 1.00) is found in the second 6 characters of the Comments field it will be used as the avoidance
radius.
Note: you will not see the waypoint indicator on the NorthStar change immediately during the uploading process unless
you cycle the view to refresh the screen. If you wait, it will catch up eventually.
Hardware Connection
The data cable to connect a PC and NorthStar looks like:
COLOR WA215 PIN DB-9 PIN
RED 18 2
GREEN 16 3
TAN 17 5
This cable can be purchased form NorthStar or constructed by a technician. Note that it is not necessary to have the
exact connector for the NorthStar end of the cable as only 3 pins that are in a row need to be connected. The technician
can construct a suitable partial connector from connector parts that will suffice. You cannot connect the WA215 directly
to a USB port if your computer does not have a serial port. In this case, you must use a serial to USB converter that will
convert the speed and protocol from one form to the other.
The WA535 power cable has a 3 pin round connector with a notch, where, looking at the back of the machine, the pins
are as below. Pin 2 is positive 10 to 40 volts and pins 1 and 3 are ground and are tied together internally. That is, there
should be 0 ohms between 1 and 3. As above, you don't necessarily need the actual connector if you can wire to pin 1 as
ground and pin 2 as +12. A technician can construct a partial connector from connector parts that will suffice. You can
power the unit on the banch with a suitable power brick (a transformer delivering at least 1 amp at 12 volts DC.)
