Re: WWA8SME Antenna controller for G-5500, G-5400, NOVA,and SatPC32



Hi

Here are a few mistakes I have found with the Far Circuit's board.  They 
have changed the board to make it easier to produce, but they did not 
change the directions. 

C8 was left out of the parts list, it is .01uf
The parts layout on the CD is wrong.  Two C8s and the voltage reg is 
backwards.  Go to farcircuits.net and download their corrected version.
As mentioned the voltage reg is backwards.  Important to check the 
voltage on pin 1 of the IC (5 volts) before installing the IC.
The directions has you matching the 8 pin connector from the Yaesu 
control box pin for pin on the interface board.  Farcircuits has changed 
that also on their board.  My interface was telling my rotor to move CW 
and it would go down.

That is all I found so far.  It is also important to adjust the output 
voltage of the control box to pins 1 and 6 at exactly 4.5 volts when the 
rotor is all the way CW and UP.  This is how the interface knows where 
the antenna is pointed.

Mark Spencer, WA8SME who designed the orignal board has been a great 
help!  Thank You Mark.
