[amsat-bb] Fox Delta ST2 with G5500DC? [SOLVED]

I figured out the issue that I was having between the Yaesu G5500DC 
controller unit and the Fox Delta ST2 and wanted to pass along this 
information for the next person that might need it. The wiring pin out 
for the 8-pin male DIN diagram in the manual is wrong. The table below 
is what finally worked for me:

`pin` | function
--- | ---
`1` | Rotate up
`2` | Rotate right/CW
`3` | Provides 2 to 4.5V DC corresponds to 0˚ to 450˚
`4` | Rotate down
`5` | Rotate left/CCW
`6` | Provides 8 to 14V DC up to 100mA
`7` | Provides 2 to 4.5V DC corresponds to 0˚ to 180˚
`8` | Common ground

Also the voltage I observed across the common ground and pin 6 on my 
unit was just shy of 16V, well above the stated value in the Yaesu 
manual.

After getting all the wiring corrected, I was able to perform an EEPROM 
calibration correctly and everything lines up and works now. Hope this 
saves the next ham some time trying to figure this out.
