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.
