Yaesu Control Box Wiring
The Yaesu G-5400B, G-5600B and G-5500 controllers have an 8-pin DIN connector on the back. The schematic for the rotator shows the connector, but doesn’t make it clear what each pin does.
The figure above is shown looking at the back of the rotator controller. The pinout is shown below. The wire colours correspond to my build:
| Pin | Signal | Colour |
| 1 | Elevation-FB | Orange |
| 2 | Right | White |
| 3 | Up | Yellow |
| 4 | Left | Brown |
| 5 | Down | Blue |
| 6 | Azimuth-FB | Green |
| 7 | +VE (~17V unregulated) | Red |
| 8 | Ground | Black |
Check the cable before you plug anything in or out, since you don’t want another job repairing the Yaesu box too!
