Yaesu G-5500 supports both manual and automatic control. However, it is necessary to control it by PC in order to obtain better accuracy in its movements.

An interface to connect the PC with the rotator is needed; we are using  LVB Tracker system.

The following schematic shows a schematic of LVB Tracker:

 

Here is the c code of the PIC controller: lvbtracker.c

The hex code: lvbtracker.hex

Once the PCB is designed and fabricated, and the microcontroller is programmed, we would recommend testing its behavior in a PC. Click here for further information.

The protocol GS-232 is used by this controller and its compatible with the major of satellite software.
