Fox Delta ST2 Satellite Antenna Tracking Interfcae using PIC16F876A

Click the picture to enlarge

 

ST2-USB is an advanced Satellite Antenna Tracking Interface for Yaesu (Or similar) Rotor Controllers based on LVB Tracker Firmware. Project uses PIC16F976A, 28PIN DIP. Firmware uses full A/D and EEprom capability of 876A and make setup a smooth process.

ST2-USB measures 14x8cm and is designed on a double sided PTH board. Its same as ST2-RS232 except that it has built-in USB interface using FTDI-232RL chip on a small carrier board. FTDI232RL is in a SSOP28 package. This package is hard to solder by most homebrewers. I made a small board with standard 0.1inch headers on which  FTDI chip will be pre-soldered.

Screw Terminals are used for Rotor Connections to simplify installation. 

ST2-USB has Bi-Directional data flow, from PC to ST2 & St2 to PC. An FTDI232RL chip is used for USB connectivity. You will be required to install FTDI USB drivers which are available from FTDI website.

ST2 and ST2-USB supports GS232, Extended GS232 and Easycomm commands, making it a suitable interface to use with NOVA, SatPC32 and many more, having above interface servers.

ST2-USB can be powered from USB port or from Yaesu Rotor Controller. A three pin sil header is provided for power selection.

Kits are supplied with LCD and 4 Push Button Keyboard, keeping in mind Operation at Radio Amateur Stations.

ST2-USB Kits & Assembled now includes a free powder coated metal case.
