W2DRZ Controller board. See below for further description - View Schematic
The PICC 16F877 processor is in the center. It and all other IC's are mounted in sockets for easy replacement in case of damage. The 5 LED's are status indicators for use when checking out the controller. Viewing the LED's is not required in normal operation. The LED's shown are mounted standing up on their leads, but would normally be mounted flush to the board. From left to right, the 5 connectors in the front are listed below.
| Left | Female DB9 | For 9600 baud connection to controlling PC. Use a standard serial cable, female to male connectors. |
| Left Center | RJ45 | Female 8 pin modular data jack - Input for Incremental encoders. |
| Center | Male DB9 | Auxillary connector for Parallel or Mouse interface and for PICC programming and debugging. |
| Right Center | RJ11 | 6 pin modular telephone jack - Input for Absolute encoders. Matches US Digital A2 encoder cabling. |
| Right | DIN 8 Jack | Input for +12 VDC, Outputs to drive position control relays, A/D Elevation and Azimuth inputs. |
Click on the links in the table for pinouts for all the connectors.
| At the front of the board (back side of the picture above) is a push button and a set of 4 dip switches. These are only needed when operating the controller without a serial connection to a PC, and with an attached LCD display unit: More information on LCD attachment and use of the push button and switches. |
