Azimuth /Elevation interface unit

This unit is the core of the antenna system. In most applications there will be two of these boards located at the antenna. One for azimuth and one for elevation. The boards communicate with the shack unit with 9600 baud ASCII.

Each board, depending on the program in the PIC, will communicate with a different sensor. Currently the board will communicate with home brew AS5040 or AS5045 system (accesses data from the chip directly), the MA3-P12 from US-Digital (interprets the PWM output), the Screwjack solution (Counts pulses), the HH-05/12 (accesses data from the chip direct) and the SCA61T inclinometer.

The old AZ/EL interface unit (above)- outputs ascii to shackunit.
Plug to AS5040 board to left, power and data out to the right
Extra LEDs for magnet alignment.

The revised AZ/EL interface unit (above), a tidier setup that allows for attachment of encoder unit, additional connection for PWM input.
Note the wires to the shack unit or those joining the encoder unit to the AZ/EL are not yet soldered in as I am doing some tests at this time.
The row of 12 interface perfectly between the board. I am using metal spacers about 3mm thick to separate the boards.
