DRO

Four Channel DRO (Direct Read Out)

Each encoder channel has a dedicated microcontroller, this feature gives it a high speed encoder tracking ability.

It will track at up to 30 KHz ! All four channels are controlled by a main chip. The main chip takes care of calculating values for the LCD display.

The main controller uses 32 bit counters so there are no practical limits for it's use.

I used encoders from US Digital. The unit will accept different encoder settings for each channel, which means it can use surplus encoders, you know the kind you find only 1or 2 of and never a set.... :-) !

The keyboard is a simple 4X4 as you can see I added the Esc, Minus, Backspace and decimal point.

There is a RS-232 port which allows easy setup for lesser used features such as Encoder specifications, lead screw tpi (if used) , the more common user input such as Preset for any axis can be entered from the local keyboard also.
