Digital ReadOut version 4.0 - Will read 5V quad. encoders via the 
LPT port 1118628 bytes

DRO version 4.0 is a computer digital readout for linear movement 
or for rotary (degrees, minutes, secs.) movement.  Reads via the 
printer port quadrature square wave 5V encoders that may be used 
to control mechanical movement.

Special requirements: Bi-directional parallel port and making of 
simple hardware interface.  Text files and jpg files show you how.  

To install Digital ReadOut: Create a directory for it and use 
PKUNZIP to extract DRO40.ZIP.  To run the program change to its
directory you made for it and type dro followed by enter.  

Features:
Read up to three encoders simultaneously.
Reads 4 times the resolution of the encoder by counting all 
changes per cycle of the quadrature inputs.
Reset, Preset.
Absolute master mode and four incremental modes.
User selectable between Linear and Rotary readouts.
User customizable unit to count by for each encoder.
Six places right of the decimal point resolutions possible.
Linear backlash compensation.
Millimeter to inch and inch to millimeter conversion.
Reads from most 5V encoders with quadrature square wave 
output.
