Just an FYI the G203V is different in it's timing requirements from the 201-210 drivers:
G203V:
Quote:
Step Pulse “0” Time: 2uS min (Step on rising edge)
Step Pulse “1” Time: 1 uS min
Direction Setup: 200nS before step pulse rising edge
200nS hold after step pulse rising edge
G202:
Quote:
Step Pulse “0” Time: 0.5 uS min (Step on falling edge)
Step Pulse “1” Time: 4.5 uS min
Direction Setup: 1 uS min
20 uS min hold time after Step edge
G201:

Step Pulse “0” Time: 0.5 uS min (Step on falling edge)
Step Pulse “1” Time: 4 uS min
Direction Setup: 1 uS min
20 uS min hold time after Step edge
G210:

Step Pulse “0” Time: 0.5 uS min (Step on falling edge)
Step Pulse “1” Time: 4 uS min
Direction Setup: 1 uS min
20 uS min hold time after Step edge
So the 203V requires 4x as long a LOW signal (2us vs .5us) but only 1/4 the length for a HIGH signal vs the other drives. The direction change is much more efficient being in the nanosecond range versus the microsecond (nano is 1/1000 of micro for those who may get the tiny ones confused). Just observations. These are right from the current manuals (and if Mariss happens to read this, you might want to change the ordering of the specs so all the timings are together and the temp and humidity are together - and maybe add a spreasheet type page comparing all the drives to one another :) )
