ENABLE - Lo

#1
Hi, Jerome
My board works with signal ENABLE = 0.
Can You help me?
Configuration:
PC Toshiba Satellite Pro 4200 with W98 >:D<, but with LPT!
CNC SPARTIA by Papy Kilowatt (in progress)
board with Toshiba TA8435H.

With regards, ZbigPL

My englisch is poor, so my sentences are shorter then ideas.
Jedicut send signal ENABLE =1 (pin 17). My drivers are activated by signal ENABLE = 0.
I had to install inverter (75LS05) at pin 17, but software solutions would be better.

Hi!
Once more - configuration:
Windows 98 SE
Board (without timer) input signals (TTL):
ENABLE - active Low
CLK (min 1 µs)
DIR

Using CncNet98.dll or VisualCNC.dll rotational speed is constant and low (about 2,5 turns/10sec) independent on "Speed". I can control direction of rotation.

MaxCom.dll do not work (Win98?).

With MaxCom_XP.dll(?!) I can control the rotational speed ("Speed">80000) but motor not react on signal DIR.
Manualy conecting line DIR to 0V or 5V changes direction.
Voltage levels (0,24V/4,24V) on line DIR are identical with CncNet98.dll and MaxCom_XP.dll.
Do you have some solutions?
