01 Dec 2003 2:30 cable length for PC interface |
|
|
|
|
Hi,
I want to build a PC interface to control 3 stepper motors using stepper driver ICs.The length of the parallel port cable is a problem as it can't be more than 3 meters.Is there any way to ensure that i can increase cable length without affecting the operation of controller ?
Is it possible using USB interface or any other way ??
how about RC using parallel port?
Thanks in advance

hi coolchip
sure u cannot take long - even hi quality - LPT cābles
the simplest way is to take short cable from PC to your control card and to take long cāble from control card to stepper motor :sm15:
of course u can build USB card, the easiest way with RAVAR-like module with virtual port for a RS232 control

I would say that depends on the driver side of your parallel port.
Maybe you could use a flatband cable where you use each second lead as a GND wire to seperate and shield the wires you are useing against each other.
Try it hope you are lucky using this ...
best regards

| Also, you can build a repeater with 74HC244.
