One dump encoder pulse question more...

Hi, to all

I just tested pair of new encoders I got cheaply.
The encoders are made in Taiwan by Hontko Co. Type is: HTR-HB-8-1024-3-L.
Spec says they are 5V, 1024 pulses per rev, with line driver cirquit.
When I hook them up top my new oscilloscope I got nice differential pulses whitout problem but the edge of pulse is only 3,3V which maybe is too low for my Rutex drives.
Does enyone know if I can make similar pull up with 5v and resistor as step and dir pulse line sometimes need?

Thanks in advance,

Regards Mika.
