Author Topic: Advanced Cinema Systems shaft encoder pulse rate.. Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 10-12-2009 01:45 PM                     Got one for Clint: What is the pulse per revolution rate of the Advanced Cinema Systems shaft encoder? Got a room with two of them and need to change the pulley ratio to get to 10 pulse/frame.  |  IP: Logged Clint Koch Phenomenal Film Handler Posts: 1435 From: San Luis Obispo, CA, USA Registered: Feb 2002 posted 10-12-2009 03:34 PM                     Wow, that goes back before I came on board with Jack. Anyway, I questioned Jack and from his memory it should have 4 notches which equates to 360 RPM and 24 pulses per second. Jack was impressed that you had two still in service.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 10-14-2009 12:09 PM                     LOL I kinda figured it would go way back. I first met Jack when I was working at Universal Projector back in '84-'85 and IIRC that was about the time Jack had changed the company name to Ultra*Stereo. Yeah, these encoders are still going strong. The location is using a footage counter and needs better resolution so we're going from the current single pulse per frame to ten. Thanks for the help Clint, tell Jack thanks. This BTW is why I have always liked Ultra*Stereo, they always come through when support is needed!  |  IP: Logged
