new_zealand_landscapes Posted December 19, 2006 Share Posted December 19, 2006 I am trying to make up a battery pack for my phase one scanning back. I have the following information for the power connection. What I dont understand is what the meaning of DC Com on Pins 1 and 2. ------------------ Pins 1 & 2 DC COM Pin 3 +5Vdc 2.0 amps Pin 4 -15Vdc 0.3 amps Pin 5 +15Vdc 1.5 amps ----------------------------- Any help would be greatly appreciated.

MichaelChang Posted December 19, 2006 Share Posted December 19, 2006 John, it would mean pins 1 and 2 are the reference points from which other pin voltages are measured, also known as Common (hence COM). Example: if you put your volt meter's Negative probe on pins 1 and 2, the meter should read +5VDC on pin 3 (with the positive probe on it), -15VDC on pin 4, etc..

jonathan_gentry Posted December 27, 2006 Share Posted December 27, 2006 I need help with an old Photophase scan back. Please let me know if you can help. -Jonathan Link to comment Share on other sites More sharing options...
new_zealand_landscapes Posted December 27, 2006 Author Share Posted December 27, 2006 Yes what do you need to do I am happy to help. I am using the scanning back for landscapes, and am waiting for a battery. I have to use a voltage converter in my car at the moment. We could start a new subject line in the forum.
