Parallel Port breakout boards, motherboards, and dedicated accessories / Upgrading from Sound Logic PC-2 to PMDX-126 & PMDX-107
« on: August 19, 2020, 12:05:56 AM »
I have a Bob Campbell control box using the Cullins Sound Logic PC-2 board. I have run into issues with both the control box and the computer that came with it (running 32-bit Win 7). I would like to build a new control box based around the combination of a 126 BOB and 107 spindle speed controller and an ESS Smoothstepper. The existing box has 2 360W power supplies (24V @ 15A) and 4 Gecko 251 Rev 9 drivers.
I can obviously re-use the Gecko drivers, but I am not sure how to determine the correct power supply. I know that the Smooth Stepper requires a 5V power supply, and if I understand the PMDX-126 manual correctly, it gets fed 115v AC power directly from the outlet. The Gecko's require DC power between 15 and 50 volts.
Should I just add a 5V supply for the smooth stepper and keep the two others that I have, or is there a different rated power supply I should be using? I would like to learn as much as possible doing this so even just links to where I could read more on the topic would be appreciated. Happy to provide any additional information that would be useful.
Thank you,
Lee
