Agfa Avalon VLF laser power supply question


Hi everyone

Got a question about the laser power supply board from an Avalon VLF (60 XXT): the board is controlled by the pelvis board, same that controls the GLV. There is only a 4 pin header connector (J1) between the pelvis board and the laser power supply that sets the laser current and reads the feedback current. Does anyone have the pinout for this connector and know what signal it's using? For example: Analog voltage/current in/out or maybe uses resistance control to set current.

The pin goes to an LM324N Op-amp and i know it's current source/monitor.

Any ideas or maybe someone measured and knows?


It wasn't about replacing but reverse engineering. Managed to do so successfully and figured out the input control and output feedback.
