Default Galvo driver pinout?

I got a pair of these drivers for each galvo.

There is one thing im confused about, the boards came with a 24V power supply, but there is a set of pins labeled (-15 0V +15) and I wonder if these need 15V power?

another is the IN+ IN- G, I assume those are the signal inputs.
lastly is the galvo connection itself.

can anyone clear that mysetery 15V terminal? or does anyone have or have used this board before?

thank you.

The 15V connection is where you connect your power supply. There are voltage regulators on the galvo driver that step the 24V from your PSU down to 15V.

The IN+ IN- G is the input signal for the x or y galvo from either the outputs of a soundcard DAC or the ILDA pinout.

I have the PT-30Ks and the mystery 15V terminal is actually a 15V output which is for the optional PT-ITRUST dmx/ILDA board that Phenix Technology makes, so if you are not using the PT-ITRUST just ignore it. For answers to all of your questions with the pins refer to the user manual on Phenix Technology's website: Guangzhou Phenix Technology Co.,LTD.

Thank you!
I was wondering who made these boards.
I will read up further on them. I tested these out today using just a square wave for the inputs, the whole set makes some very smooth lines.
but now Im definatly a bit more familair with them.

LOL! Sorry about my reply, I was at work when I wrote it and for whatever reason I couldn't see that pic. Just had a look back here and there it was.. I'm with djpsych on this one. I have a set of those and I have nothing connected to those pins.

Default Re: Galvo driver pinout?

The PT-iTrust 15V supply connector has a discrepancy in circuit board connector label compared to the documentation. And if I use the cable supplied for this between the galvo amp and the PT_iTrust I see the cable connects -15V to +15V. Does anyone know the real pin outs? Miswireing this will definitively blow the board.

I have circled the discrepancy in the image below.
