Hello,

I just got one 2012 DSP controller (AWC608) and I downloaded the connection guide from this forum but I can't find the pinout for the input and outputs from IN1 to IN6 and from OUT1 to OUT4, I'm guessing those are for air blowing control, interlock, e-stop, etc, which are options I want to use, if someone has information on the function of these pins please send it to me, the card only shows IN/OUT, there's no description of the pins and I'd prefer it if I don't have to figure each pins function by myself

Thank you in advance

I too have never found any info about this. However I can tell you pin1 is for the air assist, but that's the only one I know.

Please give me a couple day to get the info for the pin out. I have tested it while I was in State and I forgot to include in the manual somehow. I remember I may posted it somewhere.

Anyway, just give me a little time to uncover it. FYI, finding Internet here is troublesome...either slow oR blocked!

I would also like that information!

Would be nice to have everything connected to the dsp like:

water flow safety switch
water temp safety switch (i've got a seperate temperature controller with a 0v/5v at a specific temperature that I want)
air assist relais
main fan relais

Waiting for the info, thanks!

The 2 laser outputs have PROTECT pins which are to be used with your water sensors (temp and flow).

Air assist relay goes on pin 1, and you could also put the main fan on the same air assist connection (with it's own relay). The air assist turns on when the job starts, and off when it finishes, and so will your main fan.

Right! I did this same thing. I built a small timer circuit that runs the fan for an additional 1 minute after the laser finishes, just to do a better job of clearing the smoke.

and how do you connect the protect pin?

Is it a open/closed system? So let say:

link to ground : laser off
no link to ground: laser works

or must put 5 volt on the protect pin to shut off the laser?

I think most use the protect pin on the laser power supply. This pin must be grounded for the laser to operate. So cover switches, water flow, and other protection switches are wired in series from ground to the protect pin on the power supply. If any switch opens, the laser shuts down.

Anyone know what WLP (pin2) on the Laser connectors are?

What about outputs? What are the outputs for?

I've been trying to hook up the water protect and the dsp is saying "waterprotect" on the screen.

But now. how do I hook up the flowvalve so that is works when the water is flowing?

It should be simple but for some reason it is not working.

Bumping this trying to find the info

Is there a pin-out on what the various IN and OUT ports do on the DSP?

Thanks,

Paul

This is on my list of modifications but I haven't quite got there yet. According to the manual, you use pin 2 marked "PROTECT" on the Laser 1 or Laser 2 connection blocks. This input is high triggered meaning that when it is low (0v) there is normal operation. When the input is high (5v or close to it) then a water protect state is triggered and processing stops. I would use a volt meter and check your water flow valve (detector) to see if is providing 0v when the water is flowing and 5v when the flow stops. There are a couple of different flow detectors out there, some provide pulses so they can also measure the rate of flow and some are simply yes/no to indicate that there is or is not flow. If yours is the pulse type, you will need some circuitry in the middle to determine the flow has stopped. Otherwise, on the positive edge of every pulse it will kick in the water protect and the pulses happen so frequently that I believe it would appear to be in the protected state all the time. Some yes/no detectors will provide 5v when the water is flowing, you will need some intermediate circuitry there as well since the output from the flow detector is oposite of what the input is expecting. It would help a great deal to know what flow detector you are using. Again, this is just based on my research so I will defer to some of the more knowledgeable members.
