pathpilot pulse output?

I have a tormach 1100 series 3 with ATC.  I have added a coolant blaster called ACCUBLAST which is awesome servo controlled coolant. I am trying to get pathpilot or fusion or Linux to have a pulsed output to the control of the accublast that tells what tool number is in the spindle. The accublast will auto adjust to the tool length I set in it.  I am not a code writer or any good at linux. So I physically need a wire to connect to the accublast from somewhere on the Tormach and electrically need a pulsed signal to represent the tool number in the spindle. 
I am happy to add an external io board or relay or arduino or something to make this work if I cant do it without.  I hope that makes sense. I started this topic at the CNC Zone and they recommended you all for the Job.
Any help is greatly appreciated. 
Thank you

Hi thanks for the reply, I do not need continuous PWM just a number of pulses corresponding to the tool number. I am not sure of the outputs but I do have the manual and I know they offer an additional input output to relay using a USB M-Code I/O Interface Kit if I need something additional but that is $250.   

Yeah I am not sure about the pulse time the literature says it can pick up milliseconds of pulses. I also do not know what remapping is, sorry. 
Here is what someone did with a Linux based machine but not pathpilot. Maybe the below will work with my machine and I just dont know how to implement it.  Thanks again for any advice. 

I will go try at the machine now. I know I can get into terminal.

I can hit ctrl alt x and terminal opens but I dont know what to put in.  like ADMIN or CMD or what to get information to work in the terminal 
terminal says "operator@tormachpcnc:~$ " but if I type HALCMD it just says "command not found"  I am using PP 2.8.3   I tried " ADMIN HALCMD" same response.  I tried "SUDO HALCMD".  I am not sure what you can do in the path pilot terminal or what I need to type first to accept my commands.

Did Peter give you the M208 macro as well? From shuffling files around various computers I lost it a while ago. Amusingly, no one has ever emailed me about LinuxCNC/AccuBlasts from that document. Going through a USB I/O board won't work, mechanical relays would be much too slow to be practical.

Even using the 7i76e's output was iffy, Peter had to make some changes to the firmware to help it recognize the pulses more accurately. I think I was on 1.10, maybe it's better now, but I haven't played with the unit basically since writing that document.
