Hood,

Thanks very much for your feedback. I am contacting Vista and hope that they can provide a modified version of this sensor so it could easily be hooked up to the index port and pin. Do you think I would need an external power supply or would the pin provide the power needed.

The ESS be able to  supply it if it is 5v, if I recall (been a while since I set up an ESS) but I think you can configure pin 26 on each of the ports to supply 5v.

Hood,

I've been watching your posts for a long time and I need to say that it's great to have someone with your knowledge taking time out for the ones that struggle (like myself). You have put me on the right track to get my problem fixed.

A special thanks to you!

I got some great help when I first started all these years ago from John Prentice, Brian Barker  and others, I am just repaying that kindness shown to me
There are many people on this forum who selflessly help out, it is a great resource.

Hood,

This is a bit of a shot in the dark for me, but I wonder what you think of this idea. I've got 2 of these speed sensors. One doesn't work (I think the USB connector is a problem). I'm thinking of cutting the USB end off and try to set up this sensor to the standard pin configuration required for Mach3 threading. I'm quite sure that it is a USB 2.0 plug which only has 4 wires.

1 VCC Red +5 VDC
2 D- White Data -
3 D+ Green Data +
4 GND Black Ground

Can you give me your thoughts on where I should connect the 4 wires? (I think you already solved the 5v wire with pin 26

I'm willing to try even if it does not work.

Ray

I am not sure but I think there may be a circuit board somewhere in the sensor that is USB capable, if so then it wont be as simple as cutting off the plug and connecting the wires. Probably best just waiting for a reply from Vista, dont want you blowing up the ESS.

Hood

Good plan Hood. I already got a response from Lee (Vista) and he's looking into it.

Ray

I have heard they had good service
Fingers crossed it will be easy.

Hood,

Until I hear back from Vista...

Could you give me a sketch on how to hook up the Optek OPB916B sensor and the 220 Ohm limiting resistor for the LED?
I need to know where to connect all the 5 wires, and associated parts.
I'm "NOT" an electronics guy... so please hold my hand with the sketch you might provide.
I'm sure others like me will be grateful.

Ray

Blue wire will go to an input on the ESS.
Red wire will connect to the resistor and the other side of the resistor connects to 5v
White wire connects direct to 5v
Black and Green wires connect to the 0v.
