Hello,

I've bought the 1057 High speed Encoder, Along with a Rotary Encoder (ISC3004). However I'm a little confused with the wiring and don't want to destroy either product.

The Phidget wiring as described on the website is :

black : ground
green : not used
white : A Channel
red : +5V DC
brown : B Channel

The Rotary Encoder is manufactured by HEDSS and the pdf describes it's cabling as :

Red : +5V DC
Black : 0V
Green : Sig A
Brown : Sig A (with a little line over the A)
White : Sig B
Grey : Sig B (with a little line over the B)
Shield : Not Connected

The cable as received only actually has

Red
Green
Black
White
Shield ( a silver mesh rather than a cable)

So I'm a little stumped on how I should hook everything up. The HEDSS encoder as supplied by Phidgets looks as though it's been altered, but that still leaves me without a brown cable on my Encoder.

Can anyone help me on how I should connect this up ?

Photographs attached.

Encoder:Encoder Board

Black:Black
Red:Red
Green:White
White:Brown

The little bar over the signal line just indicates that it is a complimented version of the signal (inverted).

Brilliant .. thank you !

If that does not work, let me know it may be an issue with the type of encoder you have. It is possible that you have a differential encoder which would not be compatible with the 1057.

Bugger .. I hope not .. this is the model I bought :

That shouldn't be a problem, that's the encoder we sell. As far as I know there shouldnt be more than 4 wires on it though.

There is a wiring guide there for how to connect it.
