If you mean linear scales, they are connected exactly the same as a rotary incremental encoder, the only thing you have to watch for is to make sure the output is differential square wave, some, especially some heidenhain types are sinewave output, some are also available that have a fiducial marker at one end that serves as a homing pulse.
