Aerotech Ensemble Epaq - Line Driver Encoder (Standard)

Installation and Configuration Ensemble Epaq Hardware Manual
2.3.1.1. RS-422 Line Driver Encoder (Standard)
The standard encoder interface accepts an RS-422 differential quadrature line driver signal in the range of 0
to 5 VDC in line driver format. It allows up to an 10 MHz encoder signal (25 nsec minimum edge separation),
producing 40 million counts per second, after times four (x4) quadrature decoding.
An analog encoder is used with the -MXU or -MXH option (refer to Section 2.3.1.2. for more information).
