Chapter 12
Digital I/O
XL™ Series Digital I/O 12-1
12.1 Digital I/O Overview
The digital I/O options are very flexible, allowing them to be used for a wide range of
applications. The digital I/O can be uses when a status input or a control output is required.
These two pins can be configured totally independently of each other and can also be used
together for applications using a quadrature input or to simulate a quadrature output.
12.2 Digital I/O Menus
Built in menu structure: Digital I/O Options Menu. The menu for digital I/O 2 is the same as
below.

Test Quad Out?
Built in menu structure: Encoder Input and Output Options Menu.
Sensor Input Setup-> Encodr Input Setup-> Enc Out Src [None ]
Encodr Val[X.XXX ]
Encodr Slp[0.01000 ]
The XL™ can use the two digital I/O pins to connect to a quadrature shaft encoder such as the
Handar 436A, or to simulate a quadrature shaft encoder. For proper operation with a shaft
encoder that increments clockwise, the phase A signal should be input into pin 1 and the phase B
signal should be input into pin 2.
