CHAPTER 8: GENERAL I/O
NOTE: The datasheet is the first document you need to refer to for model-specific information
related to XL4 OCS models such as pin-outs, jumper settings, and other key installation
information. Visit our website to obtain datasheets, user documentation, and updates.
8.1 Overview
The XL4 OCS is a compact unit that contains high density, very versatile I/O. Using the I/O
properly requires wiring to the proper terminals, configuring jumpers inside the XL4 OCS unit
on some models and configuring Cscape properly. This section will offer some tips and
suggestions to configure the I/O properly. For the register mapping of the I/O, refer to the Index
at the end of this manual for the pages referencing register mapping.
8.2 Removing the XL4 OCS I/O Cover
Some I/O configurations require jumper settings to be changed inside the XL4 OCS unit.
Examples of these settings are setting positive or negative logic on digital inputs or setting
current or voltage on analog inputs.
Each XL4 OCS I/O jumper is set to a factory default. Refer to the data sheet for your XL4 OCS
model to find the default setting to determine if a jumper change is necessary for your
application.
To remove the I/O cover of the XL4 OCS, remove the four (4) Phillips screws from the I/O back.
It may help to place the XL4 OCS unit face down on a clean work surface. Once the four screws
are removed the I/O cover can be lifted straight off.
