4.4 - Dip Switches
The DIP switches are used to provide a built-in termination to both the
MJ1 port and MJ2 port if needed. The termination for these ports should
only be used if this device is located at either end of the multidrop/daisy-
chained RS-485 network.

The I/O is mapped into OCS Register space, in three separate areas
Digital/Analog I/O, High-Speed Counter I/O, and High-Speed Output
I/O. Digital/Analog I/O location is fixed starting at 1, but the high-speed
counter and high-speed output references may be mapped to any open
register location. For more details, see XLE/XLT OCS User’s Manual
(MAN0878)
