B875–111 Analog Input, Quick Reference
(Original Document)
Overview
To set up the analog input module properly, an eight-position DIP-switch must be set together with SW5 of a five-position DIP switch located on the left side of the module. These switches determines the input range, output format, number of samples to be averaged, and the types of inputs.

For example, assume that the following values are desired: 5 V input; 0—10,000 counts output; no averaging; differential inputs. Set the switches as follows:
