A Reader can access 6 types of inputs: a discrete input, DeviceNet
input, package detect, ASCII command, timer, input timer. Use
these inputs as a trigger for decoding, scanning, messages and
packages.
Discrete Input
You can install two discrete input modules in the Reader’s wiring
base. These modules are available with a variety of voltage and
current ratings (refer to the AdaptaScan user manual). You can
configure discrete inputs to be ON when the input is either a high or
low state. In addition, inputs can be assigned a delay, debounce
filter, and have a cyclic operation when ON. An input can be used
by any Reader on the same network.

DeviceNet Input
The Reader DeviceNet communications support up to 7 discrete
inputs. Use these inputs as trigger sources for functions such as
decoding, message trigger, auto-load trigger, etc. Refer to page
9–13 for descriptions of DeviceNet I/O.
