AutoLoad Input Module Application (powered externally)
Figure H.2 illustrates the AutoLoad Input module application that is
powered externally. An AC/DC input module is installed in position
8 of the I/O Module Board. A push button (normally opened contact)
provides input to the module to load bar code data into the match
code table. The module and switch receive power from an external
AC or DC source.
!
ATTENTION: To guard against enclosure damage,
align the conduit so as to prevent unnecessary stress on
the enclosure walls.

AutoLoad Activated by Aux Port Connector
Another way to activate the AutoLoad function is by connecting a
push button (normally opened contact) directly to pins 17 and 25 (or
K and L) of the AUX port connector. This method does not require
an I/O Module Board with installed input module or a power
source.
