Configuring the Interface
Scan the programming barcode from this section which selects the appropriate interface
type matching the system the reader will be connected to. Next, proceed to the corre-
sponding chapter in this manual (also listed in
Table 1 ) to configure any desired settings
and features associated with that interface.
NOTE
Unlike some other programming features and options, interface
selections require that you scan only one programming barcode
label. DO NOT scan an ENTER/EXIT barcode prior to scanning an
interface selection barcode.
Some interfaces require the scanner to start in the disabled state
when powered up. If additional scanner configuration is desired
while in this state, pull the trigger and hold it for five seconds. The
scanner will change to a state that allows programming with bar-
codes.
