*In the Nixdorf Mode B or OPOS/JPOS, if CTS is Low, scanning is disabled. When CTS is High, the
user can scan bar codes.

**If Nixdorf Mode B or OPOS/JPOS is scanned without the scanner connected to the proper host, it
may appear unable to scan. If this happens, scan a different RS-232 host type within 5 seconds of
cycling power to the scanner.
