Power-Off-Terminal (P.O.T. Option) – If your scanner uses Power-Off-
Terminal (P.O.T.), the scanner must be connected to the host terminal
to verify the scanner operation. The P.O.T. option requires an
interface cable designed to supply power as well as transmit bar
code data.
To verify the scanner operation with the P.O.T. option follow the
steps in the section Power-Up Procedures. Then refer to the previous
paragraphs, Passes Selftest or, Fails Selftest, depending on the
scanner's behavior.
