Reader response: #Done or #Error.
The reader returns an Error message if a valid hexadecimal digit is not substituted for N in Command
#693N.
Note: This command only has an eect when the reader is not in MPRX mode.
694N Select Input Inversion Option
#694N enables or disables input inversion. When inversion is enabled, an open circuit input
is interpreted as a closed circuit, and a closed circuit input is interpreted as an open
circuit. This feature allows greater flexibility in the attachment of external equipment to
the reader inputs. For example, some proximity sensors indicate presence with an open
circuit. In this instance, Command #6941 can enable input inversion so that an open
circuit input indicates a presence. The values for N represent the two inversion options
as shown in Table 25.
Reader response: #Done
