SmartPass® Integrated Reader 2450 MHz (High Voltage) System Guide
Command 693F disables the RF timeout. The reader will turn RF off immediately
following the acquisition of a valid tag, whether or not it is unique. This control
algorithm may be used in Wiegand mode to ensure that the tag data is transmitted
once and only once per presence on both serial and Wiegand ports.
Uppercase or lowercase characters are allowed for NN (i.e., hex digits A–F or a–f).

694N Select Input Inversion Option
Command 694N enables or disables input inversion. When inversion is enabled, an
open circuit input will be interpreted as a closed circuit, and a closed circuit input
will be 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 an open circuit input will indicate a presence. The values
for
N
represent the two inversion options.
