Command #693F disables the RF timeout. The reader turns off the RF immediately
following the acquisition of a valid tag, whether or not it is unique. This control algo-
rithm 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.

varies depending on the operative tag read mode and the type of tag in the read field.
Values listed in the middle column of Table 7-19 assume an ID operational tag read
mode (64-bit ID data from eGo tags, ignore ATA tags) and an eGo tag in the read
field. Values in the right column of Table 7-19 assume an ATA operational tag read
mode (reads ATA data from ATA tags) and an ATA tag in the read field. Actual pulse
length output of the reader may vary from the specified value.
