621 Select Predefined Output Control (Factory Default)
See “410N Select Unique ID Code Criteria (Anti-passback Feature)” on page 7–81.
Command #621 configures the reader for predefined output mode. In this mode, both output lines
– output0 and output1 – are automatically asserted upon receipt of a valid unique tag ID. The output
line remains asserted for the time specified by output pulse duration ( #67N Set Output Pulse
Duration ). Any direct control command ( #620N Output Control) automatically disables the
predefined output mode.
Note: In Wiegand mode operation, the sense outputs are not controlled by a predefined output
mode.
