Timing Diagrams for RFID
The following timing diagrams show how applicator signals function while an RFID label is
printing and being programmed in Mode 1. For more information about Single and Double
signal modes, see ^RS on page 108.
Single Signal Mode
Figure 9 and Figure 10 show the applicator signals for label formats using programming
positions other than zero.
Figure 9 • Single Signal Mode, Good RFID Tag
Figure 10 • Single Signal Mode, Bad RFID Tag
