in all readers. In this example it is determined that an IAG attenuation setting of 6 dB 
(#64606) prevents a reader from activating a tag in an adjacent lane.

65 Reset Power Fail Bit
Command #65 resets the power fail bit to 0. The bit changes from 0 to 1 when power 
is restored to the reader. Upon reader power-up, the host transmits either command 
#65
 or #63 Reset Reader to properly initialize this bit. The current state of the power 
fail bit may be displayed. Refer to 
 for 
more information.
Reader response:
Done
66F Load Default Operating Parameters
Command #66F loads all the factory default operating parameters except RF operat-
ing frequency. Refer to 
tings” 
for a listing of the defaults.

67N Set Output Pulse Duration
Command #67N sets the output pulse duration for the command #621 Predefined 
Output Control. This command specifies the length of time that output line(s) will be 
asserted upon receipt of a valid and unique tag ID. The factory default setting is 228 
ms. The variable N specifies an output pulse duration of 48 ms to 752 ms.
Uppercase or lowercase characters are allowed for N; for example, hex digits A 
through F or a through f. The command numbers and corresponding output pulse 
durations are shown in
