66F Load Default Operating Parameters
Command 66F loads all the factory default operating parameters. Refer to Table 9-1
for a listing of the defaults.
Reader message:
Done all parameters loaded OK
Error if any parameter load failed
67N Set Output Pulse Duration
Command 67N sets the output pulse duration for the predefined output mode
command (command 621). This parameter specifies the length of time that output
lines(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 from
4 ms to 752 ms. Actual pulse length output of the reader may vary from the
specified value by up to 4 ms.
Uppercase or lowercase characters are allowed for NN (i.e., hex digits A–F or a–f).

For example, command 67F specifies an output pulse duration of 752 ms.
Additional IDs may be acquired during the selected output pulse duration; however,
the timing will be restarted upon each successive ID acquisition. This command
should be used with discretion. For example, when the tag acquisition interval is
short compared to the selected pulse duration, distinct pulses may not be generated.
The reader will return an
Error
message if a valid hexadecimal digit is not substituted
for
N
in command 67N.
