Mask Examples
Command
Response
>set Mask = all
Mask (BitLen, BitPtr, XX XX) = All Tags
Command
Response
>set Mask = 8, 0, 03
Mask (BitLen, BitPtr, XX XX) = 8, 0, 03
Command
Response
>set Mask = 16, 0, 00 03
Mask (BitLen, BitPtr, XX XX) = 16, 0, 00 03
Command
Response
>get Mask
Mask (BitLen, BitPtr, XX XX) = 16, 0, 00 03
If the mask length is not evenly divisible by eight, then the last byte of the mask
contains the remainder bits, and they are read from that byte from most-
significant-bit to least-significant-bit. For example, to set a mask looking for three
ones at position 0 in the tag ID, the following would be used:
set Mask = 3, 0, E0
Notice that the mask value specified is E0
hex
(11100000
binary
) and not 07
hex
(00000111
binary
). Matching only three bits off 07
hex
of would match all zeroes.
Autonomous Mode Commands
Autonomous Mode is an operation mode that enables hands-free monitoring of
tags. Setup requires that you issue a series of configuration commands to the
reader. These commands detail how and when to read tags, and then when tags
are found, whom to tell. Once configured, the reader can be left to operate on its
own.
For a detailed description of the Autonomous Mode system please refer to
Chapter 2 of this guide.
AutoMode
9800 | 9780 | 8780 | 9640 | 9774
The AutoMode command turns on or off the auto mode.
Valid command parameters are ON and OFF.
The default setting is OFF.
Changes made with this command take effect immediately.
