Application Tag Commands
138 Command Set
ChangeConfig
The ChangeConfig command is used to toggle the bits of the G2i* tag’s ConfigWord (see
ConfigWord to Command Bit Address Map table). Specify a ‘1’ in the desired bit location of
the Config Data word of the command in order to toggle that bit.
Note
Different version of the G2i* tags support different features. See tag data
sheet for specific bits supported.
The ChangeConfig command can ONLY be sent in the Secured state, i.e. requires a non-
zero password. Caution should be used when embedding ChangeConfig in a
Tag
Inventory With Embedded Operations command. Since this command toggles the specified
bits, if the tag responds twice (or an even number of times) during an inventory round the
end result will be no change.
