You must select the tag type '50' (ICC-...) beforehand in order to read out this
code. If a "read only code" command is executed when the tag type '50' (IDC-...-
1K) is set, the 4-byte read only code for this tag is issued.
Enhanced buffered write read only code (EX --> 24h)
The R/W head constantly attempts to write a read only code. After each
successful write, the response is sent and the system waits until a new tag is
within the detection range. The command then starts again from the beginning.
For more information see chapter 7.3.11.
Extended commands for type IDC-... and IUC
…
tags
Type IDC-...-1K tags can be programmed to read 24-bit information (so-called
special read only code)
very quickly. This is useful for detecting containers in
automated warehouses.
To write the
special read only code
use the commands
SP
and
EP
; to read it
out, use the commands
SS
and
ES
.
