Commands
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.
Set tag ID code (TI):
This command restricts the execution of all other read/write commands to the read/write tag
with the specified ID code. This also applies if another read/write tag is located within the
detection range. A targeted response is achieved from the read/write tag as a result.
<ByteNum> = 0h: Do not make a selection. An ID code is not specified in the telegram.
<ByteNum> = 8h (System IQ): Make a selection. An ID code must be specified in the telegram.
<ByteNum> = 0h deletes this filter.
Fill data carrier (S#):
The word number <WordNum> of fill signs <Fill Sign> is written to the read/write tag from the
specified start address <WordAddr>.
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
.
If
SP
or
EP
is used to write to an IDC-...-1K tag, the tag is then locked. If you wish to write to the
tag again using standard commands, unlock it using the command
SI
.
IPC11:
<FixLen>
=
5
<FixType>
=
'02' ASCII (30h 32h), the read only code cannot be
changed
'11' ASCII (31h 31h), the read only code can be
overwritten
IDC-...-1K:
<FixLen>
=
7
1
<FixType>
=
'52' ASCII (35h 32h), the read only code can be
overwritten
1. The first 3 bytes are hexadecimal (0h ... Fh), the last 4 bytes are decimal (0d ... 9d).
Command:
TI
<Ident channel><Bytenum><ID code> <CHCK><ETX>
Response:
<Status><Ident channel><CHCK><ETX>
Note!
The TI command only adjusts a setting in the reading head. There is no HF communication
with the read/write tags.
Command:
S#
<Ident channel><WordAddr><WordNum><Fill Sign><CHCK><ETX>
Response:
<Status><Ident channel><CHCK><ETX>
Length of the
special read only code
:
■
Tag of the type IDC-...-1K:
48 bit
■
Tag of the type IUC:
96 ... 240 bit
