"Write Read Only Code" Command for Type IPC11 and IDC-...-1K
Read/Write Tags
Tags IPC11 can be programmed to behave like the IPC02 read only tag. To do this, use the
commands
SX
and
EX
. The code is read when tag type '02' or '11' is set with the commands
SF
and
EF
.
Tags IDC-...- 1K can be programmed to behave like the ICC read only tag. This programming
occupies the first 8 bytes in the tag and occurs when the tag type '50' is set with the commands
SX
or
EX
.
This code is read when tag type '52' is set with the commands
SF
or
EF
. If you use the
command
SF
or
EF
when tag type '50' is selected, the 4-byte read only code of the tag is
issued.

Command:
Response:
The R/W head makes only one attempt to write a read only code.

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
