Commands
Enhanced buffered write fixcode (EX)
Command:
Response:
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.
Type IDC-...-1K tags can be programmed in such a way that they are compatible with the type
ICC-... read only carriers. This programming occupies the first 8 bytes in the tag. The read/write
commands can be used to access the remaining memory.
You must set the tag type '50' in order to program type IDC-...-1K tags. To do this, transmit the
command
SX
or
EX
.

IPC11:
<FixLen> = 5
<FixType> = '02' ASCII (30h 32h), the read only code cannot be changed
