Enhanced Write Words EW
This command continuously attempts to write <WordNum> 32-bit words from the
address <WordAddr>. If the command was executed successfully, a status 0 is
reported to the control interface. If there is no tag in the measurement range, or if
the tag leaves the measurement range, a status 5 is reported to the control
interface.
Example:
EW1000101ABCD continuously writes the 4-byte long word "ABCD" from
memory address "0001".

Configuration Commands
The response to a configuration command is a status message from the
read/write head. During the read operation, a status message and the
corresponding data are received as the response.
7.5.1
ChangeTag Command
This command tells the R/W system with which tag type to communicate.
Example:
CT180 sets the tag type for IDENT
Control
channel 1 to IUC80
CT180 sets a generally valid tag type, which allows the read-only code to be read
out for each tag, and therefore provides information about the chip type of the tag.
Command: EW <ChanNo> <WordAddr> <WordNum> <Data> <CHCK> <ETX>
Response:
<Status> <<ChanNo> CHCK> <ETX>
Note!
The
memory bank MB
parameter defines the bank which this command
accesses. .
Note!
16-Bit Read/Write Commands
The read/write commands SR, ER, SW, and EW are interpreted as 16-bit versions
by means of a preceding # symbol.
The 16-bit read/write commands behave in the same way as the 32-bit versions.
■
16-bit commands write or read a word with a length of 2 bytes.
■
32-bit commands write or read a word with a length of 4 bytes.
Example:
#SW1000202ABCD corresponds to SW1000101ABCD
Command: CT <ChanNo> <TagType> <CHCK> <ETX>
Response:
<Status> <ChanNo> <CHCK> <ETX>
Default:
80
