Communications with the Host Device
Communicate with the host device only after confirming that the CIDRW Controller has started. Also, unstable signals
may occur at the host interface when the CIDRW Controller is started. When initializing operation, clear the reception
buffer at the host device or take other suitable methods to clear unwanted signals.
The command and response details are given for a 1:N protocol. Just as in the previous command format, the
details for a 1:1 protocol are the same if the SOH, node number, and FCS are deleted.
Value
0100 When this command is received, the system communicates with the ID Tag, and
reads the specified page(s) of data. Any pages up to a maximum of 16 can be
selected.
0200 When this command is received, the system communicates with the ID Tag, and
writes the specified page(s) of data. Any pages up to a maximum of 16 can be
selected.
0300 When this command is received, the system communicates with the ID Tag, and
writes the same data in page units to the specified pages. Up to 17 pages, which is
the maximum number of pages for an ID Tag, can be specified.
0400 When this command is received the system communicates with the ID Tag, and
writes data to the area specified by a first address and number of bytes. A maximum
of 128 bytes can be specified.
10 Sends received data to the host device.
12 Sends the response made immediately before again.
14 Gets the model number, Firmware version, or another parameter.
15 Gets the command code of the last command that was executed.
16 Gets the history of communications from when the power was turned ON (total num-
ber of communications, total successful communications, and total number of failed
communications).
17 Clears the communications history.
40 Measures the noise in the vicinity of the CIDRW Head.
7F Resets the Amplifier Unit.

Description
Command execution is completed normally.
There is a mistake in the command format. (For example, the command
code is undefined, or the page or address specification is inappropriate.)
Noise or another hindrance occurs during communications with an ID
Tag, and communications cannot be completed normally.
Correct data cannot be written to an ID Tag.
Either there is no ID Tag in front of the CIDRW Head, or the CIDRW
Head is unable to detect the ID Tag due to environmental factors (e.g.,
noise).
in an area in which the ID Tag could be read but not written.
The ID Tag is in a status where it cannot execute command processing.
An inapplicable ID Tag has been used.
