5-7 Tag Communication Command
5-30
5-7-8 Communication Test
To check a radio wave environment, data (256 bytes) is communicated 256 times between the antenna and tag and the communication
status is output. A total of 128 kbytes of data is communicated in two ways. So, it takes a few seconds to execute this text. The com-
munication is not retried.
<Command Format> * A figure below shows the number of characters.
<Response Format> * A figure below shows the number of characters.
DA
Destination (antenna) station number. "00" to "31". This can
be modified in "5-9-8 Station Number Setting".
Initial value "00"
SA
Source (host device) station number. "80" to "89". If only one host device is used, specify
"80".
Command code
T0: Single Trigger
Communication designa-
tion
SU: A tag will be in a sleep state after execution.
DA
Destination (host device) station number. * In the command format, the destination is an
antenna.
SA
Source (antenna) station number.
Termination code
Fixed to "00".
Number of communications
Fixed to "0256".
Radio wave environment
value
"0000" to "0256" (decimal number).
A smaller radio wave environment value shows a better radio wave environment.
(The radio wave environment value is the number of failed communication of total 256 com-
munications. In the communication test, communication is not retried. However, the com-
munication is retried when the communication fails in an actual operation. If the radio wave
environment value is 50 or less, a communication error does not occur in an actual opera-
tion.)
Correct Usage
Check your radio wave environment with this command before operating your system. We recommend you to set the
radio wave environment value to 50 or less.
