Commands
Command Response Flow
The command received from the Handy Terminal by the CF Reader/Writer may be different to the response
sent to the Handy Terminal from the CF Reader/Writer, depending on the type of command and the
communications designation.
No Response
If the CF Reader/Writer receives a reset command, it sends no response, performs reset processing,
and waits for the next command.
The indicator will light green when the CF Reader/Writer receives a command. After sending a com-
mand, check the indicator to be sure that the CF Reader/Write has received the command.
Single Response
One response is returned for one command when single auto (SA) is specified in a command for com-
municating with Tags, when commands that are not for communicating with Tags (communications
subcommand, controller control commands, or host commands) are specified when appraisal com-
mands are specified, etc.
Multiple Responses
Multiple responses are returned for one command when repeat auto (RA) is specified in a command
for communicating with Tags.
