Operation
R - Automatic read The external input is used to trigger an automatic read action. The R command
sends the read data to the host. The host then has to confirm the message.
Depending on the readmode configuration (parameter 1: readmode), the reader
reads the following pages:
Reading more pages (readmode "tag" or "whole"): protocol is repeated. The end
package includes the command 'R' and the source address '0'...'E'
No acknowledgement from the host: information is repeated with the following
parameters (parameter 5: RS232 delay time; parameter 6: RS232 maxrepeat)
Reading not possible: repeated read time frame (parameter 3: r/w delay time;
parameter 4: r/w maxrepeat).
Reading again not possible: tag sends error message no tag (4) to the host.
The delay time for the presence sensor is configurable (parameter 0: sensor
delay).
An automatic reading is only possible if all messages that have to be confirmed
have been confirmed by the previous read, or if the waiting period (rs232
repeattime) has expired after the last sending (rs232 maxrepeat).
readmode = page (0) sequential read for different pages (parameter 2:
readpage)
readmode = tag (1) read a tag until the end character ('E' - end
character or 'F' empty) in ID bit 0…3
readmode = whole (2) read the whole tag (all pages)
