Overview of commands

The ASCII protocol supports the single tag mode with normal addressing. The following
modes can be selected:
● with presence (MDS_Control On)
● without presence (MDS_Control Off)
● without presence including command-dependent antenna on/off (MDS_Control, HF Off)
If the presence check is active "with presence", transponders entering the antenna field are
displayed. The presence of a transponder is signaled by the reader LED being lit yellow. The
presence of the transponder is signaled to the host system using the presence frame. You
will find more information on this in the section ""ANW-MELD" message (Page 19)".
With the passive presence check "without presence", the presence of a transponder is also
indicated by the yellow reader LED lighting up, however no frame is sent to the host system.
In this mode, presence can be queried on the reader by the host with the "SLG-STATUS"
command (mode 0).
