HF80 Transponder Reader – HSMS, Release 1.3
5.3 Modes
The HF80 reader offers the possibility to work as SECS1 and HSMS
reader. You can easily change between the two modes by switching
one of the DIP- switches on the front panel of the reader.
The second possibility to switch the modes is changing reader
parameter 13. (communication port).
SECS1 uses the serial interface to establish the direction of
communication for passing message blocks. The SECS1 message set
describes the communication between the reader and a host.
If the reader uses the HSMS mode, it works as HSMS-server. That
means that it waits for a connection inquiry of any HOST-PC.
TCP/IP: IP-Address xxx.xxx.xxx.xxx Port 3241
If a connection inquiry of any HOST takes place, the reader initializes
the HSMS-connection, and the SECS II messages defined in the
message set are forwarded from the reader to the respective HOST and
vice versa.
It is possible to operate all readers connected to the network via one or
also via several HOST-PC’s.
But one HSMS reader can only be connected to one HOST at the same
time.
