4 Modes of operation
4.1 Conveyor Tunnel Standalone Mode
In standalone mode no software application development is required. The tunnel is fully
autonomous, and the RFID reader sends automatically the read tags ID N° to the PC. The only
connection between host PC and the system is the serial RS232 cable to collect reader output data
(read tags can be displayed on the PC using Hyperterminal software).

The reader settings (baud rate, data frame format, RFID settings…) and PLC standard program
(ConvoyeurStandardDM_V2.pro) are loaded in the non volatile memory of the reader and the PLC
allowing tunnel to automatically run at power on.

4.1.1 RS232 Serial Communication Parameters
• baudrate: adjustable (9600, 18200 or 38400 bauds) – factory setting = 9600
• data bits: 8
• parity:
• data bits: 8
• parity:
none
• stop bit: 1
• flux
• flux
control:
none
• Frame format: Tag ID in hexadecimal, number of digits adjustable up to 16 (factory setting
= 16 digits)
• Trailer: adjustable – factory settings = carriage return + line feed (\0D\0A)
• Sorting: adjustable – factory settings = sorting activated (tag ID of a read tag is sent only
• Sorting: adjustable – factory settings = sorting activated (tag ID of a read tag is sent only
once by the reader)
Below is an example of frames sent by the reader after 3 tags have been read (factory settings,
frames displayed on hyperterminal)
frames displayed on hyperterminal)
Uniqueness of tag ID can only be guaranteed if Tag ID is transmitted with 16 digits
Medio L200 reader cannot sort out more than 48 tags at a time, if more an additional sorting
sequence must be carried on by the customer application (otherwise the tunnel reader may
send several times the same tags ID)
