Specific features in the operation of an RFM/RFI
When using the MA 258
i
in connection with an RFID device, we recommend a data width
of at least 24 bytes to be able to transmit information to or from the reader in a telegram.
Shown here is a sample telegram for a write command in combination with an RFID device.
Notice!
Also note that all characters which are sent to a transponder are hex-encoded ASCII char-
acters. Each of these (hexadecimal) characters is, in turn, to be handled as an individual ASCII
character and converted to hexadecimal format for transmission via the fieldbus.
