Description
Physical interface
Physical interface setting. Only possible with RF38xR.
Baud rate
Transmission speed setting. Applies to scan mode, test mode, and frame communi-
cation.
Parity
Parity bit setting. Applies to scan mode, test mode, and frame communication.
Data record
Combination of data that the reader automatically transfers to the host in scan mode.
User data start address
Specification of address from which the user data should be read ("user data" set-
ting).
User data length
Specification of amount of user data that should be read ("user data" setting).
Data format
Setting for data transfer type: Bytes are transferred as binary bytes or are converted
into two ASCII characters. This parameter does not apply to the separator or end-of-
text character (binary). This parameter does not apply to frame traffic either.
Separator
Setting for the separator transmitted between data when "UID + user data" is config-
ured. Not used when "UID" or "user data" is configured.
End-of-text character
End-of-text character transmitted at the end of a data set; separates data from differ-
ent transponders.
Byte order
LSB is transmitted first (within the block size) This parameter applies only to user
data.
"Data record" parameter, UID
"Data record" parameter, user data
End-of-text character
End-of-text character
