chronous interface can be defined.

P:
(HostInterface.Serial.Parity)
Kind of Parity
b00:
no Parity
b01:
even Parity
b10:
odd Parity
b11:
- do not use -
D:
(HostInterface.Serial.Databits)
Number of Data Bits
b0:
8 Data Bits
b1:

(
HostInterface.Serial.Stopbits)
Number of Stop Bits
b0:
1 Stop Bit
b1:
- do not use

Note:
Changing of TRANS-FORM only becomes effective after writing / saving configu-
ration block CFG1 to EEPROM and reset of the Reader.
Always 8 Data Bits and 1 Stop Bits should be used
TR-RESPONSE-TIME:
(AirInterface.TimeLimit)
By means of this parameter the maximum duration for the Transponder command can be de-
fined.
The TR-RESPONSE-TIME starts after the Reader has received a new command. At the
latest after the TR-RESPONSE-TIME elapsed the Reader will send an answer protocol. In
this case, the current commands between Reader and Transponder are aborted. If this
time i
s too short the Interface Status “ 0x83 RF Communication Error“ will appear.
max. response duration
TR-RESPONSE-TIME
0...65535 * 5 ms

A reasonableness check is performed by writing this parameter to the Reader. If an error occurs the Read-
er answers with STATUS = 0x11.
