Description
Notes:
•
When this parameter is saved on the reader, a plausibility test is run. If an error occurs, the reader replies
with STATUS = {0x11}.
•
Changes to TRANS-FORM take effect only after writing/saving the configuration block CFG2 in the
EEPROM and resetting the reader.
•
8 data bits and a stop bit always need to be used.
TR-
RESPON
SE-TIME
With this byte, you can specify the maximum response time for transponder commands.
TR-RESPONSE-TIME begins when the reader has received a new command. The reader sends a response
protocol at the latest when the TR-RESPONSE-TIME elapses. In this case, the current commands between
the reader and transponder are aborted. If this time is too short, the interface status "0x83 RF communications
error" appears.
The response time is calculated as follows: TR-RESPONSE-TIME * 100 ms. The range of values of TR-
RESPONSE-TIME is between 1 and 65535.
Notes:
•
"TR-RESPONSE-TIME" has no effect on the protocols for the configuration of the reader and the protocols
for controlling the reader.
•
"TR-RESPONSE-TIME" must be lower than "Block Timeout" in the settings of the COM port of the host.
