Note: The Prox–SU reader does not use this parameter.
Card notification delay
This byte defines the minimum time between the notifications of card movement:
Time unit = 100 ms
Communication time out with GemCore POS Pro
This byte defines the internal communication time-out with the GemCore POS Pro chip
controlling the contact interface:
Time unit = 10 seconds
Load MIFARE
®
Keys security option
This byte defines the Load MIFARE
®
keys security option:
00h: security option off
01h: security option on
When the Load MIFARE
®
keys security option is set on, the PC/SC “Load Keys” command
must be used with an additional secret transport key. Refer to the “Load Keys” paragraph for
more information.
Contactless automaton parameters
Automaton timing
This byte defines the timing of the contactless automaton scanning for contactless smart
cards:
b0-b3: periodic time to search or check for a card presence (unit = 100 ms)
0.1 sec to 1.6 sec (0 is not allowed)
b7-b4: release time after the last host command (unit = 1 second)
1 to 16 sec (0 is not allowed)
Extended ATQB support
This byte defines the Extended ATQB support option as defined in the ISO14443 standard:
00h: Extended ATQB is not supported
01h: Extended ATQB is supported
When this byte = 01h, the information “Extended ATQB supported” is transmitted to the
ISO14443-B contactless card.
Allowed bit rates
This byte defines the list of bit rates allowed for the contactless interface to perform a PPS
(ISO14443-A card) or an ATTRIB command (ISO14443-B card).
The reader will select the highest allowed bit rate that is also supported by the card.
A PPS will be executed only if the ISO14443-A card is compliant to ISO level 4 and if the
selected bit rate is higher than 106 kbps.
