• ISO 14443 Type B PICCs Only = {

Hints:
1. It is recommended to specific the PICC types in the application so as to speed up the card
detection process.
9. Auto PPS for the PICC Interface (Communication Speed Change)
Whenever a PICC is recognized, the reader will try to change the communication speed between
the PCD and PICC defined by the Maximum Connection Speed. If the card does not support the
proposed connection speed, the reader will try to connect the card with a slower speed setting.

• Set Connection Speed = {
E0 00 00 24 02 “Max Tx Speed” “Max Rx Speed”
}
<Max Tx Speed> & <Current Tx Speed> or <Max Rx Speed> & <Current Rx Speed>
106k bps = 00
212k bps = 01
424k bps = 02 #default setting
848k bps = 03

E0 00 00 24 00
};
Response = {
E1 00 00 00 04 “Max Tx Speed” “Current Tx Speed” “Max Rx Speed”
“Current Rx Speed”
}
Hints:
1. Normally, the application should know the maximum connection speed of the PICCs being used.
#The environment also affects the maximum achievable speed. The reader just uses the proposed
communication speed to talk with the PICC. The PICC will become inaccessible if the PICC or
environment does not meet the requirement of the proposed communication speed.
2. The reader supports different speed between sending and receiving.

10. Antenna Field ON/OFF for the PICC Interface
This command is used for turning on/off the antenna field.
• Antenna Field ON APDU Command = {
E0 00 00 25 01 01
}
• Antenna Field OFF APDU Command = {
E0 00 00 25 01 00
}
• Read the existing status APDU Command = {
E0 00 00 25 00
};
• APDU Response = {
E1 00 00 00 01 “Status”
}
Hints:
1. Make sure the Auto PICC Polling is disabled first before turning off the antenna field.
