MIFARE & ISO14443AB & ISO15693 & ISO18000 & ISO7816 IC Card Module www.quio-rfid.de

ISO14443A T=CL card could be detected when the automatic detecting cards function is open. If

you need to operate the card, you need to send RATS command (0x30) to the module firstly. After the

module got successful response from the CPU card, then the automatic detecting cards function will

be closed automatically, please notice the information above.

Automatic detecting cards functions won't report card detected while multi same type cards are in

the field. The card data may be erroneous, if multi cards are in the electric field. And also multi cards

operation will be forced to close when the automatic detecting cards function is open.

2.3 Automatically detecting card and outputing the card UID

Users could set automatic detecting card and output the card UID. Under this mode, the card's

serial number could be output from UART or RS232C ports when swiping the card. The supported RF

protocols are ISO14443A and ISO15693. The card output method could be single time or continuously

until the card is moved away from the RF antenna field.The output format could be HEX or ASCII. In

ASCII, it can only output UID; HEX output format is according to 0x20 and 0x5C commands return

format.

When entering into automatically detecting card mode, the read/write card could not be operated

because the card will enter into halt status once when the card is detected. If need to read/write card,

automatically output the card UID function must be shut temporarily via 0x11 command and then go

on with the read/write card operations. For the temporarily setting, you could refer to "Module

working mode set".

This function couldn't work in I²C, USB and SPI interfaces. Once received the command from

I²C, USB or SPI interfaces, the “Automatically detecting card and outputing the card SNR" will be

prohibited.

2.4 Module Idle Status

This function design is aim to get low power consumption of the module. It isn't suitable for USB

interface. In idle mode, the module of RF output will turn OFF, so the power consumption will reduce

to be about 3mA. Sending the next following command to module will wake up the module, and then

the RF output will be ON. Please refer to "Set Module idle".

2.5 Module Disable Mode

Some of the QM-ABCM7 modules have CE pins. When CE pin is in low level, the module is

working. But if CE pin is in high level, the module will enter into disable mode, so the power

consumption will reduce to about 30 to 100uA (depending on the RF chip, RC522/RC523 is lower

consumption). Letting the CE pin be in low level again, the module will be woken up. The waking up

time is about 50ms.
