1 Introduction

This file describes “working modes” and “communication protocol” of QM-ABCM7 series IC

card module in details. It's suitable for the programmers who are using Series QM-ABCM7 RFID

module to do the development.

If you have any question during the programming, please feel free to contact our technical

support via kontakt@quio-rfid.de.

2 Function

QM-ABCM7 series IC card module is high efficient product. We have built in a lot of advanced

functions. However, if you are still not satisfied with these functions, please contact us.

2.1 Basic Mode

QM-ABCM7 is a slave device; the "ask & answer" is the basic working mode loop. That means if

QM-ABCM7 receives a command from master machine, it will execute the command and answer to

the master machine. This is a command cycle. A new command won't be accepted while the module is

executing a command. So when you develop the application program, you MUST be sure the last

command cycle is finished in order to send the next command.

2.2 Automatically Detecting Card

QM-ABCM7 supports automatic detecting cards that are based on ISO14443A and ISO15693.

When the automatic detecting cards function is open, QM-ABCM7 will continuously send searching

card commands. Once the card enters into the effective electrical field, the ICC pin will show low

level. In this situation, you could directly do operation to the card. If the automatic detecting function

is close, when you want to do operation to the card, you need to send searching card command firstly.

The default automatic detecting cards function could be set via 0x1D command. This setting is

saved in FLASH, which means that this setting will be effective on next power on. While module is

working, the automatic detecting cards function could be temporarily open or closed via 0x11

command. However, this setting won't be saved. So after turning on the power again, it will be back to

the default setting.

If the module operate card mode (via 0x70 command) is set to ISO15693, then QM-ABCM7 will

just only auto detect ISO15693 cards. If the module operate card mode (via 0x70 command) is set to

ISO14443A, then QM-ABCM7 will just only detect ISO14443A cards. While automatic detecting

card is open, any other type of card operation command will change the module operate card mode,

and results in the fail of the automatic detecting.

Automatic detecting cards function support ISO15693 cards.

Automatic detecting cards function support MIFARE 1K/4K and MIFARE Ultra Light cards.
