Configuring the ACS1552U Reader as a UID scanner

Before configuration, we must prepare all the technical components we need for configuration. We need a computer with the Windows 10 or 11 operating system and an internet connection. The computer should have a free USB-C port or a free USB-A port. If there is a free USB-A port, we need a USB-A to USB-C adapter. Then we need the ACS1552U USB-C Reader. If we want to read the UID after configuration with the iPad, we need an adapter for the iPad. Finally, we need the reader's configuration tool.

First, we need to connect the reader to the USB-C port on the Windows computer. Now let's download the configuration tool. To do this, click on the following link (https://www.acs.com.hk/en/products/575/acr1552u-usb-nfc-reader-iv/ ) and go to Downloads in the top bar. There, we tap on Configuration Tool 34.44 KB, Version 100. A zip file will then be downloaded to our computer. After clicking on the zip file, the file manager opens. There, we tap on Extract All and select the folder to which the file should be moved. Then we click on Extract.

Now tap on the folder Keyboard Configuration Tool V100 and start the application ACR15XX Series Keyboard Configuration Tool V100.exe.

To configure the reader as a UID scanner, select the following reader in the Select Reader section: ACS ACR1552 1S CL Reader PICC 0. Then tap Connect.

Important! – If the reader is not displayed, first check that you have connected the reader correctly to your Windows computer and then click on Refresh.

In the Reader Configuration section, we can now change the input mode. There are 3 options.

• Only HID Keyboard: this option means that the reader is only recognised as a keyboard input. This means that the reader is only used for UID input. Important – if the UID is to be read via the iPad, we must select this option!

• Only CCID Reader: this is the default mode and with this option, the reader cannot be used as a UID scanner. Important information: To undo the configuration and use the UID scanner as a normal NFC reader again, you must select this option.

• HID Keyboard + CCID Reader: this option recognises the reader as a keyboard input and has the functions of a reader. This means, for example, that an NFC tag can still be written to. Important – if you also want to use the reader for other NFC functions, then select this option!

To configure the reader as a UID scanner, we select either Only HID Keyboard or HID Keyboard + CCID Reader, depending on our use case. After selecting the input mode, click on Apply. The reader can now be used as a UID scanner on any device.

Connecting to the iPad: To connect the reader directly to the iPad after configuration, we need to click Quit and connect the reader to the iPad.
