1.2.Safety instructions
Please read the following instructions carefully to prevent injury, malfunction, fire, etc.
Warning
Do not attempt to disassemble, modify or repair the AsReader yourself, otherwise it may
cause malfunction, fire or electric shock. We will not be held responsible for any problems
that may occur with the AsReader, PC, smart devices, etc. due to modifications.
If you notice any abnormalities such as smoke, abnormal odor, or strange noise coming from
the AsReader during use, stop using it immediately. Continued use may cause fire or electric
shock.
Do not drop or throw the AsReader and subject it to strong impact. It may cause damage,
fire, electric shock, or malfunction. It may also cause injury. If the AsReader is damaged by
dropping and the inside of the AsReader is exposed, do not touch the exposed part with your
hands, because there is a risk of electric shock or injury on the damaged part.
Do not allow metal or other objects to come into contact with the terminals of each connector.
Doing so may cause a large current to flow, resulting in overheating, fire, or damage to the
device.
Do not get the AsReader wet with water or any other liquid. Doing so may result in fire or
electric shock. If foreign matter or water does get inside the AsReader, unplug the power
cable immediately.
Do not use, store, or leave the AsReader in hot places (eg. by the fire, near a heater, in direct
sunlight, in a car in hot weather). It may cause rupture, malfunction, fire or injury.
Do not use the AsReader with any power supply voltage other than the specified. Doing so
may result in damage to the equipment or an accidental fire.
When constructing a system that may affect human life, such as the management of
chemicals using the AsReader, please pay close attention to redundancy and safety design
so that even if the data is incorrect, there is no possibility of affecting human life.
The AsReader is an RFID reader that uses UHF radio waves with an output power of 500
mW. Therefore, depending on the application and location of use, it may affect medical
equipment. In order to minimize this effect, the following must be strictly observed during
operation.
The AsReader operators should keep the AsReader at least 22cm (9in) from any site where
implantable medical devices are installed.

3Workingmode
◆The ASR-P35U has two working modes: HID mode and Serial mode.
⚫HID mode
HID (Human Interface Device) mode: When this product is connected to a mobile
device (or a PC) in HID mode, this product is recognized as a keyboard, and the
data read by this product is sent to the mobile device (or the PC) “as is,” displayed
as a text input tool. Therefore, there is no need to use an App that uses a dedicated
SDK. HID mode supports Android and Windows devices.
⚫Serial mode
This mode enables real-time data transfer between ASR-P35U and the App that
uses a dedicated SDK.
There are dedicated SDKs for Android and Windows.
◆How to change modes?
Switch between Serial mode and HID mode by switching Dip Switch 2’s ON/OFF
switch (see FIG. 1-3-2⑥) of the ASR-P35U.
Serial mode: 2-ON
HID mode: 2-OFF
FIG. 3-1 Change mode
If it is powered on, the mode switching is completed after two buzzes.

◆How to read RFID tags in HID mode?
When the ASR-P35U is powered on, put RFID tags close to the Antenna of the ASR-
P35U (see FIG. 1-3-1①). Press the “SCAN” Trigger Button (see FIG. 1-3-1②), and
the blue light flashes quickly. The data will be entered at the cursor on the screen of the
Android device or Windows deivce. Press the Trigger Button again to stop reading.
