Structure Explanation

NFC Usage Demo

After activating NFC function, put the NFC card close to the sensing area. If the card is successfully recognized, there will be a beep. If the card contains some information. (such as manufacturer’s information), the interface will pop up, as shown in the figure below. If the card has been recognized, tahe interface will not always pop up, but there will be a beep.

System Root Switch Usage Guide

1. Refer to the following figure to enter the Root authority (on/off) function setting interface.
2.  The root switch setting interface is as follows. In the figure, “1” is the Root permission (on/off) switcher. In the figure, “2” is the dialog for password modify function.
3. Please enter the password (The initial password is qwertyuiop).
4. Dialog for modifying the password required for the root permission (on/off) status

Note! If the device is restored to the factory setting, the state of the root access will be reset to off, and the password will be restored to the initial password.

2. Power off: When the device is turned on, in non-sleep state, long press the power button for 2s, the optional menu will pop up. Select “Power off” to shut down the device, and then shut down the screen.
3. Restart: When the device is turned on, in non-sleep state, long press the power button for 2s, the optional menu will pop up. Select “Restart” to restart the device, then the device will be shut down and restarted.
4. Automatic sleep: Sleep time can be set in Setting; Press short to enter hibernation mode.
5. Device Wake up: Short press the power button to wake up the sleeping device.
6. The correct operation of the power button will help to ensure the stability of the system, and the color of the indicator light indicates the device status, as shown in the following table:

Instructions SIM Card &TF Card
Before installing the SIM card, please turn off the device in advance. And insert the required card into the machine in the direction indicated in the figure below. Finally, press the power button to start the machine.
Note! TF card support hot plugging, SIM card doesn’t support.

Installing & Replacing The Battery

1. Rechargeable Battery for optional
   Due to transportation reasons, the battery will be partially depleted when you receive the device. And charging for the first time, be sure to fully charge the battery. Please keep the DC in a charged state when working. DC input power can be used prior to the internal battery when using the device so that the batteries can be stored after being fully charged. This excellent design is very helpful to extend the service life of the equipment battery and ensure safe use.

2. Replacing the Battery
   The tablet battery is installed in a removable way, which greatly facilitates the user’s use of disassembly and installation.
   ( Note: Please shut down before removing the battery.)

3. Installing the battery
   To install a new battery, orient the new battery so that the contact pins are aligned correctly, and assemble the battery cover and secure the retaining screws by using a screwdriver with flat head. Note! In order to ensure the life and performance of the battery, if your tablet has been stored in the warehouse for more than three months, it is suggested to charge the battery every three months.

ACC Setting Path
ACC settings are located in ACC options under Android OS Menu Settings. Automatically control screen brightening, hibernation and shutdown after ACC is disconnected. Please refer to below figure.

Click go to Settings and select “ACC Settings” as shown.

After enter the ACC setting interface, the following options are displayed:

• Mark 1: The main switch of ACC setting, the current ACC function is off.
• Mark 2: The switch of close screen function controlled by ACC.
• Mark 3: Set the screen-off delay time after the ACC is powered off, click to enter the delay setting interface.
• Mark 4: Set the delay time you need, the current delay is 1 s.
• Mark 5: The switch of Trigger to shut down function by ACC outage. Current display is: when the ACC is powered off, the tablet will automatically shut down.
• Mark 6: Set the tablet shutdown delay time.
• Mark 7: You can set the delay time you need, the current delay shown in the figure is 300s

GPIO Setting

GPIO Tail Lines Instruction
Regarding the definition diagram of GPIO interface, please see the details in Chapter three “Extension Cable Define”.

GPIO Typical Connection
The following figure is a typical connection method of GPIO. In order to ensure communicate normally, please connect the GPIO interface of PC-7108 as shown in the following figure.

GPIO Interface

Double-click“ ” to enter the GPIO interface:

• Name: GPIO pin number.
• Direction: GPIO state. You can choose GPIO as the input state or output state. As shown in figure “1”.
• State: HIGH of high level, LOW of low level
• Operation: Read whether the current mode is high or low, displayed in the status bar.
• READ_ALL: GPIO is the state of the level at input.
• SET_ALL_LOW: GPIO is the state of the level at output.

Note!

1. Each port of GPIO1~8 can be set as as an output or input port separately by GPIO APP or other software measures.
   GPIO must not be directly connected to the power supply without any current limitation if it has been set as an output port, otherwise the interface will be damaged by overcurrent.

2. When any port of GPIO1~8 is set as an output port and is connected with a inductive load, an diode of at least one ampere rating current is required to parallel
   connected with the external load.

3. GPIO 0~7 on the software interface correspond to GOIP1~8 in the interface diagram.
