Safety Precautions

• Do not connect the monitoring interface to a power supply exceeding 24V.
• Do not connect the PC connection port to a power source exceeding 16V.
• Only one pair of monitoring interfaces (one input port, one output port) can work at the same time. When there is a pair of monitoring interfaces working, it is forbidden to connect to the equipment on other monitoring interfaces. (Except the PC connection port, the PC port can be connected to an external power supply.)
• When using the fast charge trigger module, please do not connect equipment that cannot withstand high voltage to any monitoring interface.
• After using the PD trigger/monitor/conversion/read E-Marker cable function, please turn the PD communication switch in the lower right corner back to the OFF position.
• When working at high power,the temperature of the instrument rises.Please be careful to prevent burns.
• Do not charge the phone after the fast charge is triggered.The manufacturer is not responsible if the phone is damaged by doing so.

Charging tool

On the (7.0.3) fast charge identification page, long- click the right button to enter the charging tool menu. The functions are:

• PD monitor
• Read the E-Marker cable
• Apple 2.4A acceleration
• Read the DASH cable
• Analog DASH cable

【10.0.1 】 PD Listener

※The figure above,The charger is a 65W PD charging head, The curren PD appliance chooses the third gear, Trigger the target voltage 12V, Maximum current 3A.

※Click the middle button,can switch to the page of “View detailed communication process”,as shown.

• When using PD listener,Need to turn the PD communication switch to ON,And use a power supply not greater than 16V (usually 5V) and a Micro-USB cable,Connect the PC online port,Provide external power.

• Use the PD listener function, need 2 C-C cables, connect the charger and PD electrical appliances from the Type-CIN interface and Type-COUT interface respectively. When the connection is normal and the PD protocol triggered by the PD consumer is captured, the page is represented as shown. When the PD charger cannot be powered, because the C-C cable has only one-sided CC， and the 2 CCs are not connected, you can flip one of the C-C cable connectors，to solve the problem.
  Left column,You can select the message to be viewed by left/key,Such as:

• Now select the message of 410x1882REQ<-. is the message number,In this instrument, the larger the message number, the newer the message.0x1882 is the message header.REQ is the message type, Represents this is a request (Request) message,The request message (Request) is used to apply to the charging head for the gear required for charging (for example, it is 6 gears in this example,request one of them). <- indicates the direction of data transmission.It means that this message was sent by the PD consumer to the PD charging head.

• The voltage contained in the right column 0x3304B12C when sending a Request
  message,Information such as current.

• In addition,under this interface,long press the left button,the data buffer can be cleared. Long press the right button to quickly browse the messages.
  Note:

• Open the settings menu -> trigger -> block PDCRC, you can turn off the monitoring of CRC.

• For the meaning of various messages in the PD protocol, please refer to the relevant information.

【 10.0.2 】 Read E-Marker cable

• E-Marker cable refers to a cable with an E-Marker chip in the Type-C interface,If the interface does not contain E-Marker chip.The packets from the PD charging head cannot exceed 3A current,and only use the E-Marker cable to trigger the PD protocol,the current can exceed 3A.

• When using PD listener,except that the Type-C interface cannot be used for power supply,PC port, USB-A, Micro-USB interface can all be used for power supply.The PD communication switch needs to be turned ON.

• After entering this function, From any Type-C interface, plug in the cable. You can read the message,As shown below.

• Click the middle button to switch to the figure below.

The two pictures above,the picture shows the parsed data,the second picture is the original data,Users can consult the relevant information of the PD agreement by themselves,do your own comparison.

【 10.0.3 】 Read DASH cable

• Enter this function,plug in the DASH cable,you can read the chip-related data,as shown below.

【 10.0.4 】 Analog DASH cable

This function is used without DASH cable

• The USB-A head of the DASH cable will have one more data pin than the ordinary USB-A data cable.And one more chip,used to identify and start VOOC/WARP flash charge.
• If the phone normally needs to use a USB-A->Type-C DASH cable,but there is no such thread in hand,only FNB48 tester and a C-C cable,but want to trigger VOOC/WARP flash charge.At this time, the function of simulating DASH cable can be started,and
  use the C-C cable to connect to the phone, you can perform VOOC/WARP flash charging.

※Note:Since this method does not use the original data cable for charging, the charging power is largely affected by the C-C line.If the impedance of the C-C line is high,then the charging power will be reduced a lot.

【 10.0.5 】 Apple 2.4A acceleration
When the Apple device detects that the charging head D+ and D- are 2.7V,to charge at 5V-2.4A,this function sets D+ and D- to 2.7V.
