• Read DASH cable
• Simulated DASH
• Analog APPLE 2.4A

10.0.1Cable resistance detection

FNB58 uses the differential pressure method to measure the internal resistance of the cable, which needs to be used with a constant current load. Click the middle button: use the current voltage and current value as the reference value.

Measurement steps

1. Connection method: charger + FNB58 + constant current load (the current is adjusted to about 0.5-1A), press the middle button to record the reference value.

2. Connection method: charger + cable + FNB58 + constant current load (the current should be adjusted to about 0.5-1A, which should be similar to the current when the reference value was recorded), the system automatically calculates the internal resistance of the cable.

10.0.2 PD Listener

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 below.

When the PD charger cannot be powered,Because the C-C cablehas only one-sided CC,And the 2 CCs are not connected,So you can flip one of the C-C cable connectors,Solve the problem.

The figure below,The charger is a 65W PD charging head,The current PD appliance chooses the second gear,Trigger the target voltage 9V,Maximum current 3A.

Note：

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

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

10.0.3 PD Converter

• This function is used for only QC2.0 charger, But want to supply power to PD appliances.
• Before use, Switch the PD communication switch to ON, Then enter the PD protocol conversion mode,after entering,Plug in PD appliances, You can performPD fast charge.
• In this mode,C1ick the middle button and use the left and right buttons to change the maximum power of packets sent by the PD.When changing power，Becareful not to exceed the charger power to avoid unnecessary damage. After changing the power， you must click the middle button to confirm.
• Set 5v when no device is connected,Avoid high-voltage damage to mobile phones that do not support high-voltage when plugged in.
• QC2.0 only B type charger supports 20v trigger, So when the PD appliance requests 20V voltage, The tester will detect whether the charger successfully triggers QC2.0-20V,If it does not reach 20V, The tester will cancel the 20V gear,And resend the Caps broadcast.

10.0.4 USB-C-E-Marker

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 the USB-C electronic label,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 the output 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.

10.0.5 Read DASH cable

Enter this function,Plug in the DASH cable,You can read the chip-related data,As shown below

10.0.6 Soft 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.

10.0.7 Soft APPLE 2.4A accelerator

When the Apple device detects that the charging head D+ and D- are2.7V,To charge at 5V-2.4A,This function sets D+ and D- to 2.7V.
