PD protocol trigger

Take the picture as an example. The picture shows a charger sending a message with a total of 6 gears, among which gears 1, 2, 3, 4, and 5 are fixed voltage gears, and gear 6 is adjustable voltage gear (PPS).
When the dot on the left is on Gear, you can switch the gear by pressing the left and right keys. When the gear is switched to the PPS gear, you can switch the step voltage by clicking the middle button. After selecting the step voltage, press the left and right keys (left Decrease right plus), decrease/increase the voltage.

Charging tool

On the (6.0.3) fast charge recognition page, long-press the right button to enter the charging tool menu. The functions are:

1. PD listener.
2. Read the E-Marker cable.
3. wire resistance measurement.
4. Apple 2.4A acceleration.

PD Listener
When using a PD monitor, use a power supply not greater than 16V (usually 5V) and a Micro-USB cable to connect to the PC connection terminal, provide external power.
When the connection is normal and the PD protocol triggered by the PD consumer is captured, the page is shown as follows.

In the figure above, the charger is a 105W PD charging head. The current PD consumer selects the 5th gear and triggers the target voltage of 20V,the maximum current is 5A.

• Click the middle button to switch to the “View Detailed Communication Process” page, as shown in the figure above.

• In the left column, you can select the message to be viewed by the left/key, such as:

• Now select the message with 0x1882 REQ <-. It 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, which means that 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, 6 gears in this example, request one of the gears) ). <- Indicates the direction of data transmission, which means that
  this message is sent to the PD charging head by the PD consumer.

• The right column 3304B12C (hexadecimal) contains information such as voltage
  and current when sending a request message.

• In addition, in this interface, long press the left button to clear the data buffer.

• Long press the right button to quickly browse the messages.

Note:

1. Turn on the setting menu->trigger->mask PD CRC, 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.

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 an E-Marker chip, the packet from the PD charging head cannot exceed 3A current, and only the E-Marker cable can be used to trigger the PD According to the agreement, the current can exceed 3A.
When using the PD monitor, please use the PC communication port for power supply.
After entering this function, insert the cable from the Type-C female socket to read the message, as shown in the figure below.

Click OK to switch to the figure below.

The above two pictures, one picture is the parsed data, and the second picture is the original data. Users can consult the PD protocol related materials and make comparisons by themselves.

Wire resistance measurement page

Description
C1 uses the differential pressure method to measure the internal resistance of the cable, which needs to be used with a constant current load.

Instructions
Click the OK button: use the current voltage and current value as the reference value.

Measurement procedure

1. Connection method: charger + C1 + constant current load (the current is adjusted to about 0.5-1A), and record the reference value.
2. Connection method: charger + cable + C1 + constant current load (the current is adjusted to about 0.5-1A, and it needs to be followed
   The current when recording the reference value is similar), the system automatically calculates the internal resistance of the cable.

Apple 2.4A acceleration

The Apple device can only charge at 5V-2.4A when it detects that the charging head D+ and D- are 2.7V. This function sets D+ and D- to 2.7V.

Upgrade firmware instructions

( NOTE: The previous FNB38 and FNB48 use the FNIRSI USB Meter upgrade tool. FNIRSI-C1 uses FNIRSI UsbMeter Computer Software to upgrade the firmware now.)

1. Open the FNIRSI UsbMeter Computer Software.
2. When the meter is off, press the “OK” button fisrt. Then connect the USB data cable to the “PC online port”.And it will display the connected, device model, and device firmware version.
3. Click “System”, In the location of the file, import the firmware version you want to upgrade.
4. Click the “Refresh icon” START to start the firmware upgrade. After the upgrade is complete, the watch will automatically restart and enter the main interface.

Frequently Asked Questions

1. Q: Why is there no response when C1 is inserted into the PD charger?
   A: The CC pull-down of C1 is off by default, and the PD charging head does not supply power when the CC pull-down is not detected. After you can connect to C1, press AND HOLD the right button, you can use the CC pull-down to open the way to make the charger work.

2. Q: Use the CC cable to connect to C1 from the TYPE-C female socket, and press the right button, why there is still no response?
   A: The CC line has only one-sided CC, and the connector can be turned over and reconnected.

3. Q: How to trigger the PD protocol?
   A: If you start by pressing the right button, after entering the PD trigger, no protocol information is displayed, you need to re-plug and enter.

4. Q: After triggering SCP or PD, and then triggering other protocols, will it restart?
   A: This is the reason for the agreement, which is normal.

5. Q: After the SCP or PD is released, if another protocol is triggered, it will restart?
   A: This is the reason for the agreement, which is normal.

6. Q: Enter the PD to monitor a black screen?
   A: Entering the PD monitor will turn off the CC pull-down, so it is recommended to use an external power supply.

7. Q: PD monitoring fails and there is no data?
   A: Switch to the page of “View detailed communication process”, and then long press the left button to clear the data buffer area, and then trigger the monitoring.
