Sony FCB camera block
A learning task that combines practice and understanding was arranged for the new junior female student: based on the USB TYPE-C video capture board, it was connected to the SONY FCB-EV9520L high-definition integrated camera module to achieve image output and module control. This task aims to help her deeply understand the imaging principle of the camera, signal transmission and control logic, and master the key steps of equipment connection. Through this process, they can further deepen their understanding of the technical path of the company’s core products and have a more intuitive experience of the technical integration and service capabilities that Xuanzhan Technology, as an official authorized distributor of SONY (China) and a provider of high-definition video secondary development solutions, possesses.
The girl quickly got into the mood and immediately found the products and accessories she needed
SONY FCB-EV9520L camera module
2. USB TYPE-C video capture board
3. LVDS coaxial line
4. 2-pin power cord
5. DC12V 1A power adapter
6. USB TYPE-A to TYPE-C cables
The USB TYPE-C video capture board is compatible with the SONY FCB-EV9520L high-definition integrated camera module product accessory
Then I quickly browsed through the operation manual. The SONY FCB-EV9520L can be directly connected to a computer to output images without a driver. Only the serial port driver needs to be installed. Can’t you just download a serial port driver from your office computer and install it to debug?
So easy!
The connection steps are also simple:
Step 1: Connect one end of the LVDS coaxial cable to the SONY FCB-EV9520L movement. The gold fingers must be facing up, the gold fingers must be facing up, the gold fingers must be facing up – important things are said three times.
Step 2: Connect the other end of the LVDS coaxial cable to the USB TYPE-C video capture board;
Step 3: Connect the TYPE-C end of the USB cable to the USB TYPE-C video capture board, and connect the TYPE-A end to the computer.
Step 4: Connect the 2-pin power cord to the USB TYPE-C video capture board and the other end to the power adapter.
Step 5: Finally, connect the power adapter to the power supply.

After a series of operations, the girl confidently showed it to me and murmured, “Look, the image is out. I never thought I was quite smart and could master it without any teacher.”
I said, “You zoom in to the maximum 30x zoom and see the effect.”
I had just finished speaking when I heard the girl screaming, “What’s going on? Why is the zoom progress bar pulled all the way down and the picture doesn’t move at all?”
The girl checked it carefully again. The hardware was confirmed to be fine because it can now output images. The USB cable can realize the serial port control signal, and the serial port driver has also been installed. So where is the problem?
I asked her to open the device manager to check if the serial port could be recognized normally.
“Strange, why isn’t there a COM3?” she looked puzzled. I bent down to look at her screen and she said she had installed the driver.
It suddenly occurred to me that in addition to the USB TYPE-C video capture board, our company also has another USB3.0 encoded acquisition module. These two acquisition modules are quite similar, except that the former uses a domestic integrated chip while the latter uses an imported chip. Therefore, it is natural that the serial port drivers are different.
I told my junior sister about the above situation and then asked her to take a look at the model of the main control chip on this USB TYPE-C video capture board.
She nodded in sudden realization. After a while, she said, “CH340N, is that the model?” ”
Yes, then you go and find the driver of this model and install it.
After the girl followed my instructions and opened the device manager again, the COM3 port indeed came out
“Turns out even smart people can be fooled by such a small detail,” she said with a sheepishly smile. But her fingers nimbly opened the serial port debugging software, set the port to “COM3”, slowly pulled the zoom progress bar, and then quickly repeated it back and forth a few times. The picture on the computer remained clear all the time. The little junior sister couldn’t help exclaiming, “I knew SONY’s movement module auto-focusing was relatively fast, but I never expected it to focus this fast. It’s really beyond my expectations.”
“That’s what makes it so amazing,” I explained, pointing at the screen. “SONY’s autofocus algorithm can calculate the depth of field changes in real time. Combined with the high-speed servo motor, it can instantly lock the focus when zooming.” ” She nodded, a glimmer of understanding flashing in her eyes.
After my guidance, my junior sister was naturally full of confidence. She found another USB3.0 video capture board and did another test. This time, she installed the FT232 serial port driver, and everything went smoothly. The zoom was still very smooth.
It seems that she is really quite smart.
They were also very enthusiastic. After the test, they insisted on dragging me to have a meal and said that if I didn’t go, they would prepare it and bring it to the company for me tomorrow.
Do you think it’s better for me to have dinner with her alone or for her to bring her to the company tomorrow?
