1.3 Indicator lights
Red light: When USB is connected, the 3.3V power indicator lights up.
Emerald green light: After the USB driver configuration is completed, the emerald green light lights up.
Normal: It can only be used when both indicators are on.
1.4 Wiring instructions
A0, B0: Serial port 0
A1, B1: Serial port 1
. . . . . .
A7, B7: Serial port 7

It should be noted that the serial ports generated on the computer are not arranged in order, but in an irregular order.
Of course, you can take some time to enter the device manager, modify it manually, and arrange it in order.
When I used it for the first time, I thought COM41 corresponded to A0 and B0, but it is not. It is possible that COM41 corresponds to A6 and B6.

The YR-6038 USB to 4 ORS485+4 OTTL module is a high-performance and highly reliable serial port expansion device that uses a Type-C interface without the need for additional external power supply. This device supports the simultaneous connection of 4 RS485 serial devices and 4 TTL serial devices, and has excellent data transmission and communication capabilities to meet complex application requirements.
