Built-in onboard 500ma self-recovery insurance to protect computer equipment and usb ports,
Realize the mutual conversion of USB, TTL, 232, 485 functions through the switching of physical switches. Interface standards: compatible with EIA/TIARS-232C, RS-485, TTL
◆Support system: so Windows system also supports WINCE and LINUX?? Whether it is X86 or X64, it is supported
◆Protection current: 500ma
Working temperature: -40℃～85℃, humidity: 0～95% Dimensions: 78mm×52mm×30mm? Weight: 30g Shell: high-quality plastic shell, small and light, high insulation safety factor Installation and description of the drive:
1. First, open the CP2102 driver folder in the data package and install the driver. If 32 is the system, please install CP210xVCPInstaller_x86.exe, if 64 is the system, please install CP210xVCPInstaller_x64.exe. Click the next step all the way to complete the installation. After the installation is complete, insert the six-in-one serial port module to create a virtual COM port on the PC side.
Transparent transmission, users do not need to change the protocol, support plug-and-play and hot-swappable (USB end) Built-in 500ma self-recovery insurance onboard, protect computer equipment and USB ports,
Realize the mutual conversion of USB, TTL, 232, 485 functions through the switching of physical switches. Interface standards: compatible with EIA/TIARS-232C, RS-485, TTL
◆Support system: so Windows system also supports WINCE and LINUX, both X86 and X64 are supported
Protection current: 500ma

1. First, open the CP2102 driver folder in the data package and install the driver. If 32 is the system, please install CP210xVCPInstaller_x86.exe, if 64 is the system, please install CP210xVCPInstaller_x64.exe. Click the next step all the way to complete the installation. After the installation is complete, insert the six-in-one serial port module to create a virtual COM port on the PC side. When the driver is installed successfully, insert the converter, the system will virtual a serial port (for example: COM5 can be viewed in the device manager); Note: If the virtual serial port number is greater than 7, please change it to 1-7. The port is too big Affect stability.
2. Set the com port: set the virtual serial port number to the corresponding position of the software. If it is set to the COM port of the serial port debugging software; it can be used.
Dialing mode and wiring instructions:
The pin underneath the DIP switch 1 is pin 1. From left to right, it is 1, 2-6, and the next row is 7, 8-12. The corresponding signals are as follows:
The DTR/RTS output interface is retained, and the level of these two pins can be controlled through the serial port. When downloading programs for some single-chip microcomputers, the reset can be automatically completed, such as for Arduino.MSP430 downloading programs
Functional self-closed loop test
The function of the product can be verified through the self-closed loop test. The method is as follows: USB to TTL self-closed loop:
Connect the TXD and RXD of the module with DuPont cable, then set the dialer to 10000, then insert the module into the computer, and use the serial debugging assistant to send data to see if there is a corresponding data return. If the sent data can be received, it proves that the module functions normally.
USB to 232 self-closing loop:
Connect the 232-TXD and 232-RXD of the module with DuPont cable, dial the corresponding DIP switch according to the instructions in the function selection, then insert the module into the computer, and use the serial debugging assistant to send data to see if there is a corresponding The data is returned. If the sent data can be received, it proves that the module functions normally.
USB to 485 self-closed loop test
(This mode test needs to cooperate with other 485 devices, such as two six-in-one modules) Take two six-in-one modules, turn the DIP switch to USB to 485 mode, and connect the two modules A and B with DuPont cables. Connect A to A, connect B to B, insert the module into the computer, open the two serial debugging assistants, select the serial number of the two six-in-one serial modules respectively, use one of them to send, and see if the other serial port can accept the corresponding data , If the data sent out can be received, it proves that the module is functioning normally.
