Because off-brand chips with poor drivers are unreliable, Campbell Scientific recommends and currently sells a cable using an FTDI chip ( part number 17394). The driver must correspond to the chip inside the cable-not to the manufacturer of the cable.ДЇor USB to RS-232 chips, there are two primary manufacturers: Prolific and FTDI. The most common problem that our customers encounter with a USB to RS-232 adapter is getting the proper driver installed. For example, there are three types of problems that you may encounter when using a USB to RS-232 adapter: While USB to RS-232 adapters perform a necessary function, they do have some limitations. Therefore, to connect an RS-232 device (such as a CR1000) to a computer, you need to use a USB to RS-232 adapter, such as the 17394 converter. With the widespread adoption of USB, most computers sold now do not have an RS-232 port.

The software driver sits between the hardware and the computer program you are using, and it must be installed and working correctly. To handle the packets and move data in and out of the program accessing the USB device, a software driver is needed. Data is wrapped up and transferred in packets. USB devices have high throughput, but they use a shared data bus.

The USB provided smaller connectors and more data throughput than the serial and parallel interfaces it replaced. In 1996, the Universal Serial Bus (USB) standard was introduced as a replacement for the serial connector and other connector types that were typically found on the back of computers. Data practically flowed directly to and from the software that was accessing the serial port.

Built-in RS-232 ports featured direct mapping to memory and worked at a high priority. The connector was reduced from a 25-pin connector to a 9-pin connector, but RS-232 ports remained present on every computer for many years. Apart from the parallel port, it was the primary means to connect an external device. In the old days of personal computers, one of the primary connections available was the RS-232 serial port. In this article, IвЂ™ll briefly discuss the origin of these issues and provide you with some suggestions for successfully handling them. Our customers frequently encounter issues with these adapters. Recently I got a ESS32-CAM card and it contains the same Ch340 chip and it has worked fine even with the USB cable so I suspect that the ch340 designer released an updated design of the chip that meets the USB timing specs or maybe some aspects of the board design are adjusted to help make the timings.Д«ottom line, unless you enjoy chasing down problems you will be better off buying the more expensive ftdi or other non-Chinese designed chips.Have you had difficulty using a USB to RS-232 adapter to connect your RS-232 device to a computer? If so, you are not alone.

When I say I get it to work, all I have been able to do is install the wrap connector and get the adapter to talk to itself as verified with putty. This would also explain why sometimes it will work after installing into a different USB connector on the PC since those timings can vary as well. Consequently if a chip designer is not careful about meeting USB timing specs then there will be situations when that chip will not work. From my work experience I know that the USB timings are very critical in order to maximize performance. However, if I use an extension USB cable most of the time it fails to work. I say this because I have noticed that if I plug my Ch340 board directly into my USB port it works. Next, it is apparent that the Ch340 design does not meet USB standards in the area of critical timings. After doing that I was able to solve the install failed problem. First thing to do is run/click the uninstall button. Since my last posting I have discovered some things that may help eliminate this problem.
