The part number is highlighted in red. Below is an example of a serial number sticker. The serial number sticker is located on the side of the box/package, on the product, or on the first page of the installation manual. The SIIG part number can be found on the serial number sticker.
![]() When you are in the field, your computer won’t have an Internet connection to automatically download and install the driver.If the driver for your adapter is not automatically installed or cannot be installed from a CD, you will need to identify the chip in your cable and locate the driver on the Internet. (The older cables were silver in color and did not have a driver available for Windows beyond version 7.)Tip: Test your USB adapters in the office with your field computer. We chose this cable because it uses a chip that has a certified driver available on Windows Update. 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.For USB to RS-232 chips, there are two primary manufacturers: Prolific and FTDI. Embed a video in powerpoint for macIn the Properties dialog box, select the Details tab. In the drop-down menu that opens, select Properties. In the Windows Device Manager, right-click your device from the list. You can also identify a cable’s chip from the Windows Device Manager by following these steps: ![]() A poorly constructed cable could have components that fail in a short period of time—perhaps even by the time you receive the cable.I have seen several cases where old cables could no longer handle 115200 baud, but the cables still worked on low baud rates. Higher-quality, industrial models should last longer, but they wear out over time—just like any field tool. As much as we all wish that everything was as reliable as the CR1000, all adapter cables eventually fail.Although there are two primary companies that manufacture USB to RS-232 adapter chips, there are many cable manufacturers who offer varying levels of cable quality. Unfortunately, latency makes a noticeable difference when you download large amounts of data or upload a new operating system.The driver for FTDI chips allows you to lower the latency time on packets. The packetized communication introduced some latency (data transfer time) that wasn’t present with built-in RS-232 ports. Issue #3: PerformanceAs mentioned previously, USB uses a shared data bus with packetized communication. Lost time in the field can be a lot more costly than the purchase price of a second cable. ![]() Siig Usb To Serial Free To ShareWindows also claims that it finds no better driver than the one currently installed when doing a driver search, even after installing the manufacturer drivers.So what do I do? How do I get the adapter to be recognized correctly?What I don't understand, is that it worked fine, then all of a sudden started to detect it as a workable "USB Composite Device". It simply refuses to recognize the adapter as a USB to Serial device anymore and keeps on detecting it as a "USB Composite" device as soon as you plug it in after uninstalling it and restarting Windows. Uninstalling it and reinstalling it doesn't help.I get the same result on another computer also running Windows 10. It keeps on detecting it is a " USB Composite" device, even after installing the correct Windows drivers downloaded directly from the manufacturer's website. Feel free to share any USB to RS-232 issues that you have encountered by posting a comment below.I have an issue where my prolific USB to Serial adapter stopped being detected as 'n "Ports (Com & LPT)" device.
