The truth about USB to Serial RS232 Adapters
Most new electronic devices can connect and communicate with a computer using a cable USB, however many devices still use the older type of communication protocol called Serial RS232 and RS485. To connect devices with a RS232/RS485 serial port adapter cable needs a adapter called USB to RS232 or USB to RS485 adapter, depending on whether the device protocol is by RS232 or RS485 protocol.
USB to RS232/RS485 Serial Adapter often used to connect devices such as GPS navigation units, sensors, meters, recorders, cameras, printers and other standard and special devices to a personal computer.
Most people assume that these adapters are compatible with ALL operating systems and ALL, but this is far of truth.
When you invest in a USB to serial adapter that usually pay for what you get. Many websites are selling low-cost USB to serial adapter RS232 for $ 9.95. This sounds like a lot, but when you get the adapter and connect the device to your computer is very likely to be disappointed, because in most cases, the adapter does not work properly with the computer or device. The main reason for this is that low-cost adapter is a low-power processor chip cost. These chip low-cost processors have limited compatibility with most of the devices and Microsoft Windows operating system.
limited compatibility means the adapter / drivers may or may not work with his Vista / 7 computer, it all depends on particular hardware on your computer, installed Windows components and service packs, conflicting drivers or other peripheral devices, and even your processor version bios.
In general, drivers work fine with Windows 98, 2000 and XP, however when it comes to Windows Vista and Windows 7 starts to show problems.
The drivers for a low cost USB to Serial chip processor are very often poorly written software that makes the adapter unreliable and unstable and is not fully compatible with Windows 7 and other operating systems. It is therefore in many cases can do a job of low-cost adapter with Windows 7 and Vista and can be expected that some of the following error:
- Computer Freezing
- Valid DLL Debug
Computer - crash
- Driver Problems
- Unable to connect to your device
- Could not COM port
So what are we looking to find a good quality USB to RS232 serial adapter?
First, it is necessary to determine which operating system you are using the adapter. Windows 98, 2000, XP, Vista, 7, or perhaps a Mac or Linux. If you are using Windows 98, 2000, XP or Linux can be lucky to find a low cost adapter that works for you, however, if you are using Windows Vista, 7 or Mac that have to be willing to spend between $ 20 - $ 30 for an adapter good quality work with your device and Windows Vista / 7. Try to find out what the processor chip is located inside the adapter, processors chips are good FTDI, Laboratories Silicon Semiconductors Moschip or Oxford. If you find a USB to RS232 serial with any of these processor chips will most likely be compatible with the device and any version of Windows, Linux and Mac, and you will be capable of installing the drivers easily and communicate with the device.
