USB to serial - how it works

If you want to connect an older technical device with a serial port to your computer, you need a USB to serial adapter. We'll show you how the transfer works.

Adapter: transfer data from USB to serial

• Older cameras, modems and ISDN telephones sometimes still have a serial connection. You need an adapter to connect to the PC.
• You can find several of these types at Amazon. The following adapter from CSL costs around 7.50 euros, but does not require any cables. With cable, you pay around 10 euros for the following Manhattan adapter.
• Note that such adapters only connect the serial device to the PC. The reverse transfer from the PC to the device is not possible.
