Serial Ports are a common way to communicate with devices. The most common serial ports, as used by devices like Metex/Voltcraft multimeters, are RS-232 interfaces.


RS232-USB Converters

To operate devices having RS-232 interfaces on computers that have only USB interfaces available, RS232 to USB converters are available. Many different chipsets exist that have slightly different properties, often supporting only a subset of what common UARTs like the 8250/16550A can do. Please note that a driver for the respective operating system is required (sometimes included in the OS already, e.g. mostly for Linux).

Common chipsets are:

Manufacturer Type OS Data Bits Non-standard baud rates Max. baud rate Homepage Remarks
Prolific PL-2302x 1
Prolific Fake (PL-2302) It seems that fakes of prolific chips with limited reliability exist.1
FTDI
MOSChip (Asix)
MOSChip (Asix) 4 Ports
