Retrieved 14 October However, the characteristics of the virtual COM port are not exactly the same as a real internal COM port, mainly due to data latency ; which means that if very sensitive and precise data transfer is required, the USB to serial adapter might be unreliable and not a desired solution. Historically most personal computers had a built-in D-sub serial RS port, also referred to as a COM port, which could be used for connecting the computer to most types of serial RS devices. For the computer to be able to detect and process the data signals drivers must be installed on the computer. This page was last edited on 12 December , at

USB adapter – Wikipedia

A USB adapter is a type of protocol converter which is used for converting Hamx data signals to and from other communications standards. Languages Dansk Edit links. The non-isolated version has no protection against static electricity or voltage surges, which is why this version is usually recommended for only non-critical applications and at short communication ranges.

Views Read Edit View history. This page was last edited on 12 Decemberat Since many serial devices with a RS, RS or RS port are still in use and even still produced today, the disappearance of the serial COM port from personal computers has created a need for the USB to serial adapter.

USB serial adapters can be isolated or non-isolated. However, the characteristics of the virtual COM port are not exactly the same as a real internal COM port, uama due to data latency ; which means that if very sensitive and precise data transfer is required, the USB to serial adapter might be unreliable and not a desired solution.

The primary application scenario is to enable USB based computers to access and communicate with serial devices featuring D-Sub usually DB9 or DB25 connectors or screw terminals, where security of the data transmission is not generally an issue.
