FAQ:

Q: What’s the difference between DB9 and RS-232?

A: RS-232 is a signalling standard, and DB9 is a connector standard. Most cables that are intended to carry RS-232 signals, have DB9 connectors — but some RS-232 cables have different connectors, and some cables for other signals have DB9 connectors. The Empeg cable is suitable for RS-232 (and has DB9 connectors).

Q: What is an USB Ethernet adapter?

A: A USB to Ethernet adapter is a device that is capable of connecting a USB port to an Ethernet cable. USB to Ethernet adapters allow users to connect multiple devices together via an Ethernet cable rather than using a USB cable, which is generally shorter and less reliable.

Q: What is an USB serial adapter?

A: A USB to serial adapter, also referred to as a USB serial converter or RS232 adapter is a small electronic device which can convert a signal to RS232 data signals.RS232 is the type of signal which is in many older PCs and is referred to as a serial COM port.

Q: What is a serial port adapter?

A: Usually a single port USB to serial adapter is powered by the USB port, even many four port converters are powered by the USB port. This is the most convenient way because it does not require any additional power cables. However, most adapters with more than four serial ports are powered by an external power supply.
