Data converters are small digital devices that convert analog to digital data and vice versa. Also called analog to digital converters (ADC) and digital to analog converters (DAC), these devices create an interface between circuit types. They negate the need to replace hardware, including internal PC components, and connect older devices to modern equipment. Converters are available as simple connections that fit inside hardware and leads that connect separate devices. Other types of connectors include HDMI to VGA and USB to serial. Both of these devices convert digital to analog or analog to digital.
Modern computers use USB ports to connect hardware devices. USB to serial converters connect old keyboards and modems with serial connectors to a computer port or a USB hub, So you don't have to spend money upgrading old hardware that remains otherwise viable. Older printers also rely on serial connections. These devices require the installation of driver software that converts the serial signal to a USB signal. Ensure that the device drivers are compatible with your PC before purchase.
Other USB cables include those that convert between USB-A, USB-B, and USB-C. Mobile phones and media devices commonly use these standards for data transfer and uploading and downloading information. Mobile phone data converters enable the transmission of information between mobile phones, making it easier when you upgrade to a new device.
TVs, satellite boxes, and other media devices rely on high definition multimedia interface (HDMI) technology, which replaced its predecessor, VGA. HDMI cables also connect monitors to modern computers. If your monitor has a VGA port, you don't need to throw it out. Instead, you can use an HDMI to VGA converter. These devices connect to the HDMI socket of a PC via a VGA cable. You can also buy connectors for HDMI monitors to connect to older VGA PC ports.
When shopping for data converters, you need to know the gender of each connection. Male connections plug into a female connector, and female options accept a male socket. When connecting a monitor to a PC, for example, the HDMI cable has a male connection and the PC port is female. Therefore, if you are connecting an HDMI monitor lead to a VGA PC, you would need a connector with a female HDMI input and male VGA output.
Analog connections have replaced digital in a lot of instances. HDMI has replaced VGA, and USB has replaced serial, offering more secure signals with low bandwidth and higher data transfer speeds. Digital to analog converters let you continue using an old PC, saving the hassle and investment of upgrading, while still taking advantage of modern technology.
