Portāls IrDA vai IR ports ir optiskā sakaru līnija, kas datu pārraidei izmanto infrasarkano gaismas viļņu diapazonu. Infrasarkanais ports bija ļoti populārs un tika izmantots dažādu ierīču vadībai. Visbiežāk to uzstādīja televizoru un gaisa kondicionieru tālvadības pultīs. Tagad to var atrast daudzos viedtālruņos. Kādam nolūkam tas ir paredzēts?
The IR port, installed in the phone, controls household appliances. It can be a TV, a fan, a smart console, a projector, and even a camera. In general, all devices support communication through the IR port. On Xiaomi smartphones, there is a special application called “Mi Remote” or Mi Remote. It can be used to control equipment from different manufacturers. For example, to add a virtual remote from the TV, follow these steps:
- Click on the ” +” icon in the screen’s upper left corner.
- Select “TV”.
- Norādiet televizora ražotāju.
- Virziet viedtālruni uz televizoru un izpildiet ekrānā redzamos norādījumus. Tas ir, mēģiniet palielināt skaļumu vai mainīt kanālu.
IR ports are beginning to disappear in technology, as they have been replaced by faster data transfer technologies such as Bluetooth and Wi-Fi. Smartphones are equipped with an IrDA SIR port with a maximum transmission rate of 115.2 Kbps. By today’s standards, this is a very low value, but it is sufficient for controlling technology.
