Product Introduction
ADM-2813 is an industrial grade USB to RS-485/422/232/TTL optoelectronic isolation converter, which has no external power supply and is compatible with USB1.0/USB2.0 standards. It can convert USB signals from computers or industrial control computers into RS-485/422/232/TTL signals, with zero delay automatic transmission and reception conversion, automatic control of data flow direction, and plug and play functionality. Internally, the imported FT232RL chip is used as the USB signal conversion chip, and the RS-485/422/232 interface has lightning protection, surge protection, and anti-static protection, ensuring stable and reliable operation.
