Claim: There's no need for a VHS recorder to be connected to an ArVid ISA board via a video cable, all it needs is a remote control emulator using an LED for it to operate.
Evidence: ArVid (Archiver on Video) (Russian: АрВид, Архиватор на Видео) is a data backup solution using a VHS tape as a storage medium. A VHS recorder unit should be connected to an ArVid ISA board by a composite video cable. 
Unit operation is controlled by a remote control emulator using an LED.
