Video, data and contacts transmitter



The DEM-720 equipment allows to create point-to-point links for the digital transmission of video + data and contact over an optical fiber, up to distances of 25 km (50 km with receiver). Provided with a communication channel compatible with the EIA / TIA / RS-232,422 & 485 standard. Built-in alarm mode, activating the isolated contact on the receiver when the video signal or link is lost. Front LEDs for verification of power supply, links, remote / local contact and data transmission. Plug and Play design that facilitates the start-up of the installation. Digital video transmission allows longer link distances with high image quality. Rack mounting formats for 19 ”3U Chassis (PAWAL) and desktop / DIN Rail.
