ACKSYS , Communications & Systems • 3 in 1 built-in serial interface : RS232/RS422/RS485 • Serial link up to 2 Mbps for RS422 & RS485 mode, 1 Mbps for RS232 mode • Reliable error free communication even in case of EMI/RFI pertubations • Fiber length up to 5000 m (100/140 pm fiber type), ST type connectors • Automatic RS485 line turn-around • Half-duplex & Full-duplex bidirectionnal data transmission • Activity LED for fiber and copper TxD & RxD signals, error LED in case of fiber breakdown • Wide DC power range, from +9VDC to +36VDC • Point to point mode and multipoint redundant mode (fault tolerant) • 15 KV ESD protection and HF filtering on the copper side • Robust & compact metal case, CE standards, 35 mm Din Rail mounting Introduction Using fiber optic enables to use a higher communication bandwidth while offering a total immunity against EMI/RFI interferences and an increased security as well. The optical fibre still offers other advantages : use without risk in an explosive environment, no EMC emission, no ground loops, immunity against lightning and high voltage environments, they are finally lighter, less cumbersome, inert and corrosion resistant ... Plug & Play: RD300 features a self configuration mechanism based on a CPLD component that frees you from the tiresome operation which consists in the serial parameters setup, product is «Plug & Play». RD300 features in standard a built-in system to control the fiber integrity, it reports automatically any failure with an error LED and also setups a relay contact (MOSFET) to activate any external safety device. Its small size, design features and its great adaptability make the RD300 a really universal product capable to satisfy to major needs of the industry. COMMUNICATIONS & SYSTEMS
