| Advantech Launches Ethernet Switch with Multi-Mode ST Fiber Port The eAutomation Group of Advantech introduces the ADAM-6521ST, an industrial switch with four 10/100 Mbps Ethernet ports and one multi-mode ST type fiber optic port. The fiber optic port eliminates noise interference and allows transmission distances of up to 2 km. The ADAM-6521ST supports a wide voltage range of +10 ~ 30 Vdc for power input, 3.000 Vdc power surge protection (EFT), and 4, 000 Vdc ESD protection on the RJ-45 Ethernet ports. A wide operating temperature range from -10 to 65° C (14 ~ 149° F) makes it functional in harsh operating environments. Each port has a pair of LEDs that indicate link status and transmission speed. This function informs users of any collisions, link status, power failure, and data receipts for immediate on-site diagnostics. Other features include: full/half duplex flow control, integrated loop-up engine, MDI/MDI-X auto crossover, broadcast storm protection, and flexible DIN rail, panel, and stackable mounting. write your comments about the article :: © 2006 Networking News :: home page |
