N-8500MS IP Multifunctional Master Station
N-8500MS
The N-8500MS is an IP multifunctional master station employing packet audio technology. Connecting the N-8500MS to an IP network (LAN or WAN) permits hands-free or handset conversation of high sound quality to be made between the N-8500MS and intercom stations connected to the IP Intercom Exchange, or between the N-8500MS units. Besides, the N-8500MS can be used in conjunction with the Multi Interface units through a network. The Multifunctional Master Station provides LCD display, Auto-dialer function enabling one-touch dialing, headset terminal and external speaker terminal. Power can be supplied from the PoE (Power over Ethernet) switching hub. (In this case, an AC adapter is not required.) This station can be mounted to the wall using an optional YC-280 wall mounting bracket.
