Product Description
TOA N-8000RS Sub Station Interface Unit
The N-8000RS Substation Interface Unit uses packet audio technology to permit connection of up to 16 RS-1xx series call switches or door stations. Call switches and door stations use the same shielded twisted pair wiring. Each port provides 1W @25V to a door station, or 25V loudspeaker attached to a call switch. Each N-8000RS supports 2 voice links. The N-8000RS requires an IP master station, or connection to a 2-wire or 4-wire Exchange with at least one master station on the exchange.
The latest software version is 4.2.2 (update:2020/6/18), with previous versions 4.2.0(update:2015/04/03), 4.10(update:2014/11/13),and 1.41(update:2008/10/06). The Maintenance Software(Ver.1.2.0) is used to monitor or maintain equipment within the system(upload:2015/04/03).
