The CSI-200 is a bidirectional, two-channel coaxial interface which passes digital audio and control data between RTS keypanels and matrices. At 1RU high and ½RU width, the CSI-200 is compact allowing up to four coaxial channels in a standard rack space. Installation of the CSI-200 is quick and simplified with no user settings. Each of the two channels of the CSI-200 are independent and may operate in either on the keypanel or matrix side. LEDs provide the user with status information on the unit’s connections. The CSI-100 bidirectional coaxial interface is available as an option kit for KP-32 Classic.
