The GT-MCX is a network adaptor that will allow multiple GT Series systems to be connected over a network. A typical system, when expanded, will support up to 16 entrance stations, 4 video guard stations, and 5 tenant stations. When using the GT-MCX, up to 32 GT Series systems can be connected together allowing the total capacity of the system to grow to 48 entrance stations, 96 video guard stations, and 5, tenant stations.The GT-MCX divides a large system into sections. There can be 24 tenant sections and 8 main sections. The tenant section can consist of entrance stations, video guard stations, and tenant stations. The main section can consist of entrance stations and video guard stations only. Each GT-MCX takes the place of 1 entrance station and 1 video guard station.The GT-MCX can be used to update the GT Series system from the GT Support Tool when connected to the same logical network. Updating the system could include changing tenant names and dialing numbers on both the guard and entrance stations.FEATURES Allows for network connectivity Remote programming device via network Connect systems/buildings together Expand system capacity to multiple buildings, accessible from common entrance and guard stations
