When used as an XNET networking interface the NIM-1W allows for the connection of up to 63 MXL and/or XLS Systems. On an XNET network the NIM1W also supports monitor and control functionality by Siemens products, such as NCC and Desigo CC. Output logic between MXL panels is done using CSG-M programming. CSG-M versions 6.01 and higher include options for networked MXL Systems. Each MXL System is assigned a panel number. This panel number allows interactive programming between panels using CSG-M.
