The 16x1A and B control panels can either be used in local or remote applications. When used in remote applications the optional control panel cradle assembly, CR100, with built in 115V/230V input power supply and Ethernet interface should be ordered. The simple to install coax based 10Base2 Ethernet network can support up to 32 panels with a total cable length of 300 feet. For longer distances and or more panels, standard Ethernet LAN 'Hub' units can be used to expand the panel network to 256 panels. The CP161A and CP161B panels, as illustrated, use a common set of switches for both video and audio. The CP161 panels can be used either with the 16x1 routers or as single bus control panels on any INNOVATION Series 16-input router. When used as a remote panel, a DIP switch in the remote panel cradle selects the output that is to be controlled by each single bus panel.
