The 8x1 control panels can either be used as local or remote control panels. When used as a remote control panel the cradle assembly, model CR100, with built in 115V/230V input power supply and Ethernet interface should be ordered separately. The simple to install coax based 10Base2 Ethernet network can support up to 32 panels and 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 CP811A and CP811B panels, as illustrated use a common set of switches for both audio and video (AFV). The CP811 panels can be used with any INNOVATION Series 8-input router. When used as a remote panel a DIP switch in the remote panel cradle selects the output that is controlled by that single bus panel.
