The 32x32 X-Y control panels can be used as either local or remote control panels. When used as a remote control panel the optional 2RU cradle assembly, CR200, 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 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. Operation of the X-Y panels is very straightforward. First the desired destination (output) is selected. Once the output is selected the source (input) buttons will tally and they are used to select the desired input to that destination. Outputs that have been 'locked' are indicated by the output lamp flashing when a locked destination is selected.
