    Video Input Indicators - Next to each video input connector is a small LED that indicates the status of each link. SFP+ Inputs - (4) SFP+ slots provide inputs for SDI over coax. Each input takes a Megapixel 12G SFP+ for up to 12G SDI.

  • Page 11: Network Switch Overview

    Network Switch Overview The network switch converts between fiber and copper for the HELIOS system. The GSM4210P model which is commonly used, receives data on one 10Gb fiber LC SFP+ and has eight 1Gb Copper Ethernet ports as outputs. These network switches are usually located near the display as they provide a signal over copper directly to display panels.

  • Page 12: System Planning

    This is accomplished with media processing equipment prior to the HELIOS Processor. If the total number of pixels will not fit the input raster, the system will need to be subdivided and multiple HELIOS Processors need to be used.

  • Page 13: Connections

    Processor Connections Power - A/C power is supplied to the HELIOS Processor on a C14 style IEC connector. Next to the power input connector is a rocker switch. When power is turned ON, the system will begin to boot. After about 15 seconds the front LCD display will be lit.

  • Page 22: Creating Maps

    Creating Maps The HELIOS Processor uses a map to determine which segments of the incoming raster to consider as an ‘active pixel region’. Areas of the incoming raster that are not associated with display fixtures, are never transmitted to the system. If only two fixtures are mapped, only two fixtures worth of panel data is being transmitted.
