4.4 Keypad connectionsThe keypad can be connected directly to amultifunction display’s (MFDs) network connectoror via a network switch. Multiple keypads can beconnected to a system. Each keypad can be used tocontrol multiple MFDs. If the network is not providingPower over Ethernet (PoE) then the keypad must bepowered using the Alternate power connector.Note: When connecting the keypad to a gS SeriesMFD, ensure that the supplied RayNet cable isconnected with the suppression ferrite fitted on theend of the cable closest to the MFD.Direct MFD connection with PoE1. gS Series (MFD providing PoE)2.
