DBP is a four-channel/four-button wired beltpack that runs on PoE+ (Power over Ethernet 802.3af and 802.3at) and connects using OMNEO IP technology. Its unique hybrid design supports both digital partyline and matrix keypanel modes: for use as a digital partyline device, DBP connects to an OMS; for use as a portable keypanel, including functionality like point-to-point communication, DBP can be connected to any RTS digital/IP matrix product using OMNEO including OMI cards in ADAM/ADAM-M frames or OMNEO ports on ODIN frames. DBP automatically selects the correct mode of operation (digital partyline/OMS or keypanel/matrix) when connected and switched on.DBPs PoE-driven design gives it an unmatched level of scalability and makes it easy to add new users. In and Out PoE ports (two etherCON locking RJ45 connectors) allow up to six DBP devices to be daisy-chained together from the same PoE switch port when used in partyline mode. Up to 40 DBPs can be connected to an OMS, allowing for the creation of an extensive digital partyline system all in addition to the other wired and wireless devices OMS supports. Depending on the matrix model/configuration, up to 64 DBPs can be connected to an OMI card for ADAM matrices, and up to 128 DBPs can be connected to one ODIN.Main Features:Hybird FunctionalityDaisy ChainingUser FriendlySpecifications:Power SupplyDC PoE: 802.3af / 802.3atMaximum Power Consumption: 4.0W (PoE DC Input)EnvironmentalOperating Temperature: -4 F to 113 F (-20 C to 45 C) 5% to 90% relative humidityStorage Temperature: -4 F 158 F (-20 C 70 C) 15% to 90% relative humidityDimensions: 5.51 in.
