The IEDA524-H digital microphone station is a 4-button device for initiating audio or visual announcements, messages, and pages with the GLOBALCOM and vACS Series Announcement Control Systems.It is a network appliance with a unique IP address that simplifies installation and configuration.The IEDA524-H features four zone group selection buttons plus a push-to-talk button located on the hand-held microphone.Just like IEDs other digital microphone stations, this uses a single Ethernet interface for audio and control data.This station is fully compatible with IEEE 802.3af standard for Power over Ethernet (PoE), allowing the IEDA524-H to be powered directly from any standard off-the-shelf PoE switch.The processing power for this comes from the onboard 32-bit processor. This powerful processor manages the input buttons, Ethernet interface, audio signal processing,and self-test diagnostics.This, and all IED LAN-based GLOBALCOM components, are designed to maximize the benefits of a standard 100 Mbps Ethernet LAN based network, using off-the-shelf switches and structured CAT5e or better cabling. The 524 Digital Microphone Station utilizes CobraNet technology.Live audio on the data network is time sensitive and requires minimal latency through the network to ensure uninterrupted audio. The IEDA524-H digital microphone station and CobraNet operate on Layer 2 (MAC Layer) of the OSI Model. This traffic will not operate on a Layer 3 Router or above. VLANs (Virtual Local Area Networks) may be required for managing traffic as well as Quality of Service (QoS) and Prioritization configuration of network switches. All connections to this digital microphone station must be full duplex 100 Mbps Ethernet auto-negotiation.
