DMA30N Remote Bus Network Decoding Terminal

Features

● Features a die-cast aluminum alloy chassis with an acrylic front panel. Includes standard accessories for wall-mounting. With the optional PAVA9002S accessory, 1 to 4 units can be combined into a single 1U-high rack-mounted configuration.
● Powered by the amplifier host bus at DC48V.
● Supports external DC24–48V power supply, which can serve as a backup for bus power.
● Can operate as a standalone decoding terminal when equipped with an optional DC24V power adapter.
● Device discovery, version checking, IP configuration, and firmware upgrades (for SSD212) can be performed via the networked PC client software.
● Includes one RJ45 network port with LED indicator for LAN connection. Dual RJ45 audio and data bus ports for RS485 communication with the amplifier host and transmission of analog audio to the host. Supports daisy-chaining of DMA30W remote control panels and other bus-compatible terminals. Stable transmission up to 300 meters when cascading a maximum of 3 devices per port. Maximum transmission distance of 600 meters when a single device is connected to one port. Note: Only one remote bus network decoding terminal can be connected per amplifier host bus.
● Includes one dual‑channel RCA connector supporting two line outputs.
● Compatible with MAG6000 system for network decoding and playback.
● Supports offline scheduled playback with optional or user-provided micro SD card up to 32GB.
● Supports fire alarm integration (EMC) with dry contact output and DC24V output. DC24V output requires the optional DC24V power adapter.

Introduction
Specification

The Remote Bus Network Decoding Terminal is a fully network-based, all-digital analog-to-digital signal processor operating on the TCP/IP transmission protocol. Featuring a dual-network interface redundant design, it can be deployed at any location accessible via the network. This unit can output audio signals locally and is intelligently controlled by the main host system. It requires no local configuration and is ready for operation after simple remote setup via dedicated management software.
