可選配件
The network audio codec shall be IP-addressable and convert analog audio (mic or line level) to standard IP packets for transport over an IP-based network including local area, wide area and the Internet. The device shall be capable of simultaneous transport of audio, serial RS-232 data and contact closures. The device shall support three audio quality modes and have variable sample rate and audio bandwidth with a minimum latency/delay of 20 ms. Multiple error correction modes shall be available to address potential packet loss in high network traffic environments.
The network interface shall be 10BASE-T/100BASE-TX, Auto-Negotiation and utilize the network protocols TCP/IP, UDP, HTTP and RTP. The audio input shall be balanced, transformer-isolated, MIC/LINE switchable (-58 dBV to 0 dBV, 2k ohms) with adjustable volume control and plug-in screw connector. The audio output shall be balanced, transformer-isolated, (0 dBV, 600 ohms), with plug-in screw connector. Specifications shall include frequency response of 50 to 14k Hz and distortion of under 0.3% (1k Hz, sampling frequency 32k Hz).
The unit shall be capable of Unicast transmission to up to 4 simultaneous units/locations over LAN/WAN/Internet, and Multicast transmission to up to 64 simultaneous units/locations over LAN/WAN. The device shall include Java-based software for configuration, operation and management with password protected access. The device shall include a built-in web server for control and monitoring from any network-based PC with password protected access.
The control inputs shall include 8 channels, no-voltage make contact input, open voltage: 12 VDC, short-circuit current: 10mA with plug-in screw connector. The control inputs shall be individually programmable to initiate and terminate stored transmissions without the need for dedicated PC-based or other control equipment. Each unit shall have twenty programmable distribution presets. The control outputs shall include 8 channels, open collector output, withstand voltage: 30 VDC, control current: 50 mA max. with plug-in screw connector. Adjustable contact off delay time shall be available.
The front panel shall include Link/Active, Full-Duplex/Collision, Status, Error, Run LED indicators plus recessed Reset button. Firmware shall be FLASH-type and upgradeable from any network PC.
