1. Desktop design, with 7 "800 × 480 graphics dot matrix K600+65K color display touch screen
2. It comes with number keys and function key interface. Clear display and sensitive touch. When there is no operation, it enters the sleep, low-power and power-saving state. Humanized human-machine operation interface.
3. Support 8-way zoning shortcut key setting, one-button call zoning, one-button call all-area broadcasting; Call any partition, support direct operation call or intercom to any terminal;
4. Direct operation monitoring (environment monitoring) is supported for any terminal according to the actual environment.
5. Designed with embedded computer technology and DSP audio processing technology
6. High-speed industrial-grade chip is adopted, and the startup time is less than 1s.
7. Built-in 1-channel network hardware audio decoding module, supporting TCP/IP, UDP, IGMP (multicast) protocols, and realizing networked transmission of 16-bit CD audio signal.
8. It supports the full-duplex two-way intercom function, with its own network echo cancellation module.
9. Two-way intercom is realized between terminals, and the network delay is less than 10ms. At the same time, the network echo howling was completely suppressed.
10. Support a variety of call strategies, including call waiting, call transfer, and unattended alert.
11. Built-in 3W full-frequency high-fidelity speaker to realize two-way call and network monitoring.
12. One USB input, one φ 3.5MIC input socket, matching 95% of microphones on the market.
13. One audio line output, external power amplifier; One audio line input provides multi-source transmission.
14. One circuit of alarm triggers short circuit output and cascades out the warning equipment; A short circuit input can be used to trigger preset voice prompt (or alarm).
15. With USB flash disk function, the USB flash disk automatically writes the IP address
16. The music program in the USB flash disk can be directly played locally, and the music in the USB flash disk can be converted into network data stream and transmitted to other terminal devices.
17. High-fidelity recording function, which can record the microphone and line input signals with high quality. The recording file is stored in the server and can be played at any time
18. Industrial-grade special motherboard design, 400MHz high main frequency ultra-low power embedded industrial-grade processor, faster processing speed, stronger operation performance, can work continuously and stably for a long time.
19. Built-in memory chip, built-in memory chip, internal files are managed remotely through the network, and the network file transmission speed reaches 2MB/S, without any movable mechanical parts, with super durability and reliability.
20. As the core operating platform, the embedded real-time operating system is easy to expand, develop and upgrade, has superior network support, high security, and strong compatibility, and protects the system from the interference and damage of viruses.
21. Programming timing tasks, supporting offline file playback, programming multiple sets of timing schemes, and supporting optional execution terminals.
22. It has backup function. The addition of standby industrial personal computer can realize the sharing of server software data, real-time detection of the working status of the main industrial personal computer, and realize the automatic switching between the main and standby in case of failure, which can completely replace the management and control function of the main industrial personal computer.
23. Standard network interface, full-rate connection up to 100M, supporting cross-network segment and cross-routing mode.
24. Support remote upgrade of server system and terminal firmware, and support data backup import and export
25. Automatically obtain the function of finding and adding IP addresses.
26. Support real-time intercom and call. The default call/acquisition sampling rate is 32KHz 16bit PCM distortionless coding format
