RD620 digital repeater

Hytera RD620 is a premium digital repeater tailored for business users. Adhering to the user-centered design concept, we meet the challenges of users in actual work. RD620 adopts embedded compact design, built-in duplexer, AC-DC power supply, lightweight, supports wall-mounted installation, saves space, supports multi-point IP networking, and achieves wider coverage of indoor and outdoor communication. the best choice.

Hytera RD620 Digital Repeater Product Introduction:
采用内嵌式紧凑设计,内置双工器、AC-DC电源,主机厚度仅为108mm,重量≤5kg。 Integrated design: Built-in compact design, built-in duplexer, AC-DC power supply, the thickness of the host is only 108mm, and the weight is ≤5kg.
带DC接口,可选外挂式电池,方便安装与更换,满足无间断通信的使用需求。 Plug-in battery installation design: with DC interface, optional plug-in battery, easy to install and replace, and meet the needs of uninterrupted communication.
支持数字和模拟两种模式,并自动识别数模信号,智能中转。 Digital-analog compatible, intelligent switching: support digital and analog modes, and automatically identify digital-analog signals, intelligent transfer.
采用温控低噪声风扇,温度过高时启动风扇,保障100%工作循环。 Cooling design: Use temperature-controlled low-noise fan, and start the fan when the temperature is too high to ensure 100% duty cycle.
满足在应急情况下的电源接入。 Emergency connection port: meets the power supply in emergency situations.
采用特色的设计方式,满足客户的多种型号双工器安装要求。 Featured duplexer bracket: It adopts a unique design method to meet customers' requirements for the installation of multiple duplexers.
主机操作面板自带各种状态指示灯、接口指示,方便用户操作。 Intuitive operation panel: The host operation panel comes with various status indicators and interface instructions, which is convenient for users to operate.
您可以使用RDAC PC工具、中转台尾针来完成信道切换。 16 channels: you can use the RDAC PC tool and the end pin of the repeater to complete the channel switching.
IP中继站互联可以将多个位置分散的相同或不同频段的中继台通过IP网络连接起来,移动终端自动漫游,实现语音和数据通信。 Flexible IP networking: Interconnection of IP relay stations can connect multiple relay stations of the same or different frequency bands scattered in multiple locations through an IP network, and mobile terminals automatically roam to realize voice and data communications.
通过背靠背的应用方案可支持模拟和数字对讲机在不同的工作模式下实现互通,允许模拟用户与数,从而确保模拟用户向数字的平滑过渡。 Analog / digital back-to-back: The back-to-back application scheme can support the interworking of analog and digital walkie-talkies in different working modes, allowing analog users and digital, thereby ensuring a smooth transition of analog users to digital.
通过PC软件可实现对远程(IP口)及本地(USB)中转台的监控、诊断和控制。 Remote diagnosis and control of the repeater: PC software can be used to monitor, diagnose and control the remote (IP port) and local (USB) repeaters.
尾针可同时输出两个时隙语音 Digital analog dual time slot voice output: tail pin can output two time slot voices at the same time
