**** De door Hamshop aangeboden Hytera apparatuur is bestemd voor de radiozendamateur (hobbyist). De firmware (besturing) is door deze groep hobbyisten zelf geschreven en is kosteloos. Er is voor deze groep geen service ondersteuning. Voor de professionele markt wordt er vaak firmware en software op maat gemaakt en is er professionele service ondersteuning. Hier gelden dan ook andere prijzen voor! Bel of mail ons indien u bedrijfsmatig een digitaal communicatie netwerk wilt opbouwen. ****


Flexible IP networking
Hytera's DMR repeater can be connected to an IP-based communication network with multiple locations. The roaming function is used to provide radios in this radio network with voice and data services across cells.

 

Connecting VoIP private automatic branch exchanges (PABX)
The RD625 repeater makes it possible to connect existing VoIP telephone systems to the DMR radio network. This allows DMR radio subscribers to hold half-duplex conversations with participants from the telephone network. Telephone subscribers have the option of making either individual or group calls in the radio network.

 

Analog and digital operation with the ability to switch automatically
The RD625 repeater can be operated both in analog and in digital mode and is completely compatible with analog systems currently in use. The device can automatically change between digital and analog mode depending on the type of receiver signal, saving both time and money by eliminating the need to configure frequencies and channels manually.

 

Automatic AC/DC switchover
The integrated power supply of the RD625 automatically chooses between alternating current and direct current. This makes it possible to provide a fail-safe radio signal by connecting the repeater to an independent source of direct current (UPS) in addition to the normal supply of power. If the AC supply fails, the RD625 switches to the second power supply automatically.

 

Easy installation
The RD625's well-engineered design makes wall mounting easy using the optionally available wall bracket. This makes it possible to install the repeater flexibly and conveniently in buildings.

 

Repeater diagnostics and control system (RDAC)
A PC-based application can be used to monitor, inspect and control the RD625. The software supports network access from multiple points and allows administrators to monitor the DMR radio network.

 

Compact all-in-one design
The RD625 combines transmitter and receiver components, the voltage supply and the duplexer (optional) in its compact chassis.

 

Repeater access management
To ensure a high level of security, the RD625 features a repeater access monitor that protect the radio network from unauthorized access attempts.
