DV4home
The DV4home is another member of the successful family of DV4 products. As usual it supports all digital modes, while simplifying and extending the supported functions. While it acts as a “home” for the DV4mini it can be easily used mobile or portable as well. It is a stand alone unit that does not need a PC to operate.
(automatic update of firmware via Internet)
There are 2 versions available, the DV4home and the DV4home compact.
DV4home compact
The DV4home compact is a barebone version which is an easy to operate stand alone device with a simple rotary-push button operation and a high temperature range built-in display. It contains a shielded compartment into which a DV4mini is inserted. The voltage range between 9V and 15V allows a direct connection to a vehicle’s power system without any additional power supply. The extreme temperature range from -40C to +85C ensures functionality even under the most extreme conditions.
The DV4home compact can be alternatively configured by the rotary-push button or by a PC using the Control Center software.
All modes of the DV4mini are supported: Fusion, D-Star, DMRplus, dPMR, P25 (NXDN later via software update)
D-Star (DCS,CCS,REF,XRF,XLX)MRplus (TS1 all / TS2 Reflectors or talkgroups)
dPMR(All Systems and codecs transparent mode)
P25(Phase 1 Only and all NAC transparent mode)
The DV4home compact can directly connect to the DMRPlus network or IPSC2 .
Connection to the internet can be made by:
Ethernet 10/100
WLAN using a USB 2 WLAN adapter
3G/4G(LTE) via USB 2 adapter
DV4home
The DV4home uses the same microcontroller platforms as the DV4home compact, but adds 2 AMBE3000 chips, a microphone and a speaker connector to the unit.
These components allow these additional functions:
Direct Internet transceive mode without a DV4mini by using the microphone and the external speaker. This is an economical alternative if no local wireless signal is needed. In this mode the DV4home supports D-Star, DMR, dPMR (and later NXDN via software update)
Dual mode support: even without a DV4mini inserted the unit can be simultaneously connected to a D-Star and a DMR reflector, using 2 separate speakers to play the respective audio streams.
Transceiver mode connects a D-Star or DMR radio via a plugged in DV4mini to a reflector.
Conference mode requires a DV4mini inserted into the unit and allows to use the built-in microphone/speaker connectors and the RF connection through the DV4mini to a DMR or D-Star radio. This mode works in D-Star and DMR.
Transcode mode allows to use a digital radio in one mode and connect to a reflector in another mode. Use your D-Star radio to try out DMR! The following conversions are supported:
D-Star → DMR
DMR→ D-Star
Later via software update:
All –>. Fusion (C4FM)
Fusion (C4FM) → All
DMR/D-Star Bridge mode allows to interconnect DMR and D-Star reflector rooms using the licensed DVSI AMBE chips. This mode bears the risk of creating loops in the network, therefore a free license key is required which also helps that the installations can be supported by the network administrators to assure a flawless integration.
IPSC2 and DMRplus bridge permits the connection between DMRPlus.
