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.
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:
WLAN using a USB 2 WLAN adapter
3G/4G(LTE) via USB 2 adapter
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
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.
