Intro uction
The DV4home is another member of the successful family of DV4 products. It supports all di ital
modes, while simplifyin and extendin the supported functions. While it acts as a "home" for the
DV4mini it can also be easily used mobile or portable. It is a stand-alone unit which does not need a
PC to operate. (DV4mini not included)
You can describe the DV4home as an IP (Internet) transceiver.
There are 2 versions available, the DV4home and the DV4home compact.
Description
The DV4home uses the same microcontroller platforms as the DV4home compact, but adds 2
AMBE3000 chips, a microphone and a speaker to the unit. There is a built-in speaker and the
microphone is included.
These components allow the followin additional functions:
Direct Internet transceiver mode without a DV4mini by usin the microphone and the external
speaker. This is an economical alternative if no local wireless si nal is needed. In this mode the
DV4home supports D-Star, DMR, dPMR, NXDN (and later *C4FM via software update)
Dual mode support: even without a DV4mini inserted, the unit can be simultaneously connect to a D-
Star and a DMR reflector, usin 2 separate speakers to play the respective audio streams.
Transceiver mode connects a D-Star or DMR radio via a plu ed in DV4mini to a reflector.

 5 
Conference mode requires a DV4mini inserted into the unit and allows the use of the built-in
microphone/speaker connectors and the RF connection throu h the DV4mini to a DMR or D-Star
radio. This mode works in D-Star and DMR.
Transcode (later via software update) mode allows to use a di ital radio in one mode while
connectin to a reflector in another mode. Use your D-Star radio to try out DMR! The followin
conversions are supported:
D-Star → DMR
DMR→ D-Star
All → Fusion (C4FM)
Fusion (C4FM) → All
DMR/D-Star Brid e mode allows interconnectin DMR and D-Star reflector rooms usin the licensed
DVSI AMBE chips. This mode bears the risk of creatin 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 inte ration.
IPSC2 and DMRplus brid e permit the connection between DMRPlus.

Digital Mo es
The DV4home can handle five di ital modes:
D-Star
D-Star was developed in Japan 1999/2000 especially for ham radio and it became the
leadin system worldwide due to its clear and relative simple user interface. Voice is
bein transformed by the AMBE Vocoder into a compressed di ital data stream of
3600 bits/s.
In addition, there is a data channel with 1200 bits/s for a total data rate of 4800
bits/s. This data si nal modulates a carrier, so that a lo ical 0 is one frequency and a
lo ical 1 a second frequency. This is called 2FSK (two frequency shift keyin ) or GMSK
(which are the same, however the si nal is modulated usin a bell curve). This si nal
can be used to modulate most FM transceivers (via the packet radio socket).
This is the reason why there are many homemade D-Star solutions.
Three reflector systems are used for communication. DCS (most common), D-Plus,
REF reflectors (mostly in En lish speakin countries), and the x-Reflector system
which plays a minor role. The DV4home enables communication on all these systems.
DMR
DMR was ori inally desi ned by ETSI for commercial applications. This is evident in
the user interface where numbers are used in lieu of call si ns. DMR modulates with
4FSK, indicatin that it uses 4 frequencies (compared to D-Star with 2 frequencies).
This allows doublin the data rate to 9600 bit/s. The hi her rate allows the
transmission of 2 channels at the same time (2 time slots). The DV4mini always works
in simplex mode in DMR.
If you use time slot one (TS1) you have to set your radio to color code 1 (CC1) and the
talk roup you want to use, i.e TG311 or TG262 etc. Be aware that you have to enter
the talk roup number into the receive roup list of your radio too, or your squelch
will not open. This is a common error made by first time users and it is very
frustratin .
When you use TS2, you always transmit and receive on TG9 (local) Then this routed
by the DV4mini and the DMR Plus system into the selected rooms.

 9 
So on TS2 you use CC1, TG9. A ain, you need to pro ram your radio accordin ly, and
a ain do not for et to put TG9 into your receive roup list!
There are multiple DMR networks available:
The DMR Plus network is developed and operated by the DV4 team, the
Brandmeister network by a team of Russian developers and the DMR-MARC network
by the Motorola Amateur Radio Club.
The DMR Plus network reflectors and the Brandmeister reflectors can be selected in
the expert settin s.
DMR reflectors have numbers in the ran e of 4000 to 5000. Each re ion has its own
reflector, which can be selected in the DV4mini menu.
The DMR-MARC network can be selected by usin the IPSC2 version of the control
center. Select the appropriate IPSC2 server as your DMR server and you can connect
to the Motorola TG on TS1 and to the DMR Plus TG on timeslot 2.
C4FM-Fusion
C4FM-FUsion is a system developed by YAESU. It is based like DMR on 4FSK, and also
transmits 4 frequencies with a total data rate of 9600 bits/s. It uses the same AMBE+
Codec as DMR, but needs only 3600 bits/s. The extra bits are used in C4FM-Fusion in
a different way. They can be used for data transfer (e. . GPS) but also for additional
error correction to make the speech more stable durin interference. There is also a
mode for hi h speech quality which uses all bits for speech only.
C4FM -Fusion reflectors are named FCS001 (Europe), FCS002 (USA), FCS003 (Canada),
etc. All DV4minis / DV4homes connected to a reflector can hear each other. It is very
easy to connect a C4FM/Fusion repeater to the FCS reflector system.
P25
P25 is a di ital system that is mostly used by public and private emer ency services
worldwide.
Currently the DV4minis have 2 reflector systems available:
● PCS001 for Europe, located in Switzerland
● PCS002 for the Americas, located in Florida

 10 
PMR:
dPMR is a DMR system from China which uses several Chinese Codecs instead of the
DVSI AMBE codecs commonly used by other di ital systems. These radios are cheaper
as they do not need to pay license fees for the Codecs. Practically you have to use
radios from the same manufacturer on both ends of the communication, as they are
not much standardized. This is why we call the mode experimental.
System requirements
The followin components are necessary:
1. Internet access.
2. A PC with Windows 7, 8.1, 10, for firmware up rade.
3. Web browser (any platform) for remote control.

 11 
Initial setup
Before turnin on the DV4home for the first time make sure you have a wired
Ethernet connection to your home router. When you turn on the DV4home for the
first time it will show on the display its IP address (obtained by your home router via
DHCP) with an http link necessary to setup your call si n and your DMR ID (CCS7 ID).
The IP address scheme will vary from one place to another dependin on the local
network confi urations (LAN) or the router manufacturer’s default subnet.
Here’s an example for the 192.168.10.0 /24 network:
http://192.168.10.121/user.html
Now enter usin any web browser in your home network and type the link shown on your
DV4home screen. You should then access the DV4home user setup, see ima e above. Enter
your DMR ID (CCS7 ID) and your call si n, click ok and you’re done. You can chan e the user
settin s anytime by accessin the same URL.
Make sure ou have entered our CCS7 ID (DMR ID). The DV4home will not work without it.
If you do not have a CCS7 number go to http //dmrmarc.net and click on
Register ID. It can take up to 72 hours until you get your number by email.

Operating the DV4home
The DV4home is a standalone device and there are two different ways it can be
configured. The first one is via the DV4home menu button on the front panel and the
second one is via a web browser interface since it has an integrated web server.
Remote webserver
When you enter the IP address of your DV4home into a web browser, you will access
the DV4home webserver.
DV4home home pa e example: http://192.168.10.121
On the DV4home home pa e you will see the current mode status, if it does not
show press F5 on your computer keyboard to refresh. The DV4home as two
inte rated AMBE chips, which allow you to have two separate modes operatin at
the same time. The current software version only supports D-Star and DMR, in the
ima e below you see that there are two modes active and it shows on which
reflectors they are connected.
This image is from a preliminary software version, the other modes / reflectors will be
available later this year.

 13 
Connecting to a reflector
Metho #1: Using any web browser
When you access the home pa e of the DV4home webserver and click on DSTAR-DCS,
you will find a drop down menu that allows you to select a DCS reflector and room.
Select a DCS reflector from the drop down menu, a module (port) and click ok to
connect. After connectin you will have the reflector status information displayed on
the web pa e. See below.

 14 
The procedure is the same for all other modes.
Metho #2: Direct on the DV4home
To access the main menu, do a brief push on the MENU (volume) knob.
The * indication shows the current selected mode, to chan e to another mode just
turn the MENU knob.

 15 
After selectin the operatin mode do a brief push to access the submenu of that
mode.
When you turn the MENU knob you will find 5 options;
1. Reflectors ( D-Star DCS in the example below)
2. Ports (DCS in the example below)

 16 
3. Link … (DCS in the example below)
4. Unlink … (DCS in the example below)
5. Exit Menu

 17 
Programming a reflector using method #2
The procedure below is showin how to select a mode, reflector, port and how to
activate it. This example is based on the DCS reflector, please note that it is the
same procedure for all the other modes. In this example we will pro ram DCS008
module C. To return to the main screen just press and hold the MENU knob for a few
seconds.
From the main menu select the operatin mode by turnin the MENU knob. Push
briefly the MENU knob. The ima e below shows the submenu screen of the DCS
selection.
Push briefly the MENU knob to access the DCS REF confi uration menu. The current
confi uration is for DCS-001 Port A.
When you turn the MENU knob the DCS-001 will chan e, then select the desired DCS
and press and hold the MENU knob to complete the selection. In the example below
we selected DCS-008.

 18 
When you press and hold the MENU knob for selectin the reflector you will et back
to the submenu. Turn the MENU knob for the next submenu selection, DCS Port and
push the knob briefly. Select the desired port by turnin the MENU knob and press
and hold the MENU knob to complete the selection.
When you do a press and hold on the MENU knob for selectin the port it will brin
you back to the submenu. Turn the MENU knob for the next submenu selection, Link
DCS and push briefly. This completes the reflector selection and you are now
connected.

 19 
Please note that the setup is the same for all reflectors except for a small difference
in DMR, when you select a reflector there is no port. Since there are lot of them the
port selection is chan ed by usin different increments (step) to navi ate throu h the
reflectors. See the ima e below.
Transmitting with the DV4home
The DV4home operates like a normal transceiver without the RF. It has two
separate IP transceivers (2 x AMBE chips) so you need to select which one you will
be usin ; this selection is similar to switchin the microphone between two different
active VFOs or bands on a RF transceiver. Dependin on your choice it will transmit
on the active reflector connection for that mode.
The * after the mode indicates the current active mode. To chan e modes on the
main screen, just press and hold the MENU knob then it will switch the mode.
