TSR
What’s required?
Repeater Call Sign
First, you need is a unique / club call for the repeater.
* You can not have the same call sign in 2 different “roles” in the D-STAR
network. (eg, the repeater call sign can not also be your individual call sign.)
You will need a unique / club call sign for your repeater system that is not
used anywhere else in the network.
TSR
What’s required?
Repeater Components
Next, you need the desired repeater modules. The RP2C is REQUIRED
for the D-STAR repeater system.
The current D-STAR repeater modules are:
RP2D
1.2GHz, 128K Digital Data (DD)
RP2V
1.2GHz Digital Voice (DV)
RP4000V
440MHz Digital Voice (DV)
RP2000V
144MHz Digital Voice (DV)

Gateway Configuration Diagram
TSR
What’s required?
Internet Connection (Fixed IP address)
The D-STAR gateway software REQUIRES a fixed IP address and, at
least a DSL speed connection.
You will also need a router capable of:
Class “A” internal subnet (LAN) 10.0.0.1 / 255.0.0.0
Port forwarding
Setting a fixed IP address, such as for PPPoE for WAN
Refer to the RS-RP2C manual for additional requirements.
(The Linksys WRV54G meets all the requirements)
TSR
What’s required?
Gateway server PC (Linux)
This is what we are here for, right?
Minimum PC requirements (per Icom)
Linux OS (recommend Fedora Core 3 or 4)
Pentium grade 2.4GHz or faster CPU
At least 512MB RAM
2 LAN cards (NIC from Intel recommended)
At least 10GB hard drive free space

TSR
Setup Verification
You will want to check for
two services to be
running.
Type ps –ef | grep dstar
You should see at least two
programs running
dsipsvd
dsgwd
Without both, it will not
work!
TSR
Setup Verification
If the services are not
running, we can check
the log file at:
/var/log
Both logs are saved as:
dsipsvd.log
dsgwd.log
TSR
Setup Verification
The easiest way to see if it
synchronized is to look
at the dstar.local.db
file.
You can use the GUI by
typing “startx” on the
command line, if
desired.
Open the file:
/var/named/chroot/var/named/dstar
.local.db
D-STAR
Adding Users
Icom America Inc.
TSR
TSR
Adding users
First, you need to reserve
IP’s for the users.
Open a terminal window
and type: cd /tmp
Next type:
Echo “reserve” >
/tmp/dsipsvd-cmdin
TSR
Adding users
To see the reserved IP’s,
type:
cat /tmp/dsipsvd-cmdout
You should see results like
this 
IP’s are reserved in blocks
of 32.
As the administrator, we
recommend creating
a log file to track
these IP addresses.
TSR
Adding users
Now you can add the
users.
You will add 1 call sign
user per reserved IP
(fixed IP address,
10.x.x.x).
The command line is
shown in the guide.
Syntax is VERY important!
TSR
Adding Users
From the linux command line:
Change directories to tmp
cd /tmp
The “add user”command format is:
echo "add {user_ID}|{area repeater call sign}|{zone repeater call sign}|{GW IP
address}|{users assigned IP address}|{alias name for DNS} > /tmp/dsipsvd-cmdin"
User ID is the users call sign it must be 8 characters. add spaces to
the end
TSR
Adding Users
echo "add {user_ID}|{area repeater call sign}|{zone repeater call sign}|{GW IP
address}|{users assigned IP address}|{alias name for DNS} > /tmp/dsipsvd-cmdin"
Area Repeater Call Sign is the system call sign with the letter [A] in the
8th position, use spaces between the call sign and the [A]
Zone Repeater Call Sign is the system call sign it must be 8
characters add spaces to the end
GW IP Address is the public address of the gateway system
Users Assigned IP Address is the address assigned to the user by the
local address coordinator
Alias Name for DNS is the users call sign, in lower case, with no
spaces at the end.
TSR
Adding Users
echo "add {user_ID}|{area repeater call sign}|{zone repeater call sign}|{GW IP
address}|{users assigned IP address}|{alias name for DNS} > /tmp/dsipsvd-cmdin"
The following is an example.
echo "add W7JRL71 |N7IH9 A|N7IH9 |65.102.167.146|10.140.194.xxx|w7jrl71" >
/tmp/dsipsvd-cmdin
TSR
Important Points!
Only users added to the gateway can cross the D-STAR gateway to
access the network.
Once a user is added to the D-STAR gateway, they have gateway rights
via any D-STAR gateway pointed to the same trust server.
Any user can operate locally on the repeater, with or without a call sign.
TSR
Adding users
Once all the users are
added, type:
cat /tmp/dsipsvd-cmdout
You should see, per the
number of entries:
200 Command OK
D-STAR
Checking GIP, RIP and MNG Tables
Icom America Inc.
TSR
TSR
Gateway server
The gateway software uses 3 tables:
RIP – Reserved IP addresses
GIP – Gateway IP addresses
MNG – Call sign manage table
The backup tables are stored in the /var/dsipsvd folder
The “production” files are resident in memory, downloaded from the
trust server. You can “write” the tables to a text file to view, if
desired. You can not edit them direct because they are in memory.
All files are updated / merged automatically with the trust server and all
the other gateways on the network at least once a day.
TSR
GIP (gateway IP), RIP (reserved IP) and MNG (call
sign manage) tables.
All 3 “Live” tables are in memory and can not be directly edited.
All 3 tables store a backup in the /var/dsipsvd folder.
You must “write” the tables from memory in order to view the current
files.
TSR
“Writing” tables
From a terminal window,
type the command:
echo “write MNG /tmp/mng.txt” >
/tmp/dsipsvd-cmdin
Replace “MNG” with “GIP” or “RIP”
TSR
“Writing” tables
View the files you just
created by typing:
cat /tmp/mng.txt
Replace “MNG” with “GIP” or “RIP”
TSR
GIP (gateway IP) and RIP (reserved IP) tables.

Testing and Going “Live”
Icom America Inc.
TSR
TSR
Testing and going “Live”
In order to go “live” on a D-STAR network, we recommend being 100%
functional on the Icom test system first. Contact Icom D-STAR
support team for testing at [email protected]
If you have ANY questions, contact Icom before you do something. We
don’t want to corrupt the network and make it bad for all the other
users.
Once operational on the “test” network, you need to “kill & clean” your
gateway, change the TRUST_SERVER IP address, and re-boot
your PC.
TSR
Testing and going “Live” (cleaning)
To “clean” your system and start fresh (on the live network):
Kill all “DSTAR” services
1). Execute a 'ps -ef | grep dstar' command. This will give you the
process numbers for the dsgwd & dsipsvd processes.
2). Execute a 'kill xxx' command, where 'xxx' is the process number
revealed in step one, for each of the two processes.
TSR
Testing and going “Live” (cleaning)
3). Execute a 'rm /var/dsipsvd/*.*' command. Verify the /var/dsipsvd
directory is empty.
4). Edit the file /var/named/chroot/var/named/dstar.local.db with a text
editor and delete any call sign entries after #DSTAR A RECORD.
5). Execute a 'cat /etc/dsipsvd.conf' command, and ensure that your
TRUST_SERVER points to the proper server IP for the desired
network xxx.xxx.xxx.xxx
Use a text editor, such as joe or the GUI interface to change the
TRUST_SERVER IP, if needed.
TSR
Testing and going “Live” (cleaning)
6) Execute a ‘reboot’ command on your gateway.
7) The gateway will come up clean, and pull new files from the
TRUST_SERVER, then re-synch with each of the other gateways.
TSR
TRUST_SERVER
A trust server, IARoot, is provided by Icom as a service to the D-STAR
community.
There are other trust servers around the country such as USRoot
provided by K5TIT in Dallas TX.
You can use your own private trust server to create your own D-STAR
network or you can link to one of the other trust servers around the
country, if desired.
Any PC running the gateway software can be set as a trust server to
create your own private network.
The Gateway server MUST be located at the repeater. The 172.16.0.20
LAN segment (controller to gateway) is VERY sensitive to latency!
TSR
Important Points!
All gateways pointed to the same trust server share the same GIP, RIP
and MNG tables.
These tables CAN NOT be changed or “cleaned-up” on your own. It
requires all connected gateways to be “killed” and “cleaned” first.
Once all connected gateways are “killed”, the trust server files can be
edited BEFORE any gateway is re-booted.
When the gateways are “cleaned” and re-booted, they will download the
new GIP, RIP and MNG tables from the TRUST_SERVER.

D-STAR
How it works
Icom America Inc.
TSR
TSR
Understanding how it works
D-STAR utilizes call signs to “route” the radio call.
Every repeater must be assigned a unique call sign (club call
recommended).
Every owner / operator programs their radio with their own call sign.
Call sign is transmitted digitally with each transmission.
No need to voice ID with D-STAR since digital ID is part of each TX.
TSR
Understanding how it works
Each radio has 4 call sign fields to be programmed. What you need to
know to program a radio is:
Operating frequency
MyCall
UrCall
Rpt1
Rpt2
Simplex or Duplex frequency
Your call sign (primary operator)
Call sign of the person / zone being called
1st repeater
2nd repeater
TSR
Understanding how it works (Simplex)
To complete a local simplex call, program 2 fields along with the
frequency in the radio.
MyCall
UrCall
My call sign (eg. W7JRL)
Your call sign or “CQCQCQ”
MyCall - W7JRL
UrCall – CQCQCQ
MyCall - N9JA
UrCall – KD7DIQ
MyCall - KD7DIQ
UrCall – CQCQCQ
TSR
Understanding how it works (Simplex)
In this example, all parties in digital mode hear all the traffic on the
simplex channel.

My call sign (eg. W7JRL)
Your call sign or “CQCQCQ”
Local repeater call sign
TSR
Understanding how it works (Repeater)
When you program your radio’s
“RP1” location, and the proper
frequency, your radio tells the
desired repeater to activate.
This is similar to PL tones in
analog.
Eg. MyCall
