dSPEC and Resyn Network Overview
Resyn and dSPEC support various IPv4 network configurations. By default, Resyn and dSPEC support automatic IP
addressing as do most computers. Sometimes static IP addresses for dSPEC are preferred or required. Refer to
Address Tips on page 4 for help on choosing automatic or static IP addresses for dSPEC.
There are various methods for connecting a computer running Resyn to dSPEC:

The computer running Resyn is connected either wirelessly or via an Ethernet cable
to one or more dSPECs via a common Ethernet switch. Each dSPEC is connected with
its own Ethernet cable.
The computer running Resyn is connected to one or more dSPECs through a TCP/IP
router to a remote location accessible via the Internet.

Network Tips
IP Address Tips
There are two types of automatic IP addresses: APIPA and DHCP. dSPEC is supplied with Automatic Private IP
Address (APIPA) assignment enabled. If plugged in to a network that has a Dynamic Host Configuration Protocol (DHCP)
server dSPEC will automatically favor a DHCP address.
Use automatic IP addresses for convenience and temporary connections. Depending on your DHCP server,
automatic IP addresses may time out in as little as 12 hours. Resyn and dSPEC will disconnect with an error if the IP
address on either side changes.
Use static IP addresses when Resyn must remain connected for very long periods of time or via Remote
Management, or if some other manufacturer’s equipment requires the computer’s IP address to be static. Also, static IP
addressing should be used for all permanent installations, where connection reliability is a must.
IMPORTANT: For non-remote management situations, dSPEC must be on the same subnet as the Resyn computer
in order to connect. Understanding subnets is essential when using static IP. Read about subnets at Wikipedia:
http://en.wikipedia.org/wiki/Subnetwork. Read more about TCP/IP Fundamentals online at
http://technet.microsoft.com/en-us/library/cc743319.aspx which is also available in PDF form at
http://download.microsoft.com/download/9/4/6/946958ef-7b86-4ddc-bfdb-c7ed2af4ce51/TCPIP_Fund.pdf.
Ethernet Cable Tips
dSPEC is supplied with a CAT-5e Ethernet cable. dSPEC must connect to your computer or network via a CAT 5e (or
better) Ethernet cable. A standard cable or a crossover cable can be used. The dSPEC will auto-detect the cable type.
Note: Gigabit Ethernet crossover cables are not compatible with earlier versions of Ethernet crossover cables.
dSPEC does not work with Gigabit Ethernet crossover cables.
Please make sure to use a high quality Cat 5e or better Ethernet cable that is known to work properly. Poor quality
or damaged cables can limit Resyn’s ability to find dSPECs on the network, or cause data errors and that may result in
lost data or system crashes. A cable tester (such as Klein Tools LAN Scout™ Jr.) is recommended.
The maximum length for Ethernet cables is 100 meters or 328 feet. Read more about Ethernet cables online at

Suggested Steps for Troubleshooting
This section explains steps to try to resolve common problems that may arise when attempting to connect Resyn
to dSPEC.
1. Try to connect
Load and Connect vs. Store and Connect
Resyn and dSPEC transfer settings as part of the connect process, settings remain synchronized while connected,
and dSPEC remembers those settings after disconnect and power cycle. The direction that settings are transferred
during connect differ between: Connect | Load from dSPEC(s) and Connect | Store to dSPEC(s).

2. Click Refresh in Resyn
Click Refresh on the Administer | Networking Screen.
Page | 10
Or click Refresh on the Connect Dialog.
dSPEC should appear within a few seconds.
3. Verify Ethernet cable connections
The Ethernet jack is on the back of dSPEC. Verify that both ends of the Ethernet cables are securely latched and
you have a known working Ethernet cable.
4. Verify dSPEC power connections and heartbeat
Verify the heartbeat light on the front of dSPEC is blinking.
Page | 11
If the dSPEC heartbeat light is not blinking, please contact Community. Additionally, you can try cycling power on
the unit.
Verify the power cord is securely connected on the back of the dSPEC and to the power outlet. Verify the power
outlet has power.
5. Cycle power on the dSPEC(s) (turn off amps first)
Turn off any amps that are connected to the output of the dSPEC(s).
Remove power from the dSPEC(s). dSPEC does not have a power switch – so do this by switching off the power
source or unplugging the dSPEC power cord.
Reapply power to the dSPEC(s).
Turn on any amps that were turned off above.
6. Restart Resyn
Click [ X ] to close Resyn.
Save changes if you wish.
Start Resyn by double-clicking on the desktop icon , or you can start Resyn from your Start menu. Go to Start >> All Programs >> Community Professional Loudspeakers >> Resyn …and click on Resyn.
Page | 12
7. Restart the Resyn computer
Click the Windows Start button , click Restart, or click the arrow next to the Lock button and then click
Restart.
8. Verify IP Addresses
Ensure the local computer shares an IP subnet with dSPEC.
If automatic IP addresses are being used, please set the Resyn computer address to automatic as described
below.
If static IP addresses are being used, please ensure the local computer and all dSPECs are configured to have
unique IP addresses on the same subnet.
Tip: Read more about subnets and automatic versus static IP addresses in IP Address Tips on page 4
Resyn and dSPEC generally work best with automatic IP addressing. Community ships dSPEC with automatic IP
addressing enabled. Most computers also default to having automatic IP addressing enabled. So generally IP
addresses do not have to be manually set for Resyn to communicate with dSPEC.
There are exceptions however. You may have used gear from other manufacturers that required you to set a
static IP address on the local computer. In this case you will want to re-enable automatic IP addressing for Resyn.
Alternately you may decide you prefer your dSPEC and computer to have fixed addresses – especially if you need the
computer to concurrently communicate with other manufacturer’s equipment and dSPEC. IP Address Tips on page 4
can help you decide if static IP addresses are needed for your network.

Verify Windows IP Address Configuration
To re-enable automatic IP addressing on Windows Vista or Windows 7/8 click the Start button , type ncpa.cpl
then <Enter>; on Windows XP click Start, click Run, type ncpa.cpl then <Enter>. Right click on the connection that will
most likely be used to connect to dSPEC and choose properties. Ensure properties for IPv4 are set as follows:
• General: Obtain an IP Address automatically is checked.
• Alternate Configuration: Automatic private IP address is checked.
Click Ok on the open dialogs to save settings and dismiss the dialogs.
If you are not using automatic IP, configure the static IP appropriately. Make sure that Resyn and dSPEC are on the
same subnet. For additional information regarding assigning a static IP address, contact your ISP provider or review
Address Tips on page 4.

On Windows Vista or Windows 7/8 click the Start button , type ncpa.cpl then <Enter>; on Windows XP click
Start, click Run, type ncpa.cpl then <Enter>. Right click on the connection that will most likely be used to connect to dSPEC and choose Disable.
Re-enable the network connection. Right click the connection and choose Enable.
Page | 15
10. Temporarily turn off or disable the Windows wireless adapter
Sometimes a wireless connection can interfere with Resyn’s ability to communicate over a separate wired
Ethernet connection on that same computer. If you are not using the wireless connection it can be temporarily turned
off when using dSPEC. Don’t forget to turn it back on when you are done.
Note: Do not turn off the wireless adapter if you know you are actually using it to communicate with dSPEC.
Many computers have an external switch that can be used to turn off the wireless adapter. If yours has a switch use the switch to disable wireless connections. Otherwise on Windows Vista or Windows 7/8 click the Start button ,
type ncpa.cpl then <Enter>; on Windows XP click Start, click Run, type ncpa.cpl then <Enter>. Right click on the
wireless connection and choose Disable.
Page | 16
11. Verify a Windows VPN connection is not acting as the default gateway
Is there a Virtual Private Network (VPN) connection on the Resyn computer? If so it must be configured to allow
Resyn to locally connect to dSPEC – even if it is not being used for Resyn or dSPEC. Specifically the VPN Connection
TCP/IP or TCP/IPv4 Advanced option for Use default gateway on remote network should be unchecked. To do this on
Windows Vista,7 or 8, click the Start button , type ncpa.cpl then <Enter>; on Windows XP click Start, click Run, type
ncpa.cpl then <Enter>. Right click on the VPN connection and choose properties. Highlight TCIP/IPv4 and click
properties. Click Advanced. Ensure IP Settings are set as follows:
• Use default gateway on remote network is unchecked.
Click Ok on the open dialogs to save settings and dismiss the dialogs.
Page | 17
12. Temporarily turn off all Windows security software and firewalls
To configure Windows Firewall on Windows Vista,7 or 8, click the Start button , type firewall.cpl then <Enter>;
On Windows XP click Start, click Run, and type firewall.cpl then <Enter>. Follow instructions on screen to turn
Windows Firewall off.
Security Software is offered from various vendors has various means by which they can be turned off.
Please note that some security software may indicate it is turned off when it is still partially running in the background.
If this is suspected try to temporarily run windows in safe mode with networking as described below.
After Windows firewall and all security software is off, begin again at step (1.) to see if Resyn can connect.
If Resyn and dSPEC can connect with the Windows security software and firewall turned off the security software
and firewall need to be configured to allow Resyn and dSPEC to operate. Reconfigure the security software and
firewall per Verify Windows Security and Firewall Settingson page 17
.
IMPORTANT! Don’t forget to re-enable your security and firewall after it is properly configured.
13. Temporarily run in Windows in Safe Mode with Networking
Start Windows in Safe Mode with Networking as follows:
a. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
Click the Start button , click Restart, or click the arrow next to the Lock button and then click
Restart.
b. Do one of the following:
• If your computer has a single operating system installed, press and hold the F8 key as your computer
restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you will
need to try again by waiting until the Windows logon prompt appears, and then shutting down and
restarting your computer.
• If your computer has more than one operating system, use the arrow keys to highlight the operating
system you want to start in safe mode, and then press F8.
c. On the Advanced Boot Options screen, use the arrow keys to highlight Safe Mode with Networking.
After Windows starts begin again at step (1.) to see if Resyn can connect.
If Resyn and dSPEC can connect in Safe Mode with Networking the Windows security software and firewall turned
off, the security software and firewall need to be configured to allow Resyn and dSPEC to operate. Reconfigure the
security software and firewall per Verify Windows Security and Firewall Settings on page 17
.
IMPORTANT! Don’t forget to re-enable your security and firewall after it is properly configured.
14. Verify Windows Security and Firewall Settings
Resyn uses TCP/IP packets to communicate with dSPEC. Many 3rd party security suites such as Symantec Norton,
McAfee, and Zone Alarm can block TCP/IP communication between Resyn and dSPEC. With the exception of Windows
Firewall, we recommend disabling security software during the installation and initial connection process. Enabling or
disabling most security software requires Windows to be restarted to take full effect. Later the software can be reenabled – and if it does interfere with the connection between Resyn and dSPEC – it can be configured as described
below.
Running more than one firewall on Windows is generally not good practice as they can interfere with each other
and prevent network communication. Running more than one antivirus program on Windows is also generally not good
practice as they also can interfere with each other and prevent normal operation. A simple configuration of only one firewall and only one antivirus program has been proven effective, i.e. Windows Firewall and VIPRE Antivirus.

Firewall Settings
Resyn works best with Windows Firewall. Simply install Resyn and it will automatically configure Windows
Firewall for dSPEC connections.
If another firewall is used, which is not recommended, it must be set up to allow Resyn to communicate with
dSPEC. It is generally easiest to grant access in broad strokes, i.e. grant Resyn full network access for both outbound
and inbound rules. If there are stringent security requirements individual TCP and UDP rules can be set up per the
following table.
Table 3 Specific Firewall Rules for Resyn Computer

col
Allow outbound connections
UDP Allow Port 3400
Allow Ports 1024 through 65535
Allow IPv4 Broadcast
Optional: Allow IPv4 Multicast to 239.255.1.1
15. Verify Windows Power Options
It is generally best to configure the Resyn Computer to always stay on because if the computer hibernates or goes
to sleep dSPEC connections will be closed. On Windows Vista or Windows 7/8, click the Start button , type
powercfg.cpl then <Enter>; on Windows XP click Start, click Run, type powercfg.cpl then <Enter>. Follow instructions
on screen to choose a power scheme or plan such as High Performance or Always On. The important point is to
ensure the plan settings are set such that computer is never automatically put to sleep.
16. Check for Updates in Resyn
An active Internet connection is required to check for available updates. Go to the Design System | Options
screen and click Check for Updates Now.
Page | 19
In the event that the Resyn Installer reports an error, or does not update, then click Clear Downloaded Updates to
clear the files. Close and reopen Resyn and it should automatically then check for updates and install them.
17. Upgrade dSPEC Firmware
Go to the Administer | Firmware view. Click Update Firmware on the dSPEC to update.
Page | 20
Follow instructions on screen. The dSPEC will restart and pause for long periods of time during the upgrade
process.
18. Verify the Resyn Computer Meets Minimum Requirements
Community recommends using Windows Firewall and at most one other antivirus software. Multiple security
suites with multiple firewalls and antivirus programs fighting each other can prevent Windows from allowing network
connections and are not supported.
Resyn requires the following minimum configuration.
• A Windows® 8, Windows® 7, Windows Vista®, or Windows XP® SP3 PC or compatible machine such as an
Apple Mac® running Windows under Bootcamp, Parallels®, or running another VM (Virtual Machine)
application. In order to run Resyn on Virtual Machine Software such as Bootcamp, VMware® Fusion or
Parallels, your computer’s Ethernet connection may need to be bridged to the Virtual Machine. For help
with configuring your system you can contact our Technical Applications Group for assistance.
• Intel Pentium 4 CPU or better
• CPU speed of 1.0 GHz or faster
• 512 MB of RAM or greater (1 GB recommended)
• Hard drive space required for Resyn: 20 MB. Additional space required for .Net 4.0 CP: 600 MB for 32 bit; 1.5
GB for 64 bit
• Display resolution of at least 1024 x 768
• Network Interface Card (10/100/1000 Mbps)
• Operating System (OS): Windows 7 (64 or 32 bit), Windows Vista (64 or 32 bit), or Windows XP SP3 (Service
Pack 3) or greater (64 or 32 bit)
