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 IP
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:
Direct
Automatic IP is
preferred.
Static IP can work too.
Continue
Troubleshooting
Connections on page 5.
The computer running Resyn is connected directly to dSPEC with one Ethernet
cable.
Indirect
Automatic IP is
preferred.
Static IP can work too.
Continue
Troubleshooting
Connections on page 5.
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.
Remote
Automatic IP will not
work.
Static IP is required.
For help with setting up
or troubleshooting
remote connections
please refer to the
Remote Management
Manual via the Resyn
Help menu.
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
Wikipedia: https://en.wikipedia.org/wiki/10/100/1000.

After the symptom is resolved go no further. Instead, if you are trying to connect, begin again at 1 Try to connect on
page 7. If further assistance is required please refer to step 19. Contact Community on page 20.
Table 1 Symptom, Possible Cause, and Suggested Steps to Resolve
Symptom
Possible Cause and/or Suggested Steps to Resolve
dSPEC(s) do not appear in Resyn.
This occurs when Resyn cannot find dSPEC(s) via IP. There
could be a power, network cabling, IP configuration problem,
automatic IP addresses did not yet resolve, or dSPEC firmware
is older than 1.24 and dSPEC was powered on before Resyn
was started. If a dSPEC is found after cycling power on it the
firmware many need to be upgraded as indicated below.

17. Upgrade dSPEC Firmware
Resyn reports a dSPEC is not on the
local network.
This typically occurs between the Resyn computer and dSPEC
when one has an automatic IP address and the other has a
static IP address. Windows uses automatic IP by default when
no DHCP server is available, however sometimes the
computer’s IP address was set to a static IP address to talk to
some other manufacturer’s gear. It can also occur when
unplugging a cable from a network that uses DHCP and
plugging it directly into dSPEC which uses APIPA.
5. Cycle power on the dSPEC(s) (turn off amps first)
7. Restart the Resyn computer
8. Verify IP Addresses
Resyn reports device already
connected.
Only one copy or instance of Resyn can connect to a dSPEC at a
time. Perhaps someone else is connected to the dSPEC from a
different computer running Resyn.
Suggested steps.
- First verify someone else is not using the dSPEC. If no one
else is:

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).
Table 2 Audio Settings Transferred During Connect
Connect Choice Settings Transferred
Settings in the Actual dSPEC(s) replace settings on
*Virtual dSPEC(s) defined in Resyn.
Continue with transferred the two become one.
Load and Connect.
Settings in *Virtual dSPEC(s) defined in Resyn
replace settings on Actual dSPEC(s).
Continue with
Store and Connect on page 9.
* Within Resyn a Virtual dSPEC is a graphic representation of an Actual dSPEC. A Virtual dSPEC has all of the same
audio settings as an Actual dSPEC. A Virtual dSPEC can be defined and configured without having Actual dSPEC
hardware present. Upon connection, a Virtual dSPEC is paired with an Actual dSPEC. After the settings are transferred
the two become one.
Load and Connect
Open Resyn. Choose Connect | Load from dSPEC(s).

Page | 8
Resyn will find the Actual dSPEC(s) on the network. Click Add on the ones you want to add to the venue project.
Choose Load.
Resyn will show the dSPEC(s) on screen. After loading the settings from the dSPEC(s) is complete Resyn will show
each dSPEC as “Connected” with its heartbeat LED blinking. You may need to scroll up or down to see all the dSPEC(s).
Please refer to the Reference Manual for dSPEC and Resynfor an explanation of how to use dSPEC and Resyn.
