Introduction
This guide is intended to outline the requirements, best practices and preferred methods of implementing Crestron
devices on enterprise level networks. Focused on the concerns of the IT professional, Crestron is dedicated to providing the most accurate and pertinent information. If, after reading this document, you still have concerns about
deploying Crestron devices on your network, please contact True Blue Support at 1-888-CRESTRON.
What is a Control System?
A control system is an appliance grade network-based device designed to control disparate devices and link them
together over an IP network. It issues commands and gathers data to and from other devices based on user driven
and automated events. Typically driving classroom and boardroom AV systems, a control system turns on the
display and sets the correct input based on the press of a button on a touch screen, remote control or button panel
(keypad). Control systems can even interface with the lighting and HVAC systems so when “PC” is selected, the
lights dim to an appropriate level for viewing computer images.
The power behind Crestron control systems is the ability to custom program or configure them. Any single button
press or collection of data can trigger any other number of events. The possibilities are truly endless.
Why is it on my Network?
Traditionally control systems have interfaced with devices via IR, RS-232, closed contacts and variable voltage.
The natural progression over the past years has moved toward IP-based communication. Many devices have
implemented IP protocols for control, monitoring and management mainly because IP is more common and cost
effective to integrate.
Crestron systems were the first control systems to implement IP communication almost 15 years ago. Today,
Crestron offers some of the most advanced IP devices in the AV and lighting control industry. Crestron systems can
be controlled, maintained, and monitored from anywhere there’s an Internet connection. This greatly enhances the
ability to update and troubleshoot systems without having to be physically on site.
Proven and Trusted
With installations in facilities of some of the technology leaders of the world like Microsoft® and Cisco®, Crestron
control systems are suited for the most mission-critical and secure environments. After following the guidelines in
this document, you can rest assured that Crestron devices will pleasantly coexist on your network.

Crestron IP Considerations Guide
Planning a Network with Crestron Devices
Before deploying a Crestron system on any network, it is important to consider the guidelines defined in the following sections. While there are many ways of configuring enterprise networks, these best practices have been found
to be the most efficient and successful for Crestron devices.
Isolate The Network
Crestron devices should exist on a network separate from other device traffic. Other network activity can impact
the response time of Crestron devices and disrupt the user experience.
Unlike most any other application communicating over your LAN/WAN, Crestron users expect instant control and
feedback. To ensure constant connection and accurate feedback, proprietary Crestron control communications
uses a heartbeat packet. Loss of round trip heartbeat packets indicate unreliable connections. This strict connectivity requirement ensures user confidence but is very latency sensitive.
Crestron recommends setting up all Crestron devices on a dedicated (Crestron only) VLAN so that unnecessary
broadcast traffic does not interfere with the time sensitive packets between Crestron devices.
Deploying Crestron devices on a dedicated VLAN also enables you to provide network access control to them (in
addition to username/password authentication, available on Crestron control systems).
VLAN Configuration
Whenever possible, all Crestron devices should be separated into their own VLAN. This will allow smoother operation of the control network and help manage the infrastructure—resulting in an overall better user experience.
The following steps should be taken to ensure that Crestron devices can be managed effectively:
• If Crestron devices reside on multiple VLANs, static routes should be set up between
VLANs on a router.
• DHCP requests should be forwarded to the appropriate VLAN with a DHCP server.
• Crestron ports should not be blocked for proper operation. A list of commonly used
Crestron ports is available on page 3. For detailed information regarding what
port numbers are required, please consult the appropriate device manual.
• Some devices allow for streaming media content from the Internet. These devices
should be allowed to connect to the Internet if streaming is desired.

IP Addressing
In general, best practices are to assign Crestron devices static IP addresses. Communication amongst Crestron devices relies on IP addresses remaining the same. In large corporate or university environments, static or reserved
DHCP is recommended to aid in managing devices.
In certain cases, like with DigitalMedia products, static mode may be preferred over DHCP. Please see “DigitalMedia™ Network Considerations” on page 6 for more information.
IPv6
All Crestron control systems can exist on an IPv6 network. For a list of Ethernet compatible control systems, see
Appendix A on page 14.
Hostnames/Domain Names
Crestron best practices are to configure DNS and DHCP servers to allow hostnames to resolve via option 81 and
option 12.

For the IT Professional
Security
The following security information is centered around Crestron control systems. For a list of control systems, see
Appendix A on page 14.
Security Setup
Always define an administrator password – this guarantees that only authorized personnel can make changes to
the configuration of Crestron equipment.
Enable SSL – to ensure that passwords are not sent clear-text over the network.
Have the Crestron programmer add passwords/passcodes to those sections of the user program that are related to
configuration of third-party devices.
Firewall Setup / Communication Across Multiple VLANs
Crestron systems can be controlled remotely. For example, an iPad® running Crestron Mobile Pro® G on a 3G cellular network can send commands to the control system to adjusts the lights. In another scenario, a centrally located
RoomView™ server requires communication across multiple networks in order to communicate with all rooms.
These applications require the following ports to have access to the outside network:

Crestron IP Considerations Guide
DigitalMedia™ Network Considerations
It is important to know that most Crestron DigitalMedia (DM) devices are Ethernet devices. Ethernet traffic due to
DigitalMedia devices is relatively low. The custom control system program that ties together the DM system will
dictate how much bandwidth is needed.
DigitalMedia Certified Designers and Engineers
Every Crestron DigitalMedia system should be designed by a DigitalMedia Certified
Designer (DMC-D) and commissioned by a DigitalMedia Certified Engineer (DMC-E).
If you are unaware of a DMC-D or -E being involved with the deployment of the DM
system on your campus, please contact you system installer.
Only Crestron certified engineers ensure that your system is properly installed and configured to Crestron
standards. The information in this guide is intended to explain basic DM IP addressing considerations. Consult
with your DMC-E if you have questions.
DigitalMedia System Topology
Each DigitalMedia link (connection between two DM devices) carries Ethernet embedded inside so that no additional wiring is needed to provide network connectivity for third party Ethernet products installed at the endpoints.
Interconnected DM devices only need a single point (typically the main switcher) to be connected to the LAN in
order to provide Ethernet to all devices in the system. To facilitate this, Crestron DM devices have integrated managed Ethernet switches and an exposed Ethernet port.
NOTE: A DM endpoint refers to any DM transmitter or roombox (receiver).
In the below scenario, Ethernet connectivity is provided to all DM devices and third party devices from the single
LAN connection at the DM-MD8X8. This eliminates the need to run extra wiring to each location to provide Ethernet
connectivity.

DM Link
The main Ethernet uplink to a DM system occurs at the DigitalMedia switcher. The following switchers have
10/100/1000BaseT auto-negotiating uplink ports:
• DM-MD8X8, DM-MD16X16, DM-MD32X32
6
For the IT Professional
The following switchers have 10BaseT/100BaseTX auto-negotiating uplink ports:
• DM-MD6X1
Other devices in the DM family contain 10BaseT/100BaseTX auto-negotiating Ethernet ports.
Remember, DigitalMedia devices create a flat network that contains only switches—no DHCP servers or routers.
DHCP Mode
When the DM switcher is set to DHCP mode, all (addressable) cards and endpoints will also be set to DHCP mode.
Each of these DigitalMedia devices will receive an IP address from the external DHCP server located on the network.
# of IP Address
NOTE: When using DM 8G products (part numbers with the suffix “-C” or “-S”), DHCP mode will require more IP
addresses than static mode. This is because a DM 8G input or output card can be assigned an IP address (unlike
original DM CAT and fiber input and output cards—DMC-CAT(-DSP), DMC-F(-DSP), DMCO-”1”, DMCO-”2” ).

Crestron IP Considerations Guide
Addressable Device Number
An “addressable device number” refers to the physical location of a card or card/endpoint combination within
a DM switcher. This term is used when explaining how a DM switcher assigns IP addresses when in static
mode.
Static Mode
When a DM switcher is set to static IP mode, all cards and endpoints will also be set to static mode. To reduce the
amount of time needed to configure the IP addresses, DM switchers will configure the addressing for any applicable DM device (transmitter, receiver, input/output card). In DM, this IP mode can be thought of as an “automatic”
static mode. The switcher’s mode is set, and all connected devices are automatically configured. The IP addressing
scheme is detailed below:
DM device’s IP address = the switcher’s IP address + the addressable device number
It is best to set aside an IP address range to accommodate an entire switcher:

Depending on the DM system configuration, not all IP addresses in this “blocked out” range will be used.
*When more than one DM-MD6X1 is used on a network, the base IP addresses can be staggered in a way to maximize an IP address range. See Appendix C on page 16 for more information.
NOTE: A DM switcher will never configure the IP information of another switcher, even if they are interconnected
via DM.
DM-MD8X8 and DM-MD16X16 IP Architecture
Both the DM-MD8X8 and DM-MD16X16 share the same hardware architecture. Diagram 3.2 on page 9 shows
a typical switcher layout. Sample IP addresses have been inserted to demonstrate the addressing scheme.
• Input cards utilize addressable device numbers 1-16
• Output cards utilize addressable device numbers 17-32
• A DM-MD8X8 doesn’t have addressable device numbers 9-16 or 25-32, but a DMMD16X16 does
• “Automatic” static IP addressing on DM is done out-of-band and is not in any way a
DHCP server.
› It is equivalent to assigning a static IP address to each device manually.

Static Mode: DM-MD32X32 Architecture
Diagram 3.5 on page 11 illustrates the architecture of a DM-MD32X32.
Similar to the DM-MD8X8 and DM-MD16X16 architecture, the DM-MD32X32 assigns IP addresses based on addressable device numbers:
• Input cards utilize addressable device numbers 1-32
• Output cards utilize addressable device numbers 33-64
NOTE: In static mode, a fully loaded DM-MD32X32 can consume up to 65 IP addresses. It is important to set the IP
address of the switcher low enough so you don’t run out of addresses within the subnet (i.e., don’t set the IP address of a 32X32 higher than x.x.x.142 in a network with a subnet mask of 255.255.255.0).
Static Mode: DM-MD6X1 Architecture
Diagram 3.3 on page 9 illustrates the architecture of a DM-MD6X1.
Only five (5) IP addresses are needed for a maximum DM-MD6X1 system. The automatic static addressing scheme
in this switcher is similar to that of the 8X8 and 16X16 switchers. To avoid any network address conflicts, it is best
practice to block out the range of 17 IP addresses after the base IP of the DM-MD6X1. When multiple 6X1 switchers are deployed on a single network, the base IP addresses can be staggered in a way to maximize the address
use in that range. See Appendix C on page 16 for more information.
If there is a low overhead of IP addresses where this device is to be installed, use static (reserved) DHCP.
IP Addressing Recommendations For Enterprise Network Installations
In scenarios where a number of DM switchers must be managed on the same subnet, the preferred method is to
set the DM switchers to DHCP mode. By doing this, you only need to request the number of IP addresses that are
actually used by the devices instead of blocking out a larger IP address range. Static DHCP can assist with managing the DM device IP address allocation but it is not required for operation.
If your network is designed such that you cannot block out a range that large and you cannot request a large
number of IP addresses from the DHCP server then it is best to install the DM switcher behind a separate network.
See diagram below:

Best Practices for Managed Networks with Spanning Tree
If you are using a router between the DigitalMedia system and the network, this section does not apply, as the router will completely segment
the two networks. Using a router is a good solution for some customers
who are unable to ensure that the below best practices can be implemented. Another solution is to disable RSTP on DigitalMedia products
and manually break any loops. Contact Crestron Technical Support
(1-888-CRESTRON) for assistance with this.
12
RSTP is a link layer (layer 2) network protocol that ensures a loopfree topology for any LAN. Very
advanced users can find more
information on RSTP in the Cisco
whitepaper found on their website.
For the IT Professional
There is a more advanced version of RSTP called MSTP that supports multiple spanning trees on multiple VLANs.
DigitalMedia implements RSTP, but not MSTP. If you are running MSTP on your network you should ensure that the
network port that DigitalMedia is connected to only belongs to one VLAN. This is because RSTP ignores multiple
VLAN trees maintained on the MSTP end.
Managed Ethernet switches can be configured to have “edge ports” which means that no Ethernet switches can
be plugged into those ports. If you plug DigitalMedia into an edge port, the managed switch may shut the port
down because the DigitalMedia device looks like a network switch. To avoid this, ensure that the switch ports are
configured correctly where you are connecting DM products.
