Control Subnet 

The AV3, PRO3, and CP3N have a dedicated Control Subnet, which allows for 

dedicated communication between the control system and Crestron Ethernet 

devices without interference from other network traffic on the LAN. 
When using the Control Subnet, observe the following: 

CAUTION:

 Do not connect the CONTROL SUBNET port to the LAN. The 

CONTROL SUBNET port must only be connected to Crestron Ethernet devices. 

•

 

The control system acts as a DHCP server to all devices connected to the 

Control Subnet and assigns IP addresses as needed. 

•

 

A DNS server is built in to the control system to resolve host names. 

•

 

Only connect Crestron Ethernet devices to the Control Subnet. 

The control system can also operate in isolation mode by issuing the 

isolatenetworks ON

 command. 

•

 

Devices on the Control Subnet do not have any resources on the LAN side. 

For example, if a touch screen with a SmartObjects® technology object 

requiring network access is installed on the Control Subnet operating in 

isolation mode, the object will not work. 

•

 

Devices on the LAN do not have access to any devices on the Control 

Subnet. Crestron Toolbox also does not have access to these devices 

when it is connected to the LAN. To configure devices on the Control 

Subnet with Crestron Toolbox (outside of runtime), the computer running 

Crestron Toolbox must be connected to the Control Subnet. 

•

 

Any NAT/port mapping rules that were previously created do not work 

when the control system is in isolation mode. 

NOTE:

 If the control system is running in isolation mode, Crestron Ethernet 

devices requiring Internet access should not be connected to the CONTROL 

SUBNET port (directly or indirectly) and should be instead connected to the LAN.
