Control systems with Ethernet and Cresnet capabilities can function as an Ethernet
master and a Cresnet master simultaneously.
Ethernet Slave
A control system operating in the Ethernet slave mode operates as an Ethernet device
and makes its built-in ports (except for Ethernet and Cresnet) available to a master
control system. While operating in the Ethernet slave mode, any program that is
loaded into the control system will not run. When operating in the Ethernet slave
mode, the control system can address any installed hardware, but it cannot address
Cresnet or Ethernet network devices.
Slave control systems with Ethernet and Cresnet abilities can be configured to
operate as either Ethernet or Cresnet slaves, not both. If a slave system is configured
as both, it will operate in the Cresnet slave mode.
Master-Slave Operating Guidelines
Following are some general rules for master-slave configurations:
• A slave device cannot have its own network (Cresnet or Ethernet).
• 2-Series slave systems can only be controlled by a 2-Series master system.
• A control system with both Cresnet and Ethernet capabilities can operate as
an Ethernet master and a Cresnet master simultaneously.
• A control system with both Cresnet and Ethernet capabilities can be either
an Ethernet slave or a Cresnet slave. It cannot be both simultaneously. If it
is configured as both, it will operate in the Cresnet slave mode.
• A slave can be controlled by only one master control system. Only one
Cresnet master can exist in a network. Multiple Ethernet master systems can
exist in a network. However, an Ethernet slave only responds to one master.
• Any program loaded into a control system will not execute while a control
system is in the slave mode.
• While operating in the slave mode, Crestron Toolbox functions such as
firmware upgrades can still be performed. Passthrough mode operations
from Viewport can also be used on the slave control system.
NOTE: All control systems ship in the master mode except for the C2N-DVP4DI
and CNX-DVP4, which ship in the Cresnet slave setting.
