the new Cresnet ID value. The Program Info section is not displayed as the slave
control system does not have a program that is running.
Ethernet Master-Slave Modes
The contents of a control system’s IP table and SIMPL Windows programming
determine whether a control system is operating as a master control system or a slave
device. If a control system’s IP table entry lists a “master” device, the control system
is operating in the Slave mode to the master control system listed in the IP table. For
more information on IP table entries, refer to the latest revision of the Crestron
e-Control
®
Reference Guide (Doc. 6052) which can be downloaded from the
Crestron website.
Use Crestron Toolbox to make changes to a control system’s IP table.
To view a control system’s IP table, establish communication with the control
system as described on page 5 and select Functions | IP Table Setup… to open the
“IP Table” window.

Ethernet Master Mode
To designate a control system as an Ethernet master, there must be no “master”
entries in the control system’s IP table. Removing a master entry automatically
configures a control system as an Ethernet master when it reboots (unless it is also
configured as a Cresnet slave). Refer to the previous diagram for a sample IP table of
a master control system.
The IP IDs listed above can represent Ethernet devices and Ethernet slave devices.
Ethernet Slave Mode
To designate a control system as an Ethernet slave, there must be an entry for a
“master” control system in the Ethernet slave’s IP table. Once a master control
system is listed in the slave’s IP table, other entries are ignored, as a slave device
cannot have its own network. Refer to the following diagram for a sample IP table on
a slave control system.
