5 -DIN-CENCN-2s are Cresnet-to-Ethernet bridges which convert data over the Cresnet bus into high-speed Ethernet traffic. This helps avoid issues with bandwidth over the Cresnet bus for jobs which have a large number of Cresnet devices, as well as allowing for additional power supplies to provide power Cresnet devices.
5 +DIN-CENCN-2s are Cresnet-to-Ethernet bridges which convert data over the Cresnet bus into high-speed Ethernet traffic. This helps avoid issues with bandwidth over the Cresnet bus for jobs which have a large number of Cresnet devices, as well as allowing for additional power supplies to provide power Cresnet devices. They are analogous to [[CEN-GWEXERs>>doc:SHOWRUNNER™ Setup Guide.SHOWRUNNER™ Installation Guide.SHOWRUNNER™ Installation and Network Setup.CEN-GWEXER Setup.WebHome]] for Crestron wireless systems.

7 7  For SHOWRUNNER™ installations, the IP address of the DIN-CENCN-2 does not matter as long as it is in the same range as the processor and does not conflict with any other devices on the network. Instead, DIN-CENCN-2s are identified to the processor via their IP-ID. Note that which Cresnet devices are landed at each Net of each DIN-CENCN-2 matters, and if devices are moved between Nets or between DIN-CENCN-2s then the configuration will need to be updated (see below). Chief Integrations typically provides an SRTakeoff.xlsx spreadsheet with an IP Table tab that lists all the DIN-CENCN-2 IP-IDs in the program. If no takeoff is provided, then the processor's IP table can be checked by running the ##ipt -t ##command from the processor after the configuration is loaded. DIN-CENCN-2's will typically have IP-IDs in the "##Dx##" range.

28 28  In SHOWRUNNER™, which Net each Cresnet cable is landed on is important. Each DIN-CENCN-2 is firmware limited to a maximum of 25 Cresnet devices per Net, and which CENCN-2/Net each device is on is tracked in the configuration file. If devices are moved between DIN-CENCN-2s or moved between Nets on the same DIN-CENCN-2, then the configuration file must be updated. Every device in the configuration has a ##"DeviceHostId"## (the host DIN-CENCN-2's IP-ID) and a ##"DeviceHostBranch"## (the Net of the DIN-CENCN-2) associated with it.
