ZUMNET-JBOX Setup

ZUMNET-JBOXs in SHOWRUNNER™

ZUMNET-JBOXs are part of Crestron's latest Zūm Wired system, acting as an Ethernet-to-Zūm Link bridge to convert between Ethernet and Zūm Link data traffic. 

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.

IP Configuration

Typically, each DIN-CENCN-2 will need to be initially configured via USB, unless their MAC addresses are already known and the lighting network has a DHCP server (either by running DHCP server software on your computer, or if the processor has a control subnet or is running the SHOWRUNNER™ DHCP Server). 

Whether connected to the DIN-CENCN-2 via USB or Ethernet, the process to configure the static IP addresses is the same:

  • Open Text Console in Toolbox and connect to the DIN-CENCN-2
  • Run the following commands to configure the DIN-CENCN-2's IP settings (example is for a 10.0.0.0/24 subnet, with a CENCN-2 IP address of 10.0.0.12, a CENCN-2 IP-ID of D1, a processor IP address of 10.0.0.10, and a hostname of CENCN-L1)
    • Disable DHCP: dhcp 0 off
    • Set IP address: ipa 0 10.0.0.12
    • Set IP subnet mask: ipm 0 255.255.255.0
    • Set default gateway: defr 0 10.0.0.1
    • Update IP table: addm D1 10.0.0.10
    • Set hostname: host CENCN-L1
    • Reboot the DIN-CENCN-2: reboot
  • Repeat for all DIN-CENCN-2s on the job

Moving Cresnet Devices

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.

When moving devices between Nets or between DIN-CENCN-2's it is important to keep in mind several things:

  1. Cresnet IDs ("DeviceConnectionId") cannot conflict with the Cresnet ID of any other devices defined in the config on the same host ID and branch
  2. Cresnet IDs must be in the hexadecimal range 03 to 1B
  3. Any children devices (such as NS occ sensors, photocells, GLPPA-KP keypads, etc.) must also be moved. If the parent Cresnet ID is changed then the children IDs must also be updated
  4. If devices are moved from a DIN-CENCN-2 to be landed directly on a processor (or landed on a DIN-HUB on a processor), then the device host ID should be null and the host branch should be 0
