24 +If devices in App Mode are being used as part of a networked system running a custom program, then any configuration changes made through the Zūm App should be made while the device is disconnected from the processor.

23 -Using ZUMNET-JBOX-* devices in CNET Mode is only possible on a [[networked system with a custom program>>WebHome||anchor="HNetworkedwithCustomProgram"]]. While in CNET Mode, ZUMNET-JBOX-* devices suspend any local logic and act as a "dumb" Cresnet-to-Ethernet bridge with a built-in load controller. Instead of receiving communications from Zūm Link devices and deciding what each device should do, the ZUMNET-JBOX simply passes the information on to the control processor to do all the thinking. While in CNET Mode, ZUMNET-JBOX-* devices cannot be connected to through the Zūm App, and any attached ZUMLINK-KP or ZUMLINK-OCC-* sensors will not work without the processor.
28 +Using ZUMNET-JBOX-* devices in CNET Mode is only possible on a networked system with a processor that is running a custom program. While in CNET Mode, ZUMNET-JBOX-* devices do not process any local logic and cannot be connected to through the Zūm App in order to be configured. This is because while in CNET Mode, ZUMNET-JBOX act as a "dumb" Cresnet-to-Ethernet bridge with a built-in load controller. They report all Zūm Link traffic back to the control processor and do not do any "thinking" on their own. Any attached ZUMLINK-KP or ZUMLINK-OCC-* devices will not work without the processor if the ZUMNET-JBOX is in CNET Mode.

25 -The benefit of using CNET Mode with a custom program over App Mode is that it allows for the control processor to have direct control over all hardware in the system. This enables a custom program to meet a significantly wider range of sequences than App Mode. Additionally, CNET Mode offers increased security over App Mode as it is not possible to connect to a device with the Crestron Zūm App while it is in CNET Mode.

27 -The main drawbacks of using CNET Mode are the added hardware and installation costs that come with requiring a networked system and custom program. Systems running on outdated firmware have the additional drawback of losing all local controls in the event that connection to the control processor is lost, but this risk has been addressed with the introduction of the [[Zūm Mode Auto Switch>>WebHome||anchor="HZ16BmModeAutoSwitch"]] feature.
32 +The two main drawbacks of using CNET Mode are the requirement for a networked system with a custom program and the loss of local control in the event that connection to the control processor is lost, however the introduction of the Zūm Mode Auto Switch feature in .puf firmware v1.04.05 (device firmware v1.004.00005) has eliminated this second drawback by enabling devices to automatically switch between CNET and Zūm Modes when connection to the processor is lost or regained.

33 33  Zūm Mode Auto Switch is a feature introduced in November of 2022 with .puf firmware v1.04.05 (device firmware 1.004.00005). This feature is intended to address concerns that arose from projects using custom programs with ZUMNET-JBOX-* devices in CNET Mode. Previously, if a device in CNET Mode lost connection to the processor, then it would be impossible to maintain any sort of control over the lighting. With Zūm Mode Auto Switch enabled, a ZUMNET-JBOX running in CNET Mode will automatically switch to App Mode and process local logic in the event that it loses connection to the processor.

Crestron ships all ZUMNET-JBOX-* devices with a default PIN that is intended to be changed during commissioning, however there is no guarantee that the technician who configured the Zūm Wired hardware knew or remembered to do this.

63 -Designs for Zūm Wired systems are broadly categorized as either "standalone" or "networked" designs. Both standalone and networked systems should be designed with one ZUMNET-JBOX-* per room or logical control space connected to a number of ZUMLINK-* devices within that same space. In standalone systems, there is no central control processor and no Zūm Net cabling connecting rooms to each other, which reduces the cost and complexity of the installation but also comes with some of its own limitations. Networked systems, by contrast, do have a control processor which provides centralized control of the entire system. Zūm Net cabling is used to daisy-chain ZUMNET-JBOX-* devices together and then connect them to the lighting network for control by the processor.
