66		-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 networked systems, there is also a control processor which provides centralized control of the entire system. ZUMNET-JBOX-* must be daisy-chained together with Zūm Net and then connected back to the processor. In standalone applications, there is no processor and no Zūm Net cabling connecting different rooms to each other.
	66	+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.

	68	+Networked systems can be further subdivided into those that use the default program included with ZUM-HUB4 processors and those that use a custom program, such as SHOWRUNNER™. The below sections cover in detail the advantages and disadvantages of each control paradigm.

	72	+Standalone Zūm Wired designs consist of completely independent Zūm Rooms. Each Zūm Room has a single ZUMNET-JBOX-* with any number of ZUMLINK-* devices connected to it. There is no Zūm Net connecting individual rooms, and there is no processor required. This results in a system which has a reduced hardware cost and can theoretically be commissioned and configured entirely by the electrical contractor, however there are some important drawbacks to consider.

	76	+* Reduced installation time and cost as no Zūm Net cabling is required between rooms

91		-Lorem
	82	+* As of 2/2023, ZUMNET-JBOX-* devices ship with factory settings that are incompatible with an App only startup, resulting in extra expense to configure and update devices prior to installation or extra time spent during startup to accomplish these tasks post-installation:
	83	+** ZUMNET-JBOX-* devices must be manually set to Zūm App mode
	84	+** ZUMNET-JBOX-* devices must be manually set to Primary mode
	85	+** Updating firmware with the Crestron Zūm App is not possible with out-of-the-box firmware and must be initially done through Toolbox
	86	+* ZUMNET-JBOX-* devices can only be connected to via the App if there is a ZUMLINK-KP on their Zūm Link bus
	87	+** During start-up, a technician must bring a ZUMLINK-KP to connect to the ZUMNET-JBOX in order to configure any rooms that were designed without a ZUMLINK-KP
	88	+* Firmware updates through the Zūm App can consume a large amount of time on-site
	89	+** Only one room can be updated at a time using the Zūm App, and it is not possible to do anything else while the room is updating
	90	+** The time required to update a room's firmware varies depending on the number of ZUMLINK devices in the room
	91	+* Standalone systems are limited compared to Networked systems in terms of what sequences can be met
	92	+** No scheduling capabilities
	93	+** No support for third-party integrations beyond the override contact-closure relay at each ZUMNET/ZUMLINK-JBOX and the relay output of any *-RLY model occupancy sensors
	94	+** No support for DMX control
	95	+** Any future modifications to the sequence requires reconfiguration through the Zūm App
	96	+* No support for Cresnet devices
	97	+* No cross-room control capabilities (i.e., ZUMLINK-* keypads and occupancy sensors are restricted to controlling loads that are attached to the same ZUMNET-JBOX as they are)
	98	+* No possibility for remote support or management, as the only way to connect to any of the devices is by being using the Zūm App, which requires being within Bluetooth range of the device
	99	+* Potential security concerns if the default PINs are not changed during start-up
	100	+* Not possible to provide a graphical UI (touch screen)

	104	+Networked systems are generally preferred over standalone systems for most applications. Networked systems, and in particular networked systems with custom programming, are able to meet a much wider variety of sequences compared to standalone systems. Additionally, start-up and maintenance can be simplified, and certain aspects completed remotely, compared to standalone systems.
96	96
	106	+In general, the drawbacks of any networked system are:
	107	+
	108	+* Requires additional hardware (at minimum a processor and a network switch for the Zūm Net)
	109	+* Requires additional Zūm Net cabling between rooms
	110	+* Additional start-up time required to configure the program
	111	+
	112	+All networked systems have the following benefits:
	113	+
	114	+* Some aspects of start-up can be accomplished remotely if there is remote access to the lighting network
	115	+* Updating firmware and modifying hardware configurations can be accomplished over Zūm Net
	116	+** Loadscripts can be written to simultaneous update firmware for up to 10 rooms
	117	+*** These can be run remotely if there is remote access to the lighting network, or scheduled by the technician to execute after working hours in order to free up time on-site
	118	+** Loadscripts can be written to bulk modify hardware settings (such as changing from Secondary to Primary modes) and configure IP settings (such as changing hostnames or updating IP tables)
	119	+* Able to meet a wider range of sequences compared to standalone systems
	120	+** Scheduling capabilities
	121	+** BMS/BACnet integration
