1 Safety
Prior to installing or operating products, always read the Important Safety Instructions which are available as a separate multilingual document: Important Safety Instructions (Safety_ML). These instructions are supplied together with all equipment that can be connected to the mains supply.
Safety precautions
Some of the DICENTIS Conference System products are designed to be connected to the public mains network.
To avoid any risk of electric shock, all interventions must be carried out with disconnected mains supply.
Interventions with the equipment switched on are authorized only when it is impossible to switch the equipment off. The operation must only be performed by qualified personnel.
Old electrical and electronic appliances
Electrical or electronic devices that are no longer serviceable must be collected separately and sent for environmentally compatible recycling (in accordance with the European Waste Electrical and Electronic Equipment Directive).
To dispose of old electrical or electronic devices, you should use the return and collection systems put in place in the country concerned.
Class A equipment (commercial broadcasting equipment)
This equipment is for professional (Class A) electromagnetic compatibility equipment. Seller or user should pay attention to this point. It is intended for use outside the home.

3 System installation overview
It is advisable to participate in the DICENTIS Conference System training before you install, configure, prepare, and operate a DICENTIS Conference System.
The DICENTIS Conference System is an IP based conference system which runs on an OMNEO compatible Ethernet network. It is used for distributing and processing audio, video and data signals.
The DICENTIS Conference System can be quickly and easily configured as a daisy chain configuration or as a star configuration:
–Daisy chain configuration: Uses dedicated cabling, consisting of CAT 5e cables including two additional power conductors (see Typical system setup, page 8).
–Star configuration: Each DICENTIS device is connected with an individual standard CAT 5e cable. An Ethernet switch is also required for providing Power over Ethernet (PoE).
Notice!
When Power over Ethernet is used, DICENTIS devices cannot be daisy chained. Please use unshielded cable for the DICENTIS discussion devices.

Tab. 3.1: Nodes count of DICENTIS equipment
An ARNI (Audio Routed Network Interface) is used to increase the number of DICENTIS devices on a single subnet and to connect multiple DICENTIS system subnets. If more than one subnet is required, two types of an ARNI must be used.
–OMN-ARNIS (ARNI S OMNEO interface): The ARNI S is required for increasing the system size above 100 DICENTIS devices. It supports up to 450 DICENTIS nodes in its subnet. It also acts as a DHCP server in its subnet.
–OMN-ARNI E (ARNI E OMNEO interface): The ARNI E is required for increasing the system size above 450 DICENTIS nodes. It supports up to 450 DICENTIS nodes in its subnet. It also acts as a DHCP server in its subnet. It can connect up to 40 subnets, each with an ARNI S.
Defining subnets and subnet masks
A subnet is a logical, visible subdivision of an IP network. The number of DICENTIS devices that can be in the same subnet depends on the subnet mask.
A standard class C subnet (255.255.255 or /24) can contain 254 IP addresses. Some DICENTIS devices have 2 IP addresses. For this reason, Bosch advises to use 255.255.252.0 (or /22) as a subnet mask. This allows you to have 1018 IP addresses. The following table lists the number of IP address per DICENTIS device in a DICENTIS Conference System.

–The max age timer should be set to 22 when RSTP is used for cable redundancy to prevent a defective cable or powering switch from influencing the system.
–Each time data hops from one switch to another, the age is increased by one. This timer can be reached or exceeded, because a daisy chain can be used to loop through the DICENTIS devices.
–This timer (or restriction) cannot be reached when there is no cable redundancy. This is because the power limitation will be reached before the max age restriction is reached.
–The timer can be reached when:
–you use cable redundancy.
–the system is incorrectly wired.

Multi subnet DICENTIS Conference System
The following figure illustrates a typical multi subnet DICENTIS Conference System with a total of 1200 DICENTIS devices.
–The system is divided over four (4) subnets, where two (2) subnets having a maximum of 400 DICENTIS devices and an OMN-ARNIS are connected.
–The system has one OMN-ARNIS installed in the first subnet with a maximum of 400 DICENTIS devices connected (Note that only one OMN-ARNIS is allowed within a multiple subnet DICENTIS Conference System).
–Subnet four (4): When using multiple subnets, make sure that all cameras needed to capture video of the seats are all connected to the same subnet.

System installation design and planning |
|
Before you start to install system devices and connect system cabling, you should make a system design and planning:
–Familiarize yourself with the product and system capabilities.
–Make a cable (connection) plan:
–Calculate the system network cable length.
–Calculate the system power consumption.
–Calculate the required power capacity of the system.
Notice!
The DICENTIS Conference System uses the RSTP protocol when redundant cabling mode is enabled. If the DICENTIS Conference System needs to be connected with the locally present network, please consult the local IT department before continuing with the installation design.
Notice!
Make sure that the cable lengths and power consumptions do not exceed the specifications. Not doing so will result in malfunctioning at any moment of the DICENTIS Conference System and products.
4.1System capabilities
The capability of the DICENTIS Conference System and DICENTIS products depends on:
–The lengths of the system network cables.
–The number of connected devices.
–The system power supply capacity.
Cable length
System network cables (DCNM CBxx-I) lengths (2, 5, 10 or 25 m) have a direct effect on the available power supply capacity. The longer the system network cable, the less power supply capacity is available to drive the connected devices. Therefore, choose the lengths of the system network cables carefully.
Notice!
Custom network cables must never exceed the maximum Ethernet specification of 100m (IEEE 802.3ab).
Keep your network hierarchy as flat as possible. This means having as few levels as possible. It is recommended not to exceed 7 levels. See the following example: 1: 1st level = Root switch, 2: 2 nd level = switch, 3: 3 rd level = switch.

|
Power supply capacity
The total system network cable length and connected devices determine the required power supply capacity. The power within the DICENTIS Conference System is supplied by:
–The Audio processor and powering switch and the Powering switch, or
–Off the shelf PoE Ethernet switches.
Calculation tool
The calculation tool can be used to calculate the total power capacity of the system. This makes the design and planning of the DICENTIS Conference System easier. The calculation tool uses the power consumption of the devices and the system network cable lengths to calculate the needed system power supply capacity.
The calculation tool is on the DVD supplied with the Audio processor and powering switch and is part of the DICENTIS software DCNM.iso file. The DCNM.iso file can be downloaded from the Bosch website at: https://licensing.boschsecurity.com/software
