Network Components
Linn's digital media products use standard IP networking for audio distribution and control. The recommended specification for the networking products is outlined below.

Network Topology
For Linn DS/DSi systems you wish to share audio from one Linn DS/DSI (Sender) to more than five other Linn DS/DSI products you need to set the Linn Products network for Multicast filtering
We have a list of suggested etherenet products in the Multicast link.
However, we would advise that you speak to an I.T. Specialist regarding this subject to specify the etherent devices for your specific system.
If you only want to share a Linn DS/DSI to UP TO five other Linn DS/DSI rooms, this will use Unicast broadcasts.
Unicast broadcast is a small scale mode and can use the existing min 100BaseT network (devices listed below)
DHCP server
The DHCP server supplies an IP address on request from the DHCP clients. This functionality is usually provided by a router in the network.
We recommend the Netgear RP614 router for this task.
Ethernet Switch
The Ethernet switch is the connection point for all other components on the network allowing them to communicate with each other.
for large scale Davaar Multicast (>6 Linn DS/DSI in the system) you need to use Managed switches
 Recommended Ethernet Switches
|
Requirements:
- Linn recommends a dedicated, stand alone switch. Switches built into consumer grade ADSL routers, cable modems, or wireless access points tend to be compromised. The processing power of such devices is often shared between its various functions and is therefore not always capable of full performance.
- 100 Mbps or 1000 Mbps full duplex switch.
- Must be capable of fully utilising all ports simultaneously. On vendor’s specification pages this is sometimes listed under a category called the “switch backplane” or the “switch bandwidth”. (For an 8 port 100 Mbps switch, this “switch bandwidth” should be 1.6 Gbps. This number comes from 100 Mbps in, plus 100 Mbps out, times the 8 ports. For a 16 port gigabit switch, the “switch bandwidth” would be 32 Gbps. (2*16*1000 Mbps).)
Wireless Access Point (WAP)
The WAP connects the wireless control point to the network.
for Davaar Multicast (>6 Linn DS/DSI in the system)
Recommended WAPs

Linn recommends using a standalone wireless access point. Wireless access points built into switches and other consumer grade products are frequently (but not always) of a lower quality.

Requirements:
- "Enterprise grade"
- Wireless G
- Robust connection quality
and optionally
- Power over Ethernet (PoE)
Ethernet over Mains
For Davaar family systems, Ethernet-over-mains adapators may reduce the number of Rooms that can listen to a Songcast DS/DSI. refer to this explantion
These adaptors allow you to broadcast the Ethernet over Mains cabling,
If you do wish to use Ethernet over mains adapators, Linn recommends the following HomeplugAV devices
Solwise NET-PL-200-AV-PIGGY/PUSH
or
Develo 200AVeasy Starter Kit (x2)
NAS
Recommended Standard NAS
|
Stores your music on the network. See NASes.
Media Server
|
Media Server Requirements
- UPnP AV 1.0 certified
- FLAC support
and preferably
- Easy installation on the NAS
- Album Art support
The recommend Twonky media Server licence can be purhcased from | Twonky4 licence
Within the Twonky settings, put the RESCAN time to "0" (zero). If you want to add any Music create the dektop link http://your_NAS_IP:8100/rpc/rescan for the Netgear ReadyNAS or
http://your_NAS_IP:9000/rpc/rescan for other devices
This will force Twonky to only scan the media when you want it to.
Control Point
Wireless control point
The wireless control point provides the user interface (via the Linn GUI) for accessing music and controlling playback. The device can be either a UMPC (ultra-mobile PC), Internet Tablet, or a standard computer/laptop.
The Linn GUI runs on .NET 2.0
Minimum requirements:
UMPC
- 800 x 480
- 600MHz processor or greater, (800Mhz preferred)
- .NET 2.0
- Microsoft Windows XP Tablet PC edition 2005
Windows PC/laptop
- Windows XP Professional 2002
- 800 MHz processor or greater
- .NET 2.0
Specific UMPCs that Linn have tested:
Samsung Q1 (NP-Q1/V000/SUK), (NP-Q1/M02/SUK), (NP-Q1/S000/SUK), (NP-Q1/UF000/SUK) running Microsoft Windows XP Tablet PC edition 2005, Version 2002 and Service Pack 2
ASUS Notebook R2H Series, 1Gb 900Mhz Celeron M, running Windows Vista Home Premium
Specific Internet Tablets that Linn have tested:
- Nokia N800/N810 (running Media Streamer). Note: The N800 must be running Nokia's OS2008 firmware to operate with Linn's Compatibility Families of software other than Auskerry.
