Page 4: About This Manual
This section gives an overview of the NetLink system and explains how it works in various usage scenarios. • NetLink Front End Unit This section describes how to connect and set up the NetLink front end unit. • Getting Started and Basic Operation This section is a quick-start guide, designed to help the user get a NetLink system going. -
Page 5: Introduction
Introduction The NetLink product allows domo equipment to be connected to IP networks. In its basic form the NetLink can be connected to the output of any standard domo transmitter or receiver, and translates the signal into a streaming video service. NetLink can be set to stream at rates suitable for either private or public networks. -
Page 6: Warranty And Support
Warranty and Support 4.1 Warranty Cover domo offers a 12 month standard product warranty. During this period, should the customer encounter a fault with the equipment we recommend the following course of action: • Check the support section of the website for information on that product and any software/firmware upgrades. -

It can also be used with domo SOLO4 links, as in the diagram above. In this version the camera is local to the NetLink unit, therefore a PTZ camera can be used and plugged directly into the NetLink, without the need for a telemetry link. -
Page 9: Netlink User Interfaces
6.2 NetLink User Interfaces The NetLink applications allow users to interact with remote front end units from their computers or portable devices. Before any interaction can take place, the user has to log in to the remote unit (this is explained in detail in later sections). - Page 10 The NETEPLAY version is the fully-featured NetLink user interface. It runs on Windows XP and Vista computers, and gives access to the full set of NetLink features. It is designed to look familiar to users of standard video surveillance systems. The screen can be split into multiple windows, and each window can play a live stream or a downloaded one.

Page 11: Netlink Systems
Mobile NetLink and User via 3G In this example the NetLink unit is connected to the internet via 3G, so it can be installed in a moving or parked vehicle, or any location where ADSL lines are not available. -
Page 12: Netlink Modes
Private Network Mode In this mode, the NetLink unit behaves like a domo NetStream unit: It multicasts a full quality, full frame rate audio/video/data stream onto a private network. The multicast can be received and played back on a PC using the domo software decoder, or it can be output as composite/ S-Video, using the domo IP Hardware Decoder. - Page 13 Client mode is also useful when a single live stream needs to be viewed simultaneously by multiple users. In this case the server receives the live stream from the NetLink, and forwards it to as many users as its bandwidth will allow.

(NETEPLAY or NETSMART), Software Decoder (NETSWDR), or Hardware IP Decoder (NETIPHW). The NetLink unit is self-cooling; however it should be mounted in a ventilated environment. Forced air cooling is not required. Adequate clearance on either side the receiver (5cm) should be allowed for ventilation. -
Page 19: Powering On The System
For thumbnail streaming on public networks, the external modem should act as a DHCP server to give the appropriate IP address to the NetLink unit. If the modem acts a router, appropriate routes must be set up to allow NetLink traffic though. -
Page 20: Getting Started And Basic Operation
This procedure can also be followed to restore a NetLink to a working state after the wrong settings have been applied. This set up procedure is carried out with both the NetLink and the PC running the NETEPLAY application connected to the same network. -
