Principles of Operation

Although you may have used DrayTek switches for regular networking applications

previously, the V1281 is different because it's designed for switching A/V.

Sources and Outputs

Throughout this Quick Setup Guide and also within the V1281's admin interface we

will refer to sources and outputs.

• A source is any device which is providing a video or audio output – most

commonly a DVD/Blu-ray player, a satellite receiver or other set-top box or a

CCTV system.

• An output is what you'll be watching or listening on, such as a TV, a projector

or an amplifier/receiver.

Also, in our setup guides and in the switch GUI we will generally colour code

in red

and

outputs in green

HDMI vs. Ethernet Cabling

Like any Ethernet switch, the V1281 has RJ-45 sockets on the front, not HDMI.

Although native HDMI switches do exist, cable lengths are limited and the cables

themselves are more costly and complex to wire up.

Using Ethernet means you use low cost CAT5e (or higher) cable which often already

exists in a location. If you use fibre optic cable, Ethernet can carry for many

kilometers if needed; the VigorSwitch can support up to 4 SFP fibre modules.

Using CAT5e also means that the V1281 is very scalable – you can add as many or few

sources or outputs as you need up to the maximum number of ports whereas with a

native HDMI switch, it will have a fixed number of ports, which you pay for whether

you need them or not. With the V1281 your AV signals can also share the network or

networking infrastructure with your data networking for PCs or other devices.

to aid with illustration and clarity.
