Connecting consoles for a True Tracking Backup system

Any True Tracking Backup configuration with grandMA components may only be connected via a EtherNet

communications network. The grandMA consoles currently support two different hardware types of transmission

media.

0 Base-2 EtherNet

EtherNet with 10 Base-2 connection media (also known as Cheapnet) has lost its importance in todays

networking technology. Nevertheless as 10 Base-2 systems are very easy to configure and they do not require

additional networking nodes or hubs they might be used to easily link two or more grandMA consoles. As the

built-in EtherNet card of the grandMA console autosenses the used connection media there is no need to

configure the consoles hardware at any time.

The connection cable used for 10 Base-2 EtherNet is a 75 ohm coaxial cable (RG-58U) with male BNC connectors

on both ends. The maximum cable run is up to 180 metres from end-to-end.

BNC cable to be used for 10 Base-2

All connections to any kind of networking units (like consoles, PCs or Hubs) require the use of a T-connector,

which has to be connected to the BNC output of the console. Extension cords are not permitted.

T-connector to be used with10 Base-2 network nodes

Any connection cable used for 10 Base-2 EtherNet has to be terminated on both ends with 75 ohm resistors. If

these resistors are disconnected or of the wrong value no network operation will be possible.

Line termination on 10 Base-2 network

10 Base-2 EtherNet can be used for grandMA master/slave connections when no ArtNet DMX-Nodes or other

distribution equipment is planned to be used. For longer cable runs or distributed networks 10 Base-2 EtherNet

is not recommended any more.
