1. All systems on the network must be XT2, XT2+, XS, XFile2 or XF2, XStore2 or
XHub2.
2. The SDTI advanced option code (for network client, master or server modes)
must be validated in the options list.
3. They should all be running compatible software version. A warning message is
displayed when trying to connect an EVS video server with a software version
that is not compatible with the network server.
4. The following parameters must be similar on all systems: SDTI Speed
(1485Mbps, from Hardware Configuration menu)
5. Network Type must be set to “Server” on 1 EVS video server (and only 1) on
the network. The others must be set to either “Master” (to share clips and view
others’ clips) or “Client” (to share clips only).
6. A different network number must be specified for each EVS video server that
you want to connect to the network. If the same network number is assigned to
2 different systems, the second one will not be able to connect and a warning
message will be displayed.
7. All EVS video servers must be connected with a good quality BNC 75Ohm
cable to form a closed loop. Connect the SDTI OUT connector of the first EVS
video server to the SDTI IN connector of the second one, etc until the loop is
closed by connecting the SDTI OUT connector of the last EVS video server to
the SDTI IN connector of the first one. The SDTI loop must be closed at all
times during network operation. If for any reason the loop is open, all network
communication will be interrupted and all systems will automatically switch to
stand alone mode. When the loop is closed again, network operation will
resume automatically. This problem can be avoided or limited using EVS XHub
SDTI hub.
8. The distance shown in the table below is the maximum cable length between
two active EVS servers, or 2 SDTI reclockers, on an XNet SDTI network, using
a single piece of cable between 2 servers or 2 reclockers. Intermediate
connectors, patch panels, etc., might degrade these figures. Depending on the
number of servers connected on the network, the location of the master server,
the presence or not of an XHub SDTI hub, the actual maximum values may be
higher than indicated. If longer distances between servers are required, SDTI
to Fiber converters can be used, allowing distances over thousands of meters
if necessary. EVS has validated the following SDI-Fibre converters:
