2.8.3 REQUIRED CONDITIONS TO SET UP AND RUN XNET
1. All systems on the network must be XT[2] Series Servers, XFile[2] or
XF[2], XStore[2] or XHub[2].
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 XT[2] system with a
software version that is not compatible with the network server.
4. The following parameters must be similar on all systems :
a. SDTI Speed (usually 540Mbps or 1485Mbps, from Hardware
Configuration menu)
b. Number of clips
5. Network Type must be set to “Server” on 1 XT(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 XT system 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 XTs must be connected with a good quality BNC 75Ohm cable to
form a closed loop. Connect the SDTI OUT connector of the first XT to
the SDTI IN connector of the second one, etc until the loop is closed by
connecting the SDTI OUT connector of the last XT 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:
