Server Setup

Synchronizing via an External Sync Generator

An external sync generator synchronizes all connected devices. To inte-

grate it in the multi-device setup perform the following:

y Connect all video channels with their sync inputs to the external

sync generator.

y If appropriate, alter the sync settings of all connected channels via

their sync settings (see section “Sync Settings” on page 4-9).

Once the external sync generator is active, the synchronization will take

place.

Synchronizing from Within the Multi-device Setup

You can also synchronize the channels from within by selecting one of

them as the sync master. For this perform the following:

y Select one channel that shall act as the sync master.

An analog sync signal can be transmitted through the sync in- and out-

puts, a digital sync signal through the SDI ports. You can use either a

distributor to connect the slaves’ sync inputs to the master’s sync out-

put, or build a chain where the master’s sync output is connected to the

sync input of the first slave, whose sync output is connected to the sync

input of the second slave, and so on. With the termination switch at the

reference inputs of the video channels, the chain can be built up with

T-junction connectors at each reference input connector (except the

first and the last one). Then switch off the termination of the reference

inputs at the channels between the first and the last one.

y Connect the other video channels which act as sync slaves to the

sync master via their sync connectors.

y If appropriate, alter the sync settings of all connected systems via

their sync settings (see section “Sync Settings” on page 4-9).

The setup for the synchronization from within is now complete and the

synchronization will take place.

2.4.3 Notes on the Multi-device Operation Mode

This section provides some notes on how to use the multi-device oper-

ation mode:

The sync master does not have to be identical with the master

of the multi-device operation. You can choose any of the video

channels as the sync master.

When building a sync chain, cable elapse times may lead to

synchronization problems. In such a case you have to use an

external sync generator.
