2.4 Multi-device Operation Mode (Gang)
The VENICE server provides a multi-device operation mode which al-
lows for a simultaneous control of several video channels of one or
more VENICE servers.
In the multi-device operation mode one video channel is the master
that is controlled via the slave mode control window of the VENICE cli-
ent software. All other channels are slaves that follow the commands of
the master device.
This section describes how to setup and use the multi-device operation
mode.
2.4.1 Setting up and Starting the Multi-device Operation
To operate video channels in the multi-device operation mode perform
the following:
y Interconnect the video channels via their RS-422 connection ports
(see also section “RS-422 Control” on page A-1). When using an
RS-422 distributor, connect the master to the input of the RS-422
distributor and the slaves to the outputs of the distributor.
y In the user interfaces of the VENICE client software (already con-
nected to the channels) set one of them to act as the master and
configure the remaining ones as slaves via their VENICE configura-
tion settings (see section “Gang Settings” on page 4-3).
y Activate for all channels in the VENICE client software the slave
mode (for the master as well as the slaves).
y The multi-device operation can now be controlled via the slave
mode control window of the master channel.
With this the setup of the multi-device operation is complete. When
controlling the master channel via its slave mode control window (see
the “VENICE Client Software” user guide), the slave devices will follow
any operation initiated on the master, including e.g. slow/fast motion,
jog, shuttle, loop, and reverse play-out.
2.4.2 Synchronizing the Devices
In most multi-device applications, you will have to synchronize the con-
nected devices.
All connections have to be made with standard RS-422 cables.
To connect more than two video channels an RS-422 distribu-
tor has to be used.
