Understanding the SLAVE Mode
The SLAVE mode is only used for the multi-channel video switcher
configuration
1
, for example, when using 3
VS-1616V
units to form a YUV
switcher, as Figure 7 illustrates.
One unit is used as the Master, and the other 2 units are Slaves. The Slaves
always follow the Master. In the example illustrated in Figure 7, the first
VS-1616V
unit is the Master (with DIP 6 set OFF disabling the Slave mode)
and the second and third
VS-1616V
units are Slaves (with DIP 6 set ON
enabling the Slave mode).
On both Slave
VS-1616V
units, the MATRIX and STATUS Displays do not
illuminate and the STATUS Display shows the following message:
Keyboard LOCKED
However, the STATUS Display on each Slave
VS-1616V
unit dynamically
shows
2
all changes made from the Master
VS-1616V
unit.
Front panel control is via the Master
VS-1616V
unit, on which the front panel
buttons are unlocked and both the MATRIX and STATUS Displays
illuminate.
6.6 Connecting a Control Interface
Connect a control interface (RS-232 or RS-485) unless operating a
VS-1616V
as a stand alone unit without any control device (that is, with control from the
front panel or IR port, and not via a remote controller or a PC).
The control interface must be identical on each switcher in the series of 16x16
matrix switchers; either RS-232 or RS-485. One control interface suffices. Do
not use both RS-232 and RS-485 control interfaces in the same configuration.
For example, in an interconnected varied-format 16x16 switcher application
3
,
if the switcher that connects to the PC connects via the RS-232 control
interface, each switcher must interconnect via the RS-232 control interface
and not via the RS-485 control interface.
Choose the RS-232 control interface, for a range of about 25 meters used for
a point-to-point connection.
