Special Features Of The Smartview Xpro; Synchronising Smartview Xpros For Multiple Video Head Applications - ADDER 2XPRO Installation & Use Manual

5. Special features of the SmartView XPro

The following special features of the SmartView XPro are implemented by firmware
versions 1.12 and above. If you have an earlier version of firmware loaded into your
SmartView you will need to download the latest firmware release from the Adder
website (www.adder.com) and upgrade your SmartView before you can make use of
these features (see section 6 for upgrade instructions).
5.1 Synchronising SmartView XPros for multiple video head
applications (requires firmware v1.12 or above)
Multiple SmartViews may be connected together so that they operate in a
synchronised manner. Synchronised operation is useful for applications that require
multiple video signals to be switched together. This type of operation is usually
required where each computer is fitted with multiple video cards or video cards with
multiple video heads. Such configurations are typically required in banking and
engineering applications where greater video 'real estate' is required. Whenever the
SmartView's channel is switched it sends an RS232 command out on its serial
interface. The SmartView switches its channel if it receives the same command on
its serial interface. Consequently, by linking the serial interfaces a master unit may
be made to automatically switch a daisy chain of slaved units as shown in the
diagram below.
It should be noted that the synchronisation cable deliberately does not have the
transmit pin of the Slave End connector linked to the receive pin of the Master End
connector. To do so would cause the Slave unit to be able to switch the Master unit.
This would setup an endless cyclical switching sequence that would prevent the
SmartViews from operating correctly.
