"Note: In smaller systems it is not unusual for your VLPro Sever and Client to be
on the same computer.
Your initial setup is now complete. All other configuration can be performed through the VLPro Client.
3. CONNECTING TO VLPRO
Open VLPro and click on the refresh tree icon. Expand the hardware tree by clicking on the “+”. Your
7780R2x1-CS-2 should appear as a newly listed device with the IP address used earlier to configure
the card. It may take a few minutes to appear while the card and switch negotiate network settings (this
can be verified directly on the switch if necessary).
"
Note: If after a couple of minutes the card has still not appeared try selecting
Add Agent from the Tree> Add/Update Agent menu. Enter the IP address used
in the configuration stage earlier and select OK. The card should now be listed
and will remain greyed out for a moment while VLPro finds the card and
confirms its configuration.
Please consult your network administrator if you continue to have problems connecting the card with
VLPro, alternatively contact Evertz Microsystems Ltd. or your authorized reseller for technical support.
4. 7780R2X1-CS-2 OVERVIEW
The 7780R2x1-CS-2 provides a means of switching between two identical ASI streams without any
visual or audible interruptions to any of the channels in the stream. The part number 77880R2X1-CS-2
refers to the dual switch version that provides two fully independent clean switches in one two-slot
board for a standard 7700 3RU chassis.
The board can operate in two different modes, Packet-matching or GOP boundary switching. The
packet-matching mode makes a clean switch by buffering and finding the same reference point in both
streams. When a switch is initiated the stream input is seamlessly swapped. Downstream devices will
not be able to detect this change and no interruption will occur on professional or consumer set top
boxes. This mode is ideal for identical inputs from the same route source (the same mux).
In GOP mode, the switch will wait for the end of the group of pictures and generate a switch on the next
I frame to reduce the visual artefacts. Often the switch is very clean. Downstream devices will not
display an outage that is often expected from ASI switches. However, some visual artefacting may be
present. This mode is ideal for non-identical streams (exactly the same content from different muxes).
Clean switching is still possible between the two streams even if one of them is delayed (maximum 3
seconds per switch). While it is possible to make manual (clean) switches for engineering works, the
switch can be fully configured to respond to TR101 290 test conditions and each is fully independently
custom configurable. This capability provides a rapid response clean switch to signals that may be
beginning to break up or have begun to exceed the specified limitations of the tests.
