The Performance section of the screen gives an indication of the quality of the video.
Changes/frame is the average number of tiles that change for each frame sampled by
the hardware. Flatness is an indication of what percentage of the screen contains tiles
that are comprised of only one color.
The Regrab Screen button in the Actions section causes the screen to be re-captured.
When making small changes to the video parameters, sometimes these changes are
not reected in the displayed screen immediately, particularly if the noise lter is
enabled. Press this button to see the immediate eect of the changes.
Use the Show Dis button to learn which parts of the screen are being sent over the
Internet. When you click this button, the screen is cleared to a medium grey color. All
blocks that are sent from that point on will show up on the screen as they are sent.
Click the button again to reset the screen to grey. To return to normal operation, click
the Regrab button. It is very easy to visually identify the eect noise has on signal
processing, using this feature.
The Auto Oset & Gain button in the Actions section invokes the automatic algorithm
for setting the video parameters. The algorithm requires the factory calibration test
pattern to be correctly displayed on the screen.
Using the Modem Feature
The Modem feature allows the CABCONS1716I to act as an Internet connection server
for increased security and exibility in connecting with the host computer.
Unlike the TCP/IP connection used with the standard Web conguration and VNC
clients, the modem creates a one-to-one connection between the CABCONS1716I and
the computer you are using, bypassing the public Internet completely.
NOTE: This feature requires both an external modem (most standard connection
protocols are supported) and a dedicated phone line that can be connected to the
modem for external access. While it is possible to use the modem feature through
some PBX systems, this increases the complexity and reduces the performance of
the connection. For clarity, the instructions presented here assume that the modem
is connected to a typical POTS (Plain Old Telephone System) line that is not routed
through a phone management system or shared with other devices.
If you wish to use this feature through a PBX system, it may require some
experimentation and additional support from your telecom services provider, and is
not supported by StarTech.com.
