Modifiable Description
Aux. Card ID
NO
Hardware ID of Auxiliary Card.
Aux. Card FPGA Rev.
NO
FPGA Rev. of Auxiliary Card.
Original KMASS
YES
Option to use previous Interface revisions.
Allow Out Of Band
YES
Allows On-screen Display when used with Routers.*
Alt. HOT Key
YES
Used to modify Out Of Band Hot Key.
*Contact Thinklogical before using this feature as it may impact the fiber channel.
*DDC
DDC PROM Emula. Mode
YES
Options are Dynamic, Static and Passthru.
In
Dynamic mode
, the EDID table* of the monitor connected to the
RX is read and stored on the TX. After any change in monitor type
a new EDID table will be stored on the TX. An EDID table is always
presented to the video source, whether the TX is ON or OFF.
Static mode
is used to maintain the current EDID table regardless
of monitor changes at the RX. An EDID table is always presented to
the video source, whether the TX is ON or OFF.
Passthru mode
makes the DDC pins look like direct connection
between the TX and RX, allowing the computer to talk directly to
the monitor.
Load Default DDC
YES
Loads the default EDID table* into the TX which allows 1024x768
and 1920x1200. This puts the TX into static mode.
Load 1080p
YES
Loads a widescreen version of the EDID table* into the TX.
Supported resolutions include 1920x1080 and 1280x720.
Acquire DDC
YES
Gets the EDID table* of the attached display, stores the information
on the TX, and puts the TX in static mode.
Force DDC Mode
YES
Used to force a monitor to appear as either
digital
or
analog
.
Since the Velocity products can convert between analog and
digital, sometimes the EDID table* must be modified to match the
method of connecting the TX to CPU.
*Video
VGA Connected
NO
An indication of whether VGA video is input to the Vis TX.
Resolution
NO
Active pixels x active lines vertical rate.
Hor. Freq
NO
Horizontal frequency.
Auto Phase
YES Automatically adjust the Sampling Phase to the best setting.
PLL Total
YES Total pixels, one line. (Horiz. active Horiz. blanking pixels).
HSOut Width
YES Horizontal sync (Hsync) of video, measured in pixels.
DE Start
YES
Horizontal back porch (Hpb) of video, measured in pixels.
DE Width
YES
Total active pixels in one line.
Line Start
YES Vert. back porch (Vbp) + Vert. sync (Vsync) measured in lines.
Line Width
YES
The number of visible lines.
Hsync Period
NO Used to determine analog video horizontal frequency.
Use the following formula to calculate the frequency:
(25x10E6 x 16) / Hsync Period = Horizontal Frequency
Vsync Period
NO
Total lines in one video frame = active lines + blanking lines
ISL Sync Status
NO
Thinklogical support use only.
Measures sync selection & polarity.
ISL Sync Activity
NO
Thinklogical support use only.
Measures sync activity.
Video RX 1 cnt.
NO
Thinklogical support use only.
Video IN 1 clock (in hex).
