Lightware’s frame detector function works like a signal analyzer and makes possible to
determine the exact video format that is present on the port, thus helps to identify many
problems. E.g. actual timing parameters may differ from the expected and this may cause
some displays to drop the picture.
Frame detector measures detailed timings on the video signals just like a built-in
oscilloscope, but it is much more easy to use. Actual display area shows the active video
size (light gray). Dark gray area of the full frame is the blanking interval which can contain
the info frames and embedded audio data for HDMI signals. Shown values are measured
actually on the signal and not retrieved only from the HDMI info frames.
6.4.6. Analog audio properties
Certain parameters of analog audio input
signal can be adjusted as follows:
▪
Volume
: from 0 dB to -52 dB (step
0.25 dB), from -54 dB to -66 dB
(step 2 dB); -69 dB; -72 dB; -78 dB
(default is 0 dB).
▪
Balance
: from 0 to 100, step 1 (default
is 50 = center).
▪
Gain
: 0 dB / 3 dB / 6 dB
6.4.7. Test pattern generator (no sync screen)
The output ports can send a special image towards the sink devices for testing purposes.
The setting is available on output ports with the following parameters:
Mode
▪
On
: the test pattern is always sent to the output port.
▪
Off
: the test pattern generator is off.
▪
No signal
: the test pattern generator is switched on if no video signal is switched to
the given output port.
Clock source
▪ 480p / 576p / Original video signal: the clock frequency of the test pattern.
Pattern
▪ Red / Green / Blue / Black / White / Ramp / Chess / Bar / Cycle. Cycle setting means
all the patterns are changed sequentially approx. in every 2 seconds.
ATTENTION!
The Mode can be set individually on each port, but the Clock source and the Pattern are
common for the output ports. E.g. the Clock source and Pattern settings are the same on
LINKOUT (O1) and LOCALOUT (O2) output ports.
6.4.8. Laser enable setting
Two modes can be set on fiber
optical interface.
Mode
▪
On
: high-speed (AV signal) and low-speed (serial) communications are transmitted.
▪
Standby
: only low-speed communication is transmitted.
