VOLUME
NAME
volume - Sets or gets the volume mute settings
SYNOPSIS
volume {get|up|down|set}
DESCRIPTION
The mute command is used to get or set the system value for either audio or video mute state.
OPTIONS
get- Returns the current volume value
up- Increases the audio volume by one
down- Decreases the audio volume by one
set -Sets the volume to the level. The volume must be in the range from 1-11 inclusive
EXAMPLES
volume get- Gets the current audio volume setting
volume set 5- Sets the volume level to five

New Features & Functions
Initial Production Release
Known Issues:
VU Meter Operation:
The front panel VU audio meter is not properly working on this release. Specifically,
the VU scale does not have adequate resolution to be useful as visual indication of audio signal.
Recommendation is to actively listen to USB Record channel to adjust audio level or use the Windows USB
Record channel meter for visual indication of audio level. This will be corrected on next release.
EDID Compliant Input Source (Mac-Mini):
The HDMI input does not support EDID forwarding at this time.
If an EDID compliant device such as the Mac-Mini is used as the source input, no video will be decoded. The
recommended work around is to use a third party EDID manager (i.e. Extron) if this is required in the
installation. EDID support will be considered in future release.
RGBHV Video Alignment-:
A slight video alignment issue may be apparent when various PC are the source
input to the RGBHV port. The issue is the RGBHV presentation can vary between different PC graphics
card. Recommend correction to any alignment issues is to adjust alignment on the PC display as needed.
Automatic alignment will be considered in future release.
Mute Indication:
The PC software may not properly display mute state of the AV Bridge when user initiates
mute from front panel button. This is due to limited support for mute notification from USB device to the Host
PC operating system. This applies to both Window and Mac OS. Mute activation from the Host PC will be
represented accurately on the AV Bridge.
Auto Detection of RGBHV & YPbPr Inputs:
The AV Bridge includes an auto detection scheme on the DB-
15 input that automatically synchronizes with either an RGBHV or YPbPr formatted source. However, the
detection scheme with 1280X720 can occasionally false between the two formats. A work around is to
specify the input source type ( RGBHV or YPbPr) in the A/V configuration web page or on the front panel.
Power Failure during Configuration Change:
A system lock up may occur if a power failure occurs when a
user is changing the Video or Audio Input sources within the software. This can cause a file corruption due to
power failure prior to the write cycle committing the changes. To recover from this lock up the user will need
to perform factory default operation.
