Notes
•
The I/O jacks are DT04-4/p and DT04-6/p
from brand TE Connectivity
•
If possible, some jacks will be combined/
eliminated; for example if power for M-Link
can be drawn from the CANBUS network
connection, the power connection to the M-
Link will be removed
•
This sketch is NOT meant to represent the
Industrial Design for the M-Link —that ID
will be integrated into the product design
during Beta development phase
•
Rather this sketch defines the overall mech
configuration and the minimum dimensions

hVOL bVTR

=
80% 50% 40%
hVOL is “Host Volume”; a GLOBAL
volume which is always maintained
and stored in the SKAA transmitter.
hVOL is usually linked to the host
device volume (e.g. iOS, Mac OS,
Windows or Android system volume)
and mirrors it. If volume data from
the host device is not available (for
example from dumb audio sources
like a 3.5mm AUX input), then hVOL
is set to full up.
hVOL affects all receivers bonded to
this transmitter (up to 4 of them)
bVTR is “Bay
Volume Trim”
This is a LOCAL
volume which
is stored and
maintained in
the Receiver.
If this Receiver
is part of a
Cluster, bVTR
affects all
nodes in the
Cluster.
nVOL is transformed
through a volume table
(so a log curve may be
applied) prior to
sending the volume
commands to the
amplifier chip via I2C

bMUT is “Local”

nVOL is

nVTR

nVTR is “Node
Volume Trim”
which is
disabled (set to
full up) in most
products.
It is used only
in select cases,
such as for
trimming
volume in
subwoofers
which are slave
nodes in
Clusters.
If this Receiver
is part of a
Cluster, only
this receiver is
affected (all
other member
nodes of the
Cluster are not)

•
M-Link Global Volume (SKAA API hVOL) is
always fixed at “full up” (0xFF)
•
M-Link I2C volume scaling takes place in
the DAC chip

Rx mode
60 min after
entering
Standby
Sleep
Notes
•
“VO” means Virtual Off —this is a power saving
state for SKAA transmitters, triggered by lack
of audio (silence).
•
In VO state, Ginseng’s RF section is shut off
causing all Bonds to drop (all Bonded SKAA
receivers are dropped)
•
“Standby” is a power saving state for SKAA
receivers.
•
in Standby state, Ginseng shuts off the ADC,
DAC and buffers
•
“Sleep” is a power saving state for SKAA
receivers. Sleep is triggered by a loss of Bond.
•
In Sleep state, the SKAA receiver improves on
the power saving performance of Standby state
by also duty cycling the SKAA radio. You can
tell the unit has gone to sleep when the SKAA
indicator shuts off and the Power LED dims
•
Powering off certain chips will be effected by
holding them in RESET
•
Power OFF commands sent from MFD to M-Link
will actually place the M-Link into VO or Sleep
state
