COMMUNICATION PORTS
Your Nº30.6 includes both RS-232 and the Mark Levinson Linking system
communications ports.
The RS-232 port may also be used to update the operating software of the
Nº30.6, so that your system will be able to handle new digital audio formats
as they are introduced. (Think of updating the software in the Nº30.6 as
being like installing new software in your computer… only much less pain-
ful.) Once again, your dealer can assist you in taking advantage of these
advanced features, should the need arise.
The “pinout” connections used on the RJ-11 connector used for the RS-232
port is as follows:

Note that only qualified technicians should attempt to make use of the spe-
cial capabilities afforded by this RS-232 communications port.
Linking connections
The Mark Levinson Linking system uses the Nº30.6 as the Master of (and
central clearinghouse for) inter-component communications. Other compo-
nents such as digital transports are connected to the Master as “Slaves,” and
can be “daisy-chained” using their Slave In and Slave Out jacks. As the ulti-
mate destination of all source signals, the Nº38 or Nº38S Preamplifier (if
owned)
must
be the final “Slave” in the chain. (
In technical terms, it termi-
nates the communications bus
.) In turn, the Nº38 can serve as a master to
an associated compatible Mark Levinson power amplifier—hence its “Mas-
ter” communications port.
Thus, if the only other Mark Levinson Link-compatible component you
have is the preamplifier, connect the Nº30.6’s
master
port to the
preamplifier’s
slave
port using a “straight-through” RJ-45 cable. If there are
additional Mark Levinson Link-compatible components in the system, place
the preamplifier at the end of the chain by connecting the last
slave out
port to the Nº38’s
slave
port. See the diagram at left for clarification.
The RJ-45 cable needed for the Link connection between the Nº30.6 and
other Link components may be purchased from your Mark Levinson dealer.
It may also be made to length using two RJ-45 connectors and the appro-
priate length (up to 100 feet/30 meters) of RJ-45 (flat, eight conductor)
cable.
