RS232 Knekt Interface
5
INSTALLATION
The diagram shows the wiring of a typical system configuration. The Intersekt is connected to other
Linn equipment using 8 way cable terminated with RJ45 plugs. The RS232 port of the of the third
party controlling device is connected to the PC port of the Intersekt using an 4 way cable terminated
with a RJ11 plug (Linn part CONN229 - 9 way ‘D’ type socket to RJ11).
RCU
CONTROLLED ROOMS
The RCU controlled rooms are connected as normal, and installed via the Linn installation utility as
if they were the only rooms in the system.
RS232
CONTROLLED ROOMS
Line receiver / Majik remote room
The cable from the ROOM port of the Intersekt is connected to the dA port of the cable adapter
(Linn part PCAS187) in the remote room. The adapter routes the audio signals from its MAIN port
to the Balanced Audio input of the Line receiver / Majik, and the bi-directional control signals from
its REM port to the RCU port. If local Linn sources are used in the remote room, they are connected
as normal.
AV5103 / Kairn Parallel main system
The cable from the RCU port, or the ROOM 1 port, of the Intersekt is connected to the MAIN port
of the cable adapter to terminate the bi-directional control signals. The remote in/out of the parallel
AV5103 / Kairn is connected to the remote out/in of source 1 on the Intersekt. The audio from the
main system sources is connected to the appropriate Intersekt and AV5103 / Kairn audio inputs, as
required. Note that the mapping between an Intersekt source and the associated AV5103 / Kairn
source is selectable, and does not need to be “one to one”. It is also possible to connect local sources
