Page 5: Overview
RCU, either at the main system or in the remote room, is the responsibility of the third party controlling device. Other RCU controlled rooms in the Knekt system are unaffected, and operate both Linn and non-Linn sources in the normal way. A4 A3... -
Page 6: Installation
(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. -
Page 7: Av5103 / Kairn "Hybrid" Parallel Main System
AV5103 / Kairn which are not part of the main system i.e. they do not need an associated Intersekt source. Local Linn sources (one cd and one tuner) should be connected into the AV5103 / Kairn remote in/out loop. -
Page 8: Av5103 Remote Room
REMOTE OUT/IN of the line receiver, with its audio going to an AAI of the AV5103. If no local Linn source is used, the REMOTE IN of the line receiver must be looped to its REMOTE OUT via a single phono lead. -
Page 9: System Operation
RS232 port on the Intersekt using its ASCII command language. OMMAND YNTAX The Intersekt provides a simple text-based (ASCII) command set to control and monitor the Linn equipment normally controlled by an RCU. All commands have the following generic format. Command string Parameter string... -
Page 10: Enabling Ascii Command Mode
QUIPMENT To minimises both the RS232 communications between the Intersekt and the controlling device, and the communications between the Intersekt and the Linn equipment being controlled, a two stage monitoring system has been implemented. The current “amplifier” or “source” device status is read into data buffers within the Intersekt when the system commands [rSTAT=AMP] or [rSTAT=SRC] are received, or when a command which automatically reads the current device status is received. -
Page 11: Command -Response Timing
RS232 Knekt Interface CD player has been selected as the “source” device for room eight, sending the command [?8MODE] would return the list of MODE command/parameter combinations available. OMMAND ESPONSE IMING The time interval between receiving a command and the response being returned is dependant on both the type of command, and on the individual equipment the command is destined for. -
