Remote Control - Klark Teknik HELIX SYSTEM DN9344 Operator's Manual

Remote Control:

Connections
A DN9340 master unit can control both DN9340 and DN9344 units as slaves. In order to set up a remote
controlled Helix system, first connect the units together using the RS-485 connectors on the rear panel. The
units are connected in sequence from output to input, in any order. The first unit in the chain will have no
connection to its input, and the last unit will have no connection to its output.
Addresses
The RS-485 network uses a system of addresses to identify which unit is being controlled. The Helix system
supports addresses from 1 to 32. A DN9340 unit has one address and a DN9344 has two addresses,
corresponding to the left-hand pair of channels (Section 1) and the right-hand pair of channels (Section 2)
respectively. The reason for having two addresses to communicate with each DN9344 is to allow systems to
be built up from either DN9340 (2 audio channels) or DN9344 (4 audio channels) in any combination. At any
time, two DN9340s can be replaced by a single DN9344 (or vice versa) without any need to change the
addressing of the system.
Data model
Each Helix unit has a "

memories in each DN9340 and in each pair of channels in a DN9344.

When using remote control, the Master unit holds a local copy of the working memory for
connected. This allows fast switching between units being controlled. When the system is set on-line, the
user can choose whether to "Get all" data from the slaves or to "Set all" data from the master. This allows the
settings for up to 64 channels of audio to be stored in a single DN9340, or conversely an "empty" master
DN9340 can be connected to a system that is already running and upload the system data.
Getting started
Connect the units using the RS-485 ports as described above. Set the comms address for each slave unit -
ignore the master unit for now. It doesn't matter what addresses you use, but each unit MUST have a unique
address (two unique addresses for a DN9344).
On a DN9340:
