9.DN9848 REMOTE CONTROL SETUP

Up to 32 DN9848 Loudspeaker processors can be linked together in a daisy-chain RS-485 network for remote control from a computer running the commercially available Stardraw or Smaart software. Further details of these applications are available from the Klark Teknik website at

www.klarkteknik.com.

This section specifically covers how to connect and configure the DN9848 units for remote operation. For operational guidance on using the Stardraw or Smaart remote control applications with the DN9848, please refer to the manufacturer’s documentation.

To set up a slave network of DN9848 units for remote control from a PC,

1Using standard balanced mic cables, connect the DN9848 units together in a daisy chain sequence from the rear panel RS-485 COMMS In connector on one unit to the COMMS Out on the next. The first unit in the chain will have no connection to its input, and the last unit will have no connection to its output. Note that when using an RS-232 connection to the PC, up to 32 units can be included in the daisy chain, but when using an RS-485 connection to the PC, the maximum is 31 units.

2Power up and put each unit in remote control mode by assigning it a unique Comms channel address as follows:

Press and hold the HOME (SETUP) button to access the Comms menu page.

Use the left-hand knob to select a channel between 1 and 32.

Press HOME (SETUP) to accept.

The front panel controls, except the HOME (SETUP) button, are locked out to facilitate remote operation. The display indicates that the unit is under remote control.

Note

The order of the addresses does not need to mirror the order of the daisy chain networking, but each unit MUST have a unique comms channel address.

3Referring to the table overleaf, connect your laptop/PC to the DN9848 daisy chain as relevant to your specific system set up. Note that, as the RS-485 network has through connections, you may connect the PC to any unit in the chain.
