10. DN9340E AND DN9344E REMOTE CONTROL SETUP
A slave network of up to 32 DN9340E/DN9344E units can be linked together and remotely controlled
from a PC running the Elgar Library Manager and HELIX DN9340E or DN9344E RCS add-in software.
Further details on these commercially available software applications can be found on the Klark
Teknik website at www.klarkteknik.com.
10.1. Overview
To control an equaliser network, the laptop/PC running HELIX RCS is connected to the network in
place of a Master DN9340E HELIX, assuming control of the daisy-chained HELIX units under pre-set
slave addresses. The following options for connecting the laptop/PC to the HELIX unit(s) are
available:
Ethernet: Covers direct Ethernet, Local Area Network (LAN) or wireless connection,
converting to an RS-232 front panel input via a Lantronix UDS 100 Converter.
Wireless offers increased flexibility during the event set-up, as the engineer can
move around freely with a laptop and adjust the equalisation while listening to the
end effect at any place in the venue.
Serial (option): The optional RS-232 serial connection is via the “PC PORT” on the front panel of
the first HELIX unit. It is possible to connect other HELIX DN9340E/DN9344E units
via the rear Ethernet port(s) when using a serial connection, but note that this will
be slower that using Ethernet.
The following sections describe how to connect the master HELIX RCS laptop/PC to the system for
each option, and the interconnectivity of the HELIX DN9340E/DN9344E units.
Note
If Solo Tracking input is required, the first slave HELIX must be a DN9340 and the front panel
RS-232 PC Port must be used, see Page 44.
10.2. HELIX DN9340E/DN9344E unit interconnections
The HELIX DN9340E/DN9344E units in your system can be connected together in a daisy chain, or
each one can be connected to an Ethernet switch or hub.
Note When connecting the Ethernet cable to the rear panel of a HELIX DN9340E or DN9344E unit,
either of the Ethernet sockets can be used.
