Section 2: Installation- Connections
DATAPORT Connection- This section applies to those users interfacing
with the QSC DataPort products. If using the DataPort for your audio inputs,
DO NOT use the terminal block inputs. If the DataPort is used only for
control & monitoring of the amplifier (no audio input through the DataPort),
then audio input may be via the terminal-block connectors.
RS-232 PORT Connection- Connection to the RS-232 port is made
using a 9-pin serial data cable (male-to-female). Cable length should be 25
feet or less. Orient the DB-9 plug correctly, insert the plug fully into the RS-
232 port and finger-tighten the retaining screws.
DSP-3 setup and programming takes place through the RS-232 port. Any
time setup changes are required to the DSP-3, it must be connected to its
host computer through the RS-232 port. If “real-time” control of the DSP-
3 is required, the RS-232 port connection must be maintained as well. If
“real-time” control is not required, then the DSP-3 can be setup first and
then disconnected from the PC.
The RS-232 connection does not have to be maintained for the
DSP-3 to operate.
Setup & programming can also be done via Ethernet network
communication when using QSC’s QSControl products. Refer to
QSControl documentation for detailed information.
DataPort Connection: 15-pin Cable
RS-232 Connection: 9-pin Cable
The front-panel DataPort connection is used for connecting to
QSC DataPort products. Use a
QSC DataPort cable (male-to-
male)
similar to VGA computer monitor cables.
Do not use com-
puter VGA cables as they are not correctly constructed for
use with the DSP-3.
QSC DataPort cables may be obtained
through your QSC distributor or by calling QSC’s Technical Services
Department. The plugs and jacks are the same physical size as the
RS-232 connections; be careful not to get them confused.
The rear-panel DataPort connection from the DSP-3 to QSC
amplifiers is made when mounting the DSP-3 to the rear of the
amplifier. The DataPort connection from any other accessory to the
DSP-3 is made by orienting the connector properly, inserting it fully
into the jack and finger-tightening the retaining screws. The audio
signals on the rear-panel DataPort are post-DSP (processed).
Front panel DataPort connection is
not required
for the operation
of the DSP-3.
