Establishing The Data Connection; Calling Memorized Adjustments; Modifying The Adjustment - IMG STAGELINE L-RAY/1000 Mode D'emploi

6.3 Establishing the data connection

6.3.1 Control of several systems via
the RS-485 data bus
For controlling several L-RAY systems via the
RS-485 data bus, each system must first be pro-
vided with a name and an individual ID number.
This is only necessary for the first operation. The
systems memorize these data and can thus be
addressed separately. If the designation has
already been made, the connection set-up can
be started with step 9).
1) Separate all data connections between the
systems.
2) Connect the first system via RS-485, RS-232,
or USB to the PC. Start the program "Active
Speaker Controller".
3) Call the menu item "Communications ± Enable
Communications". The program looks for a
connected L-RAY system and shows the sys-
tem found in the list under "Select Device:"
and the current number and the current name
of this system under "Current Device Infor-
mation".
4) Start the connection set-up with clicking
"Connect". (At this moment it is of no impor-
tance which option has been selected under
"Data Configuration".)
5) After the connection has been established
and the data have been read by the system
("-> Program Data Transferred
appears in the status line below), call the
menu item "Device ± Edit Current Device
Information".
The window "Edit current device informa-
tion" with the current ID number and the cur-
rent name of the connected system is shown.
6) Enter a unique ID number (1 – 10) and a sig-
nificant name (a maximum of 14 characters
of the ASCII set of characters) for the system
into the corresponding field and confirm with
"OK". The data are transferred to the system
and shown as "Current Device ID" and "Cur-
rent Device Name" in the main window on the
top right.
7) Separate the connection via the menu item
"Communications ± Disable Communications".
"-> Disconnected" appears in the status line.
8) Remove the connection cable from the con-
nected system and connect it to the next sys-
tem.
Repeat steps 3) to 8) until all systems are clearly
named. Then connect the systems with each
other again and the first system to the PC.
9) Call the menu item "Communications ± Enable
Communications". Now all systems connected
appear in the list under "Select Device:".
Select the system to be configured and then
the direction of the data transfer "Data Con-
figuration":
"Upload Program Data from Device": The
current data from the L-RAY system (start
setting) are transferred to the PC. This option
is preset and should also be used for the first
operation.
"Download Program Data to Device": The
settings on the PC are transferred to the
L-RAY system. This option is useful if data
have already been loaded from a file or
another L-RAY system.
Start the connection set-up by clicking
"Connect". With the key "Esc" or by closing
the dialogue window the process can be
stopped without connection set-up.
6.3.2 Control of individual systems
For connecting only a single system to the PC at
a time, even if several systems are used:
1) Connect this system via RS-485, RS-232, or
USB to the PC. Start the program "Active
Speaker Controller".
2) Call the menu item "Communications ± Enable
Communications". The program looks for a
connected L-RAY system and shows the sys-
tem found in the list under "Select Device:"
and the current number and the current name
of this system under "Current Device Infor-
mation".
The differentiation of several systems by
means of the number registered here is of no
importance to the data transfer as long as the
units are not to be connected via a common
data bus.
3) Select the direction of the data transfer "Data
Configuration":
"Upload Program Data from Device": The
current data from the L-RAY system (start
setting) are transferred to the PC. This option
is preset and should also be used for the first
operation.
"Download Program Data to Device": The
settings on the PC are transferred to the
L-RAY system. This option is useful if data
have already been loaded from a file or
another L-RAY system.
Start the connection set-up by clicking
OK..."
"Connect". With the key "Esc" or by closing
the dialogue window the process can be
stopped without connection set-up.
To separate the connection later, call the menu
item "Communications ± Disable Communica-
tions".
Note: In exceptional cases, the installed program may
be aborted after its start. This may happen when anoth -
er device has been assigned to the serial COM port 3.
For data communication, the program "Active Speaker
Controller" expects COM port 3 to be free. To make
COM port 3 available, it is recommended to assign the
other device to a different COM port, if possible [e. g.
under: Control Panel /Administrative Tools / Computer
Management / Device Manager / Ports (COM and LPT)].

6.4 Calling memorized adjustments

In the EEPROM of the signal processor six dif-
ferent adjustments "Program" can be memorized
which are maintained even after disconnecting
the power supply.
To call an adjustment memorized before in the
EEPROM of the signal processor:
1) Call the menu item "Program ± List Program
& Recall". The window "List Program" opens
and shows the list with the six adjustments
memo rized in the EEPROM of the signal
processor.
2) Click the button "Recall" next to the desired
program. The signal processor switches to
the selected program and the data of the
adjustment are transferred to the PC and are
displayed.
If none of the programs shown is to be
called, close the window with the mouse or
press the key "Esc".
The memorized adjustment "Current Program"
last called is automatically active when switching
on the L-RAY system (start setting).

6.5 Modifying the adjustment

Attention!
In connection with the control programme the
signal processor is an effective tool which allows
to make very fine but also substantial modifica-
tions of the characteristics of the speaker system.
Any modification of the parameters should
therefore be made with caution and special
knowledge. Extreme modifications of the
adjustments may at the worst damage the
speaker system.
When the PC and the L-RAY system are con-
nected, modifications of parameters on the PC
are immedi ately transferred to the L-RAY sys-
tem. However, they are only memorized in the
RAM of the signal processor and are not kept
after switching off the L-RAY system. To keep
the adjustments permanently, they must be
memorized in the EEPROM of the signal proces-
sor ( chapter 6.6).
In the main window of the program, the sig-
nal way through the amplifier system is shown as
a block diagram ( fig. 7). From the input on the
left side the signal passes through the blocks
PEQ and LEVEL first and is then split to the two
output branch es LOW and HIGH. The LOW sig-
nal is fed to the amplifier of the bass speakers,
the HIGH signal to the amplifier for the mid-high
range speaker units. When clicking the function
blocks, the window below the block diagram
shows the corresponding adjustments. The
adjusting possibilities of the different function
blocks are explained in the following:
PEQ
In these function blocks, 6 or 2 (at the input)
independent filters to be combined are available.
By clicking the number of the filter select the
filter to be configured. The selected number is
shown in red.
The type of the filter can be selected from the list
under "Type:":
None
The filter is deactivated
Peaking
The filter curve has the shape of a bell, the
fol lowing parameters can be adjusted
Frequency = centre frequency
Q-factor (bandwidth)
Level = boosting or attenuation of level
Bandpass
Band-pass filter with level attenuation above
and below the centre frequency, the following
pa rameters can be adjusted
Frequency = centre frequency
Q-factor (bandwidth)
Hi-Shelf
Boosting or attenuation of all frequencies
above the limit frequency, the following
parameters can be adjusted
Frequency = limit frequency
Level = boosting or attenuation of level
Lo-Shelf
Boosting or attenuation of all frequencies
below the limit frequency, the following
parameters can be adjusted
Frequency = limit frequency
Level = boosting or attenuation of level
Notch
Maximum attenuation of a selected fre-
quency, the following parameters can be
adjusted
Frequency = centre frequency
Q-factor (bandwidth)
The adjustment of the selected filter and the
curve resulting from all filter adjustments are
shown in the frequency diagram.
