COMPUTER PARALLEL PORT: connector for link to PC parallel port with supplied cable. It is used with ET

Commander software. See “Control protocol” to use a customised software.

TURNTABLE (REVERSE SLAVE): connector for second turntable, which must be always used contemporary with

Master turntable (connector on rear panel). Slave turntable spin always in
opposite sense respect master turntable and is passive (don't is possible
control directly slave turntable without master turntable).

RESET: push-button to restore zero degrees position (measurement starting position).

It can be used to avoid cables twisting as well.

ZERO: when LED is lighting the turntable is at zero degrees position (0°).

AUTO: twin LED indicator turntable rotation direction both in automatic or manual

mode.

DEG STEP: angular increments control switch (min 5 deg - max 45 deg). Used only in

automatic control from PC measurement cards. (COMPUTER connector on
rear panel).

MANUAL: manual rotation direction control. Pushing the manual buttons the turntable will

move only in a linear mode. Therefore will not step by a fixed number of
degrees, so you must see the turntable and release the buttons at desired
degrees rotation.

TTL OUTPUT DELAY ADJ: screwdriver adjustment for TTL pulse output delay using MLSSA

measurement system only. This delay adjustment, from 3 to 25 seconds,
occur between two measurement taken from MLSSA to achieve the desired
time measurement condition.(i.e. you can adjust the delay to obtain rotational
speed of 1 sec. 1 degree - Heyser).

Software applications

- ET Commander –

is a program that allow to control by PC one or maximum two ET1.1-ST2 Outline turntables.

Main features:

 Movement in both sense rotation to desired position degrees.
 360° automatic spin with settable degrees step
 Macro store of same positions
 Start command for 360° automatic spin and macro operations, in 4 mode:

a) Manual: by a key pressure.
b) Timer: automatic with timer.
c) External: by an external TTL pulse on parallel port.

d) Internal: the program wait a bit changing reading an internal address of parallel port (for expert programmer

only).
With two turntables:
 It is possible to make 360° automatic spin for both turntables in alternate or sequential mode.

- LMS Applications -

for LMS use are included four predefined macro programs to easy change type of

measurement and angular increment, even if everyone will write his own macro program.

1. SPL Normal Fixed Frequency: the macro that perform this measurement is POLFIX.MAC (LMS 3.05) or

POLFIX35.MAC (LMS 3.5) which use POL***.SET to define measurement parameters and POLFIX.LIB to
handle and store the data.
A special Menu allows the user to select test frequency of 18 1/3 octave spaced.
POLFIX.MAC (POLFIX35.MAC) makes 24 measurements with different angular positions; set the selector
switch (DEG STEP) to 15 degrees step.

Example:

Operation : The macro program menu is selected by pressing the (M) key at the main menu. The work area
contains a window listing *.MAC macro files. The cursor keys are used to scroll thought the macro file listing to
position the desired file in the highlight for an operation.
(L)oad/Execute command loads and then execute (runs) the selected macro file program. After pressing the (L)
key, the macro program will be loaded in to memory and immediately executed. From this time on, the LMS system
will be under program control until the program has finished.

2. SPL Gated Fixed Frequency: the macro that perform this measurement is POLFIXG.MAC (LMS 3.05) or

POLFIG35.MAC (LMS 3.5) which use POL***G.SET to define measurement parameters and POLFIXG.LIB to
handle and store the data.
A special Menu allows the user to select test frequency of 18 1/3 octave spaced.
POLFIXG.MAC (POLFIG35.MAC) makes 24 measurements with different angular positions; set the selector
switch (DEG STEP) to 15 degree step.

3.(4) SPL Normal (Gated) Frequency Sweep: the macro that perform this measurement is POLSWEEP.MAC (LMS

3.05) or POLSWE35.MAC (LMS 3.5) which use SPLPOL.SET(Normal) and SPLPOLG.SET(Gated) to define
measurement parameters.
POLSWEEP.MAC (POLSWE35.MAC) also use POLSWEEP.LIB to handle and store the data.
A special Menu allows the user to select Normal (sinewave) or Gated measurements.
POLSWEEP.MAC (POLSWE35.MAC) makes 12 measurements with frequency sweep from 20Hz to 20KHz and
different angular positions; set the selector switch (DEG STEP) to 30 degrees step.

Stored data will be handle according standard LMS practice.

NOTE: default frequency band is from 20Hz to 20KHz. To change permanently to a new range use the command

(F)requency Range for Sweep in (S)ystem menu and (S)ave as SPLPOLG.SET and SPLPOL.SET by Quick
Setup of LMS.

- For LMS 3.05 Users only ­To obtain the right synchronization with ST2/ET1.1 turntable you must change the LMS System Control Parameters
(SCP in the main menu) mentioned below.

Measurement type SCP15 SCP19 SCP20 SCP41

Standard Yes - 100 400
SPL Nor Fix No Beep 2000 20000
SPL Gat Fix No Beep 2000 20000
SPL Nor Sweep - - 2000 400
SPL Gat Sweep - - 2000 400

SCP41 in fixed frequency measurements must be >= 20000 to add 2 sec to the settling delay time between reads
and enable the right turntable rotation.
SCP20 define the trigger pulse width and must be = 2000 (20 msec) to assure the compatibility of control unit
ET1.1 both with LMS and MLSSA programs, without different dedicated electronics circuits.
Even if is not necessary to change the values of SCP15 and SCP19 it is recommended to speed up the
measurement.

These arrangements must be executed before macro loading, however they are remarked at the macro beginning.

SCP operations are not necessary for LMS Release 3.5 Users.

NOTE: actual Osc Level is setted on -20 dBm. You can change the default value according your
measurement necessity.

- MLSSA Applications -

for MLSSA use are included four predefined macro programs to easy change angular
increments measurement.
Of course you can edit every macro as you need

1. MLSSA POLAR5 ( 37 measurement cycles - 180 degrees).

2. MLSSA POLAR10 ( 19 measurement cycles - 180 degrees).

3. MLSSA POLAR15 ( 13 measurement cycles - 180 degrees).

4. MLSSA POLAR30 ( 12 measurement cycles - 360 degrees).

The macro POLMAIN will be helpful in starting operations, because it adjust some program setup automatically
avoiding troublesome inadvertence.

Example.

(M)acro (L)oad
message: MACRO LOAD FILENAME
operation: type POLMAIN (or Right Arrow) <enter>

(M)acro (E)xecute
message: MACRO LOAD FILENAME
operation: type POLAR5 (or Right Arrow) <enter>
message: TRANSFER AUTONAME ROOT
operation: type the measurement identification filename (max 5 char) then press <enter>.

Pressing <enter> without any specification the last is valid (or ROOT for the first measurement).

message: Position speaker on axis (0 degree position)
operation: position speaker on axis (0 degrees) in according with turntable OUTLINE ST2 0 position (press RESET

on ET1.1 if it is not or if you need to rotate counter clockwise the turntable ) set angular increment control
switch DEG STEP on 5 degrees and press <enter>.

From this time on, the MLSSA system will be under program control until the program has finished.

The same for POLAR10, POLAR15, POLAR30.

Before starting with measurement you must set angular increment control switch DEG STEP to the same value of
macro polar measurements.

MLSSA display each measurement superimposed one upon another in frequency domain as three-dimensional
plots (Waterfall Plots). "Smoothed" mode with 1/3 octave resolution allow you an easy read-out.

The measurements are stored in POLAR subdirectory as files defined by filename (Autoname Root) and
progressive numbering.
These files can be recalled separately or one upon another by:
(T)ransfer (L)oad POLAR\*<right arrow>command.

NOTE: actual Stimulus Amplitude is setted on +/- 0.1 Volt. You can change the default value according your
measurement necessity. In the same way you can change of course any parameters setup.

For better details on MLSSA polar measurements see manual instructions.

NOTICE

Turntable electronic control (ET1.1) was designed for using in conjunction with MLSSA version 8.1A software and
following versions. Using older MLSSA version it is possible that turntable skips a rotation degree's step failing the
actual measurement.
Because MLSSA use the computer's clock to determine the duration of the TTL pulse (10 msec. see pag.59 on 8
version manual) that drive the turntable, if the computer's internal clock is flaky then the pulse width will easy vary
and when the duration of the pulse is too short, less then 2 msec.
For this reason the ET1.1 control has some problem to recognise the incoming signal from MLSSA board, so the
turntable skips the step corresponding to the too short pulse received.
Because it is very difficult to make the turntable's control circuit able to accept a wide range of pulse duration
starting from the shortest pulse that are too much similar to noise ( to which the turntable control must be
insensitive), to avoid problem with some computers, DRA, consulted by OUTLINE, has already change the
software using the internal clock on MLSSA board that control with accuracy the duration of TTL pulse without any
computer's clock dependence.

- CLIO Applications –

The CLIO standard software includes the POLAR measurement menu.

With this integrated environment it is possible to execute
automatic polar plots at specified measurement frequencies, with
direct turntable control. Refer to CLIO User’s Manual (Section

11.6) for all the necessary information.
When the QC software version is used it is also possible to
program the QC processor to control two turntables thus
executing automatic measurements, over a full or half space, in
order to obtain, with ulterior post processing, 3D polar plots. The
two following scripts are needed and serve as a starting example
for this particular test environment:

Important note

ST2 turntable has been developed to support max. 300 Kg weight loaded on the centre of gravity with not more
then 30 Kg twisting moment. It can be also loaded, for example fixed under the ceiling with 100 Kg hanging under
the turntable plate with the same twisting moment. Take care in handling and laterally moving very high weight on
the turntable's rotating plate; it can happens to break some cogs of the internal motor reduction gear. To avoid this
please keep the plate fixed during the loudspeaker loading.
