SYSTEM DESCRIPTION

outline ET250R2-3D ET Series Electronic Turntable-fig2

Outline’s restless pursuit of perfection has resulted in the development of two new and improved ET Series products, building on the unparalleled worldwide success of our previous models during the last half century – we are very excited to unveil the brand new ET50-3D and ET250R2-3D.
As a result of years of study and tests, the mechanical sturdiness makes the ET250R2-3D turntable a real rugged tool able to support remarkable loads. The brand new ET50-3D, on the other hand, is designed to move lighter loads faster.
The combined use of two units, backed up by a suitable structure (see the example with the ET250R2-3D on page 13 of this manual), enables to obtain three-dimensional rotation, which is particularly useful to loudspeaker enclosure manufacturers, for example.
The microprocessor-based control unit guarantees utmost precision and, thanks to the network interface in compliance with Ethernet standard, enables the models to be completely controlled via PC. For this purpose, Outline supplies dedicated software that can control up to two units, commanding their synchronized movement.
On request, Outline also provides a dedicated DLL (Dynamic Link Library) for software developers.
For compatibility with some measurement cards on the market, the Outline turntables are equipped with an Input/Output port based on TTL signals through which it is possible to send the unit the rotation command and receive a return pulse when rotation ends.

UNPACKING

After unpacking the unit, check very carefully for any damage. If any damage is found, please notify your dealer. It is advisable to keep the packaging for use in the event of the unit being transported in the future. The Outline ET unit is supplied with the following accessories:

1 AC mains power cable
1 9-pin male Combicon connector and 1 9-pin female Combicon connector

INSTALLATION

MOUNTING
The Outline ET series was designed for horizontal, vertical and upside-down use.

HORIZONTAL USE
The ET250R2-3D and ET50-3D have been tested to support an axial load of 1,000 kg (2,200 lb) and 200 kg (440 lb) respectively. Prepare a suitable level support to ensure good operation of the unit and avoid it being damaged. The load shall be equally distributed on the plate surface.

UPSIDE-DOWN USE
The ET250R2-3D and ET50-3D have been tested to support an upside-down load of 200 kg (440 lb) and 40 kg (88 lb) respectively. Please note that the load, especially in this configuration, shall be equally distributed over the anchor points on the plate surface.

VERTICAL USE
The two models have been tested to support a maximum radial load of 250 kg, with a maximum bending moment of 500 Nm and a torque of 250 Nm for the ET250R2-3D; while the ET50-3D with a maximum bending moment of 50 Nm and a torque of 50 Nm. It is therefore necessary to check the loads that are applied, taking into consideration the distance of the centre of gravity of the load from the turntable plate.

THE MANUFACTURER DECLINES ANY AND ALL RESPONSIBILITY FOR ANY DAMAGE CAUSED BY INCORRECT USE OF THE UNIT OR FAILURE TO COMPLY WITH THE DECLARED PARAMETERS.

USE OF MOUNTING SCREWS

The Outline ET series turntables have fixing holes on the bottom and on the platter. The screws for the mounting holes on the top (rotating) side must be M8 (8.8) with an insertion depth between 30 mm to 40 mm from the plate surface. While for the bottom (fixed) side, M8 (8.8) screws must be used with an insertion depth between 18 mm to 23 mm from the base surface. Please, make sure the screws enter the platter or the base by at least the specified minimum value and do not exceed the specified maximum value. The maximum tightening torque is 20 Nm. Only the ET250R2-3D has a middle threaded M20 on the bottom which MUST NOT be used for fixing, but is designed for the eventual use of a counter weight.THE MANUFACTURER DOES NOT RESPOND FOR ANY DAMAGE CAUSED BY FAILURE TO OBSERVE THIS RULE.

REMOVING THE CONTROL ELECTRONICS

Like the previous version (Outline ET250-3D), the electronics of the new Outline ET series turntables are built into the body of the mechanism.
However, it is possible to separate the two parts, for example, installing the mechanism in a measurement room and the electronics in another remote control via network, as explained further ahead in this manual).
To extract the control electronics, just remove the two fixing screws on the front of the unit, then disconnect the cable on the rear of the electronics and fit an extension cable (made according to users’ needs) between the mechanism and the electronics.
To make the extension cable, use the two 9-pin Combicon connectors (one male and one female) supplied with the unit. Connect the two connectors in parallel, making certain to keep the same wiring sequence.
Attention: use a cable with a sufficiently large cross-section to avoid signal loss.
When using a cable run it is recommended to disable the acceleration flag. If long cable runs are required it is suggested to check the configuration with Outline’s technical department by sending an email to info@outline.it.

INSTALLATION PRECAUTIONS

Installation in excessively damp or dusty locations can cause damage to the unit or faulty operation.

MAINS CONNECTION
The Outline ET series turntables are fitted with a 3-conductor cable; the green-and-yellow wire of the mains cord must always be connected to anearth or ground. This is also necessary in the case of cable extensions, adaptation of existing mains sockets, adaptors, etc. This is essential for safety and correct system operation. Inside the unit, the yellow/green wire is connected to the metal chassis.

ATTENTION! THE UNIT MUST ALWAYS BE EARTHED.
THE MANUFACTURER DECLINES ANY AND ALL RESPONSIBILITY FOR ANY DAMAGE CAUSED BY FAILURE TO COMPLY WITH THIS RULE.

MAINS POWER VOLTAGE
The Outline turntables use a switching power system that ensures high efficiency and low heat dispersion. It accepts any input power voltage between 90V AC and 250V AC (nominal), without any adjustment being required. Outside this range the unit will not work correctly. If voltage exceeds the maximum limit, it will probably cause damage, whereas excessively low voltage will cause the system to shut down.

STAND-ALONE USE OF THE UNIT

The Outline ET series unit’s platter can rotate in both directions (clockwise and counterclockwise).
The minimum movement step is 0.5 degrees and is made by pressing the MANUAL buttons.
The STEP buttons on the other hand are used to rotate the platter with number of degrees that can be set. This value is 5 degrees by default, but can be changed using the STEP SETTING buttons. When pressed once, the stored value is displayed; each time they are pressed again raises or lowers the value by 0.5 degrees.
There is no absolute “zero” position. When the electronics are switched on, the current position is considered position “zero”. However, It is possible to set a new “zero” position, by keeping STOP/ZERO SET pressed for approximately 2 seconds.
The main function of the STOP/ZERO SET button is to immediately stop turntable rotation if necessary.

USE THE UNIT WITH TTL PULSE

There is a TTL SYNC connector on the front of the control electronics to use the turntable with some measurement cards. With a mini jack connector, it is possible to:

Send a TTL pulse (at least 5 ms) to the turntable (TTL INPUT) which starts rotation (only forwards) with the stored step. This action corresponds exactly to pressing the DEGREES UP – STEP button and allows the measurement card to start turntable rotation.
Receive a TTL pulse from the turntable (TTL output), which indicates that rotation is finished. The measurement card can thus proceed with another acquisition. To allow the load standing on the turntable to come to a complete standstill at the end of rotation, this pulse is generated after a delay that can be set from 1 to 9999 ms. Default value is 3,000 ms. To change it, press the two TTL DELAY SETTING buttons simultaneously: the delay value will be displayed in milliseconds. Press then MAN. buttons to increase or decrease the delay by 1 ms. Press the STEP buttons to increase or decrease the delay by 100 ms. After finishing setting, press the SAVE button to store the new value or the ESC button to abort modification procedure without storing a new value.

ATTENTION: To avoid damaging either the unit or the measurement card, connection must be carried out with both units switched off.

USE WITH ET COMMANDER SOFTWARE

The Outline ET series turntables is supplied with dedicated software for its complete control. This software can be used to control multiple turntables, specifying the various rotation modes.

INSTALLING THE SOFTWARE ON A PC

The software works on Windows operative systems and is available from Outline’s web site (www.outline.it) from the ET series page. Please download the zip file and extract it on your computer in any position (such as C:\temp, administrator rights might be required). Before using the software, configure the network.

NETWORK CONFIGURATION

Connect the Outline turntable to the ETHERNET network (using the RJ45 connector on the front).
The turntable uses UDP (User Datagram Protocol) network protocol, as per RFC 768 standard.
To enable several devices using this standard to communicate, each must have a valid and unique IP address.
The network address at which the unit is set before leaving the factory is:
- IP: 192.168.1.34
- SUBNET MASK: 255.255.255.0
- DEFAULT GATEWAY: 192.168.1.250
BROADCAST IP: 192.168.1.255
In order for the software to identify the unit on the network, the turntable and the PC must be part of the same sub network.
According to factory settings, one possible PC network configuration is:
- IP: 192.168.1.10
- SUBNET MASK: 255.255.255.0
Once the software has recognized the device, it is possible to change the network configurations.
To check the IP allocated to the Outline turntable, just turn it on by pressing and holdingdown the STOP button. The stored IP will appear on the display.
If using two Outline units, the IP address of at least one of them MUST be changed. To do this, turn on one unit at a time and change the IP address using the ET Commander software. No other device(s) with the same address(es) can be present on the same sub net.

USING ET COMMANDER SOFTWARE

Start the program by double clicking on the “ETcommander2012.exe” file.
Click on “Scan Net” to look for the connected turntable(s). A window will appear with a list of the network cards installed on the PC; select the one to which the turntable is connect.
Attention: Before running a scan, make certain the turntable is on.
Immediately after OK is pressed, the network is scanned to find any units.
The units found on the network will appear on the list. Click on one unit and click on “Show” in order to show the control panel of that specific unit (you can show at the same time multiple units).
From this panel it is possible to see the actual angle of the turntable, start and stop the turntable movement, change the description, enable or disable the “acceleration” feature and start a macro.
In order to move the turntable to a specific angle type the desired value in the “Move to (deg.)” area and click on the “Up” or “Down” arrows if you’d like to move to the desired angle increasing or decreasing the degrees (i.e. if you want to make a 180° rotation clockwise o counter-closckwise).
In order to move the turntable with an agular steps, write the step degrees value in the “Move step (deg.)” area and click on the “Up” or “Down” arrows if you’d like to move with the desired angle increment in the two directions.
The “Acceleration” flag enables the turntableto gentle start and stop. When the acceleration is active the turntable rotates at a lower speed at the beginning and at the end of the movement.
This feature might be used in order to have less “shocks”.
The turntables’ network settings (IP address) can be changed by selecting one unit at a time from the list and clicking on the “Network” button.

FOR SOFTWARE DEVELOPERS
Outline puts at the disposal of software developers a DLL for the total control of the ET series turntables and raw commands in case of specific control requirements. These details can be requested by sending an e-mail to info@outline.it.

MEASUREMENT EXAMPLE

One example of 3D use of the ET250R2-3D turntables is shown in the illustrations below, intended above all for loudspeaker enclosure manufacturers who need to measure their products’ acoustic dispersion.
With a suitable mechanical structure, it is possible to make the two turntables work in a coordinated manner: one mounted in a horizontal position and the other in a vertical position.
This enables a 3D polar measurement to be produced in a single work session, with an enormous saving of time and greater measurement precision.
