1 Description
The Lasershow-outputboard EasyLaseUSB II allows the control of ILDA-compatible
lasershowprojectors over USB by using different Showsoftware.
There is no need for installing cards into PC-slots and Notebooks can be used to playback
lasershows.
A driver-DLL with open documented API allows to use the board with self-written showsoftware.
All output signals for the laserprojector are symmetrical and are located at an ILDA-standard
connector.

Starting up
If EasyLase USB II is powered using an external powersupply, use regulated DC powersupply only.
The device works with voltages from 8V to 24 V.
It is recommended to use powersupplies which are well immunized against power line transients
or to use power plugs with integrated EMI-filters.
For enhanced reliability during operation, the use of a high-quality USB2.0-cable (double shielded
with integrated EMI-filters) is suggested
Lowquality-cables can cause malfunction of hardware and software.
Each device comes with a CD-ROM, containing documentation, drivers and test software.
.1 Handling instructions Boardversion (OEM-Version)
When the device is used as open board version (OEM), it should be taken into account, that the
device is sensitive object. Static discharge and other external influence can damage electronic
components on the board.
The device can also be damaged by applying external voltage to signal pins, by wrong connections
and other kind of manipulation. Watch for correct connection of signals and careful handling.
The manufacturer excludes liability in case of damages as result of unproper handling, wrong
signal connection and unspecified working conditions, unless it is verifiable that damage
existed when the product left factory.
Also any liability claims regarding damage caused by the use of this product will be rejected.
. Step-by-step driver installation
Important!
Each device, which is connected to the USB-port of the PC for the first time, needs a driver
installation. Also an installation will be necessary, when the USB-port for connecting the device
will be changed (depends on operating system).
Using multiple devices, it is recommended to use the same port for the same device all times to
avoid driver reload.
When installing the first device, it is necessary to locate the driver files on the data media (disk, CD-
ROM). When installing additional devices, the option 'automatic installation' of the driver
installation wizard can be selected.
The driver can be installed directly from CD, but it is suggested to locate the driver files in a
directory of the harddisk.
Copy the file 'EasyLase.dll' into the directory, where the executable file of showsoftware is located.
If you want to remove the device drivers, deinstallation has to be done in the systemmanager.
Connect the device to the USB-port. When using external powersupply, switch it on.
The green LED 'Power' and the red LED 'Active' must be lighted.
Wait until the following message appears.
Do not disconnect the device and do not close/cancel any messages of your PC.
4
Windows will recognize the device after a few seconds and will open the installation dialog:
If you are asked to search the Internet for drivers, select 'no'!
if you install your first EasyLase USB II, do not use the automatic installation option.
and then continue
If you have already installed an EasyLase USB II on this PC, you can select automatic installation.
The following step will be skipped then.
5
Now choose the drive and directory, where the driver files are located
If you want to install from the CD, choose
Confirm with
Windows will search the driver and install it.
After installation is complete successful, confirm with finish
Now the device should be listed in the hardware manager as USB Laser Device:
By clicking the right mouse button to the entry 'EasyLase II' and then click on 'properties', the device
information will be displayed. Here you can see the version information.
Also you can do a firmware update here, if necessary.

.3 Use new DLL with older software
The DLL 'Jmlaser.dll' which acts a bridge between your application software and the hardware
driver, was designed to be compatible with older software.
If you use a software which uses the old 'EasyLase.dll', the use of the new dll normally would not be
possible.
But the new Jmlaser.dll contains all functions to control also older devices.
The new DLL contains all functions (calls) of
•EasyLase USB old version
•NetLase
•EasyLase USB II
•EasyLase USB LC
•Phoenix Live Interface
If you use a software which uses the old EasyLase device, just rename the new DLL Jmlaser.dll to
'Easylase.dll' and replace the old file 'Easylase.dll' with this file.
Your software now will support the old EasyLase hardware as well as the new EasyLase II. (and
also all other devices listed above).
Note:
If your software does not work with a specific product, the reason can be that the manufacturer of
this software excludes the use of a specific hardware.
The new DLL contains various license functions.
For example, the software 'LDS Nano' will not accept any other hardware except 'EasyLase LC'.
Special Note for Software Mamba:
Mamba does not need a specific name of the DLL.
So you can use the file 'Jmlaser.mld' coming with the CD of EasyLase II (or rename 'Jmlaser.dll' to
'Jmlaser.mld').
Note that all older device-DLLs, like 'EasyLase.mld' or 'NetLase.mld' have to be removed from the
Mamba directory. Otherwise a collision between new and old device-dlls will happen.

3 Signal connectors (see Fig.1)
3.1 Connecting Scanner- and Colorsignals
All signals are located at anILDA-standardconnector. This can be a 25pin D-Sub-connector (female)
or a 2 pin IDC-connector, when the device should be mounted in a projector directly.
The IDC-connector allows to connect a separate D-Sub connector by using a flat cable.
All pins are routet 1:1, except pin 2 , which has no function. Note the different pinnumbers of the
connectors. The wirenumber of a flatcable, starting with 1 at pin 1 corresponds to the pinnumber of
the DSUB connector (see table below).
Signals for X, Y and up to 5 colours + intensity are available.
Colour output is internally connected to output intensity.
All colour outputs are single ended signals, referred to GND.
The maximum signal level is 5.2V (measured against GND).
Outputs X/Y are symmetrical, using a maximum voltage level of +/-5V per output pin.
This gives a total maximum output voltage of +/-10V between the signal pairs (+) and (-).
Important! Never let one half of the signal pair unconnected.
If one part of the signal pair (+) and (-) is used only, maximum deflection angle of the scanner or
laser projector will be the half value only. Same happens if one of the signals will be connected to
GND.
Always connect the GND-pin (Pin 5 of the DSUB-connector) to your laser projector.
Question: Why are the signals of the new device different to the ones of the old EasyLase?
Answer: The floating signals of the old Easylase allowed higher flexibility in use but created many
misunderstandings and problems with the users.
The new signal specification is easier to use, even with laser projectors which don't have a full
wired ILDA-connector.

* Signals Intensity and Colour Cyan are connected on board. The software must decide, if 5 colours
plus an intensity channel or colours are used.
Note: When using 5 colours + intensity, the th colour signal (Cyan) must be ignored.
When using colours without intensity, the signal at the Intensity pin must be ignored.
** Caution: Shutter output maximum load current is 20mA!
