Problems
4.1
Driver malfunction
If the USB driver was not installed completely, the device may be reconized by the PC but the
application software could not access it.
Also is is probably not possible to reinstall the driver.
This can happen if the installation procedure was interrupted or cancelled by the user.
In this case, connect EasyLase II to the PC and go into the hardware manager of your system.
Select the EasyLase II device (or unknown device) and deinstall it.
Remove the USB cable and reconnect it.
The system should now recognize the device as new hardware and driver installation can begin
again.
4.2
Laseroutput is half size only
Check the connection of the ILDA cable.
Probably the minus-signals of X and Y are not connected or may be grounded at the laserprojector.
If you try to control a scanner having single ended inputs (Input+ and GND only), this will show the
same effect.
4.3
No function when running showsoftware
Check if the device is connected and powered.
Start the Testsoftware coming on CD. When the device is found and all functions work, check if the
DLL Jmlaser.dll or the driver Jmlaser.mld (for Mamba) is located in the right directory of the
software. Check if the output of the software is enabled and if the right output device is selected.
4.4
Software or hardware crashes during operation
Check the USB connection.
Check also the function of the USB-sockets. Some cheap cables can make bad connections.
If noise on the mains power could be the source of the problem (when powering-on other devices),
use EMI-filters for your powersupply. Use highquality USB-cable only.
Do not place the EasyLase II card or box near strong radiation sources, like transformers,
dimmerpacks or power-cables of other lighting equipment.
When mounting the OEM-card into a housing by yourself, a metal housing is suggested.
If you use the isolated DMX-option, you must use an external powersupply, because power
consumption of Easylase II could be too much for the USB port.
4.5
Output starts flickering and shows bright or blanked points or lines
Reduce output speed in your laser software.
The maximum output speed of 110Kpps may not work if the used PC is too slow or multiple
EasyLase II devices are used. If all 6 colour channels are used, maximum speed will be reduced to
about 80-90Kpps.
