Safety instructions Safety symbols in the manual Indicates hazardous voltages. WARNING Calls attention to a procedure, practice, or condition that could cause bodily injury or death. CAUTION Calls attention to a procedure, practice, or condition that could possibly cause damage to equipment or permanent loss of data. WARNINGS The following general safety precautions must be observed during all phases of operation, service, and repair of this product.
Safety instructions Safety instructions for all DEWETRON systems The DEWETRON data acquisition systems may only be installed by experts. Read your manual before operating the system. Observe local laws when using the instrument. Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth terminal), a non interruptible safety earth ground must be provided from the mains power source to the product input wiring terminals or supplied power cable.
General Information CAUTION The system BIOS is protected by password. Any change in the BIOS may cause a system crash. When the system is booting, do not press ESC-button on keyboard. This may clear the BIOS settings and cause system faults. Any change in the file structure as deleting or adding files or directories might cause a system crash. Before installing software updates contact DEWETRON or your local distributor. Use only software packages which are released by DEWETRON.

DEWE-50-USB2-16 DEWESoft configuration • To configure your modules in the DEWETRON-system please install the software “DEWESoft” from your system-DVD and choose the option “DEWESoft for DEWEConfig mode” After the installation please start DEWESoft and enter the COM port where your modules are connected. (Note: Please don´t change the setting “Analog device” - it should be set to “No A/D Hardware”). Confirm the new settings with “OK”, exit this menu and choose “Setup”.
DEWE-50-USB2-16 DEWESoft licensing Enter in the hardware setup of DEWESoft the license keys from the license certificate you got with your DEWESoft. DEWESoft settings DEWESoft automatically changes to the multi-board-mode if it detects more than one device installed in the system. If you do not want to do this, it is possible to deactivate it in the DEWESoft tuner located in the DEWESoft directory. Also the master board can be changed there.

DEWE-50-USB2-16 Synchronisation of more than one DEWE-50-USB2-16 How does it work The synchronization of more than one DEWE-50-USB2 device is realized by using counter 0 of the master device for generating the sample clock for all devices. This includes the following limitations. The maximum sample rate is the half sample rate of the slowest device that is synchronized. The counter 0 of the master board could not be used for anything else.
