Trigger input for event triggering. This trigger inputs 
are connected directly to the DSP signal processor. 
 
Input Signal : Negative slope 
 
Input   Function          Remarks 
Trigger IN 1 :  Wave start 
Trigger IN 2 :  Wave stop 
 
Trigger output for event triggering. This trigger 
outputs are generated from the DSP signal 
processor. 
Max. voltage:  24 V ( pull up ) 
Current :  100 mA 
 
NOTE :  For use the trigger out the user must connect 
an external DC source for pull up the trigger 
signal. If no external dc source is available, a 
T-connection to Trigger IN will deliver the dc 
signal. 
The network controller supports a 10 / 100Base-
Tinterface. The device auto-negotiates the use of a 
10 Mbit/sec or 100 Mbit/sec connection.

USB port for data transfer to or from a memory stick. 
 
The power contacts for USB devices are not protected. They are 
suitable to supply connected USB devices with a maximum of 500 
mA  power  dissipation.  Don’t  supply  external  USB  devices  with 
higher power dissipation through this interface.
