Connecting the TB-2705 to an E Series or Waveform Generation Device

Caution

The TB-2705 is not designed for input voltages greater than 42 V, even if you 

install a voltage divider that reduces the voltage to within the input range of the DAQ 
device. Input voltages greater than 42 V can damage the TB-2705, any device connected 
to it, and the host computer. Overvoltage can also cause an electric shock hazard for the 
operator. National Instruments is 

not 

liable for damage or injury resulting from such 

misuse.
