Setup and Startup 2-3
JP2 –
DAC Reference Voltage and SSH (Simultaneous Sample and Hold)
JP2 selects an Internal ( default ) or External reference voltage for the two separate
analog outputs.
JP2 also selects SSH ( default ) for applications using one or more of the following:
DBK2, DBK4, DBK5, DBK7, DBK17, DBK50, or DBK51.
We recommend that you leave these jumpers at the factory default setting
(see figure at right). Refer to the JP2 material in chapter 3 prior to making
changes.
CAUTION
Incorrect jumper placement can damage the DaqBook!
JP2 – If EXT DAC0 or EXT DAC1 are used, the SSH jumper must be removed!
JP3 and JP4 - Placing JP3 [or JP4] jumpers horizontally can damage DaqBook!
JP3 –
Bipolar or Unipolar A/D Operation
JP3 selects Bipolar ( default ) or Unipolar operation for the A/D converter.
•
If using DBK cards , leave these jumpers in the factory default positions.
•
If you want 0-10V range [instead of –5 V to +5 V] and are not using
DBK cards , position JP3 jumpers to select Unipolar .
Note : For DaqBook/200, /216 and /260 a JP3 equivalent setting is made in
software.
JP4 -
Single-ended or Differential Analog Input Channels
JP4 selects the analog input lines as 16 Single-Ended channels (default);
or 8 pairs of Differential channels.
If using DBK cards , leave these jumpers in the factory default positions.
If you are not using DBK cards and you want differential channels, then position
the jumpers for Differential.
Note : For DaqBook/200, /216 and /260 a JP4 equivalent setting is made in software.
