Measurement Computing DaqView - Manual (Page 19)

3. Select the applicable DBK card from the drop-down list.
If the card has jumper or switch setups that need to be set in DaqView, a related dialog box will
appear. Three extracted examples follow: (a) Switch Settings: S1 Sub Address, (b) Switch Settings:
SW6 (rotary), and (c) Shunt Settings: JP16 (3-pin shunt).

4. Set the software DIP-switch settings, shunt-settings, and so forth to match the hardware settings on the
actual DBK(s).
5. When all the channels and sub-addresses are set correctly, select OK to return to the DaqView main
screen.
6. From DaqView, complete the channel setup, acquisition setup, and data destination setup for each of
the new DBKs.
This completes the software setup for analog DBK options, with exception of the following special case
scenario pertaining to DaqBook/2020.
It is possible to have a situation similar to that
shown at the right where we see that the
descriptive text for External Connection P1
channels 0 and 1 is grayed-out (see area “A”).
However, the P1 Channel numbers are clearly
visible.
The reason, in this instance, is that we are using a
DaqBook/2020. For that device “P1-0” is being
used by the device’s internal circuitry for 16
differential voltage channels. These are the Direct
Channels that are listed on the main spreadsheet,
i.e., CH0 through CH15.
In addition, the device’s “P1-1” is being used by
its own set of 16 thermocouple channels. These
are the TC0 through TC15 Direct Channels listed
on the main spreadsheet.
In addition to indicating pre-assigned channels, the
Configure System Hardware
screen may display a
device-dedicated
GUI panel similar to that shown
at the right (see area “B” in the figure). In this
example [from a DaqBook/2020] checking the box
enables channel P1-2 through P1-15 to be added to
the channel scan list as direct connect channels. In
other words, the channels will appear on the main
window spreadsheet along with the P1-0 and P1-1
direct channels.
Analog I/O Expansion Supported, and
Pre-Dedicated Channels P1-0 and P1-1
In this DaqBook/2020 example analog expansion is
supported. However, notice that the first two
channels (designated by “A” in the figure) are
grayed-out. In this case 2 channels were pre-
assigned due to channel circuitry built-into the
device.
DaqBook/2020 uses P1-0 for 16 differential voltage
channels and P1-1 for 16 thermocouple channels.
These 32 channels are built-into the device, as
opposed to being obtained from an external DBK.
