Removable Screw Terminal Block
Allows signal connections to be made to the DI-75B. The input signal connections are made along the top row while
the excitation connections (for those DI-5B modules that require excitation) are made along the bottom row. Note that
this screw terminal block can be removed from the DI-75B, thus making signal connections to the screw terminals
easy. Note also that the screw terminal block is “keyed,” thus difficult to improperly re-insert. Each channel (labeled
“CHANNEL 1,” “CHANNEL 2,” etc. on the socketed backplane) has four corresponding screw terminals for your
signal connections: c, channel -, exci, and excitation -. These terminals satisfy all transducer inputs
and provide sensor excitation when necessary.
POWER switch
Controls power to the DI-75B. 1 is on, 0 is off.
POWER input jacks
The DI-75B-7 can be powered by its host instrument through the supplied dual-ended power cable. Simply unplug
the five-pin DIN end of the power adapter cable that is currently supplying power to your host instrument and plug it
into one of the DI-75B's power input jacks. Now plug one end of the dual-ended power cable into the remaining
power jack on the DI-75B and plug the other end into the host instrument power input jack.
POWER status lamp
Glows green when the POWER switch is in the 1 position, indicating power is applied to the DI-75B.
POWER LOW lamp
Glows red when the DI-75B cannot derive adequate power from its host instrument. In this case, an alternate power
source is required. Any suitable power source (+9 to +36 volts DC at 3A maximum) may be connected to either
power input jack to provide the necessary power.
EXPANSION OUT connector
Used to connect to a DI-705 in order to access the Digital I/O of the DI-715B. Connect the appropriate end of a
CABL-7 to this connector and connect the other end of the cable to the DI-705. See “The DI-705” on page 42 for
more information.
EXPANSION IN connector
Connects the DI-75B to its host instrument.
Configuring Channels for the DI-75B
In W
IN
D
AQ
Acquisition software, channels are enabled or configured for acquisition with the channel selection grid.
The channel selection grid is accessed by selecting Edit > Channels… (in the SET-UP operating mode of W
IN
D
AQ
software).
Each box in this grid potentially represents an input channel. An input channel is enabled by clicking the desired box.
Which box you click, which mouse button you click with, and how many times you click the mouse button deter-
mines whether the input channel is enabled for single-ended operation, or operation defined by the DI-5B module.
