Measurement Computing DBK32A - Manual (Page 3)

Connecting the DBK32A
The DBK32A can be installed into the internal expansion slot of a DaqBook/112, DaqBook/216,
DaqBook/2000X, a 3-Slot DBK10, a 3-slot DBK60, or a 10-Slot DBK41. It can also be used in a
LogBook/360 and DaqBook/260.
Examples of DBK32A Connections
If you will be using a 3-port DaqBook, i.e., DaqBook/100, /120, /200, /260, or /2000 Series
with a DBK41, then the best location for the DBK32A is the right-hand end-slot of the
DBK41 when facing the DBK41’s rear panel. This will be the left-hand slot if facing the
DBK41 from the front-panel.
DBK32A’s P1 Connector
DBK32A’s DB37 P1 connector interfaces with the analog DBK in one of two ways:
a) Via a P1 interface backplane, such as in the case of installing the DBK32A in a DBK41.
b) Via a CA-37-x cable, which interfaces between the DBK32A’s P1 connector and the P1
connector(s) of the analog DBK(s) that it is to supply power to.
DBK32A’s DIN5 Connectors
The DBK32A can be powered from a 9 to 18 VDC source such as an AC/DC power adapter, a DBK30A
battery module, or a car battery.
The DBK32A has two DIN5 power connectors to allow for the cascading of multiple DBK32As
(via a CA-115 power cable). The lower right-hand section of the preceding figure portrays this scenario.
Note that a DBK32A can share a power source with an acquisition device. For example, you can connect
a CA-115 power cable to the DIN5 Power Out connector of a DaqBook, DaqBoard, or LogBook and then
connect the other end of the CA-115 cable to one of the DIN5 connectors on the DBK32A.
DBK32A’s J1B Terminal Block
Terminal block J1B has one positive (+) and one negative (-) screw terminal. The terminal block power
connection is available as an alternative to a DIN5 connector. As indicated in the block diagram on page 1,
all three connectors are in parallel.
