Connecting DBKs to a DaqBook/2000 Series Device via P1, P2, and/or P3
The DBKs do not connect directly to the port, but through a CA-37-x ribbon cable, where “x” indicates the
number of expansion devices that can be connected. For example, a CA-37-3 cable includes a 37-pin mating
connector to interface with the DaqBook/2000 Series DB37 connector (P1, P2, P3); it also includes three
additional DB37 connectors. These provide a means of adding three DBKs to one port. Use of a
CA-37-16 cable will allow up to 16 DBKs to be added to one DaqBook/2000 Series device DB37-type port.
Connecting DBKs to a DaqBook/2000 Series Device via P1, P2, and P3
The P4 connector on a DaqBook/2000 “AEX” device shares signal connections with the
P1, P2, and P3 connectors. P4 offers no additional I/O. Connecting a DBK200 Series
Option to P4 via a CA-195 cable distances the P1, P2, P3 connection from the
DaqBook/2000 Series device. It does not provide any new signal I/O. See the following
Caution.
CAUTION
Signal conflicts between a DaqBook/2000 “AEX” device’s P1, P2, P3 connectors and its
P4 connector can result in erroneous readings and possible equipment damage.
Therefore, when connections have been made to P1, P2, and/or P3, use caution when
making connections through P4, and visa versa.
The following pinouts indicate the P1, P2, and P3 pins, and their P4 equivalents.
Use the pinouts to avoid making duplicate signal connections.
