The DBK214 module is compatible with the following products:
DaqBook/2000 Series DaqBoard/2000 Series DaqLab DaqScan
Overview
The DBK214 module includes:
o P1, male DB37 connector for Analog Input.
o P2, male DB37 connector for Digital I/O.
o P3, male DB37 connector for Pulse/Frequency (Digital and Counter/Timer) I/O, and
Analog Output.
o P4, 100-pin connector. Provides same signal connection as P1, P2, and P3 combined.
o 14 on-board screw-terminal blocks (accessible after removal of cover)
o The terminal blocks tie in to P1, P2, P3, and P4 and provide for easy signal connection.
o 8 BNC connectors (BNC0 through BNC7) for Analog Input
o 8 BNC connectors (BNCA through BNCH), custom configured by user for accessing
Analog I/O, Digital I/O, or Counter/Timer signals.
o On-board socket locations for custom RC Filter networks (accessible after removal of cover).
DBK214 Rear Panel
Upper section includes P2 and P3 DB37 connectors.
Lower section includes P1 DB37 connector and P4 100-pin connector.
The three DB37 connectors (P1, P2 and P3) can be used as direct connection points for I/O signals.
Optionally, convenient removable DB37 connectors [provided] can be used. Often signals are connected
to P1, P2, and/or P3 via cable and a DBK card or module.
The DBK214 provides BNC and screw-terminal access to all analog and digital I/O from the host data
acquisition device. Related to the screw-terminals is a front panel slot for routing all I/O wiring.
