Using EXP-16 or EXP-16/A with KPCI-3108 Series
When an application calls for external multiplexing, the KPCI-3108 series of board should be used with the
EXP-1800 external multiplexer for best results. The EXP-1800 has very fast settling time capabilities and
can switch at the full speed rating of the KPCI-3108.
However, the KPCI-3108 does provide for upgrades from the DAS-1600 series systems. For those with
significant investment in signal conditioning designed for use with DAS-1600 (EXP-GP, EXP-16, etc), an
easy connection is provided to the KPCI-3108. Operational and performance differences need to be taken
into account in the system implementation.
Physical Connection
The STA-3108-A2 screw terminal panel for use with the KPCI-3108 Series provides a DAS-1600 Series
compatible male DB37 connector. For example, to connect to an EXP-16 or EXP-16/A see figure below:
Expansion Channel Addressing and Configuration
Expansion channel addressing should be enabled in the DriverLINX configuration for the KPCI-3108
series board. This will allow the auxiliary digital output bits on the upper, analog I/O connector of the
KPCI-3108 to control the channel addressing of the EXP-16 or EXP-16/A board automatically.
The analog input channels of the KPCI-3108 must be configured for 16 SE channels. Under DriverLINX,
these 16 channels are always 0 through 15. The 16 channels of an EXP jumpered to make use of channel 0
will be referenced as channels 16 through 31in software. The 16 channels of an EXP jumpered to make use
of channel 1 will be referenced as channels 32 through 47, and so on for additional EXP accessories.
Power Considerations
The EXP-16 requires power from 5VDC, +12VDC (or +15VDC) and
