Measurement Computing PC104-DAS08 - Manual (Page 10)

2 SIGNAL CONNECTIONS
2.1 CONNECTOR DIAGRAMS
The PC104-DAS08 analog connector is a 40-pin header connector.
The connector accepts female 40-pin
header connectors, such as those on the
C40FF-2, 2 foot cable with connectors.
If connector compatibility with a
CIO-DAS08 is required, the C40-37F-#
or BP40-37 adapter cables can be used.
The C40-37F-# cable converts the
signals on the 40-pin header into the
standard DAS08 37-pin, D connector
pin assignments. If a connector on a
standard PC bracket is required, the
BP40-37 adapter cable can be used to
convert the 40-pin female header to a
37-pin male mounted on a bracket. See
Figure 2-2 for the BP40-37 pinout.
Figure 2-1. Analog Connector
Figure 2-3 shows the cabling of the
BP-40-37..
If frequent changes to signal
connections or signal conditioning is
required, please refer to the
information on the CIO-TERMINAL
and CIO-MINI37 screw terminal
boards, CIO-EXP32, 32 channels
analog MUX/AMP or the
ISO-RACK08, 8-position 5B module
interface rack.
