Measurement Computing CIO-EXP-GP - Manual (Page 8)

If the range on your A/D board is fully programmable, the software you use for measurement will
determine the range.
3.4 CONNECTING THE CIO-EXP-GP TO THE A/D BOARD
3.4.1 Connecting to a DAS08 Series A/D Board
A CIO-DAS08 series board may be connected directly through a C37FF series cable from the P1
connector on the CIO-EXP-GP to the A/D analog connector. The JB10 jumper should be left in the
DAS08 position as set at the factory.
3.4.2 Connecting to a DAS16 Series A/D Board
Connection to a DAS16 series board requires a special 37-conductor cable (CEXP2DAS16-10) since pin
relationship of CIO-EXP and DAS16 signals is not 1:1.
Install the CEXP2DAS16-10 cable connector labeled “MUX” into the P1 connector of the CIO-EXP-GP
board and the other end into the DAS16 series board’s analog connector.

For other boards, use the connector diagram in
Figure 3-4 to construct a cable, or call us and
discuss the possibility of a custom
manufactured cable.
The signals from the CIO-EXP-GP are
voltages from each channel and an analog
ground. There should be no voltage between
the analog ground and the power ground.
The MUX address lines control the setting of
the channel multiplexer. When all are low, the
mux is set to channel 0. The lines are binary
coded. MUXADDR1 is the LSB and
MUXADDR3 is the MSB.
A jumper (CH SEL) selects which output
channel is read by the DAS08 or DAS16
board.
