—array of length numSlots, use –1 for an empty slot,
0 for multiplex mode, 1 for parallel mode, and 2 for parallel mode
using the secondary connector of the DAQ device
•
DAQboards
—array of size numSlots, with 0 for all slots with no DAQ
device cabled to the module, and the MIO device number for the slot
containing the module cabled to the DAQ device
Verifying Adjusted Values
After completing the adjustments to the SCXI-1520, it is important that
you verify the analog input operation by repeating the steps listed in the
Verifying Gain and Offset Errors
sections. Reverifying after adjustments ensures that the SCXI-1520 is
operating within its specifications.
Front Signal Connector Pin Assignments
The pin assignments for the SCXI-1520 front signal connector are shown
in Table 1. The front signal connector is a special 96-pin DIN C male
connector through which you make all signal connections. The terminal
assignments are as follows:
•
S
X
+ and S
X
– are for analog input
•
RS
X
+ and RS
X
– are for remote sense
•
P
X
+ and P
X
– are for excitation output
•
SCA
X
are for shunt calibration circuit A
•
SCB
X
are for shunt calibration circuit B
where
X
is the channel number.
The negative terminals are listed in Column B and the positive terminals are
listed in Column C. The pins labeled RSVD are reserved. Do
not
make any
connections to these pins.
