Notes: 
(1)  Daq PC Card users: With exception of pins 11 through 18, and 30 through 37, users of the Daq PC Card 
should 
not refer to this pinout; instead, refer to the Daq PC Card user’s manual. 
(2)  SSH is “Simultaneous Sample and Hold.” 
(3)  Software configuration commands determine P1 digital I/O pin functions.
(4)  Refer to the user’s manual of the applicable primary data acquisition device for more additional information. 
(5)  For devices that have 100-pin P4 connectors DBK200 Series adapters can be used to obtain one or more DB37 
connectors designated as P1, P2, and P3.
