Multifunction DAQ Cable and
Accessory Selection Guides
NI Cable Design Advantages
The SH68-68-EP cable is the most commonly used E Series and
S Series cable. The cable is designed to work specifically with the
NI Multifunction DAQ devices to preserve signal integrity through
these technologies:
Seperate digital and
analog sections
Twisted pairs for
critical digital I/O
Individually-shielded
twisted pairs for
all analog inputs
Large (20 AWG) conductor
for +5V Lines
Figure 2. NI offers a wide variety
of cable and accessory options,
such as the SH68-68-EP cable
and the BNC-2110 terminal block.
Double ground shield
PVC jacket
Individually-shielded
analog outputs

1Unshielded cables can cꢀnnect tꢀ shielded accessꢀries and vice-versa. 2In adꢅacent PCMCIA slꢀts, bꢀth cables types are required because the same cable wꢀuld cause mechanical hindrance.
