Typical connection techniques
All external circuitry, such as instrumentation and
DUTs, that you wish to connect to the switch card must
be terminated with a single 96-pin female DIN connec-
tor. The following connection techniques provide some
guidelines and suggestions for wiring your circuitry.
WARNING
Before beginning any wiring proce-
dures, make sure all power is off and
stored energy in external circuitry is
discharged.
It is recommended that external cir-
cuitry be connected (plugged in) after
the Model 7013 assembly is installed
in the Model 7001 mainframe. Installa-
tion is covered in paragraph 3.5.
Round cable assemblies Figure 3-5 shows typical
round cable connection techniques using accessories
available from Keithley.
In Figure 3-5A, connections are accomplished using a
Model 7011-MTC-2 cable and a Model 7011-MTR bulk-
head connector. The two-meter round cable is termi-
NOTE
nated with a 96-pin female DIN connector at each end.
This cable mates directly to the multi-pin connector
card and to the bulkhead connector. The bulkhead con-
nector has solder cups to allow direct connection to
instrumentation and DUT. Figure 3-6 provides pinout
for the bulkhead connector. The view shown is from
the solder cup end of the connector.
In Figure 3-5B, connections are accomplished using a
Model 7011-MTC-2 cable assembly that is cut in half.
The 96-pin female DIN connector on one end of the
cable mates directly to the multi-pin connector card.
The unterminated end of the cable is wired directly to
instrumentation and DUT. The other half of the cable
assembly could be used for a second switching card.
In Figure 3-5C, connections are accomplished using a
custom-built cable assembly that consists of a Model
7011-KIT-R connector and a suitable round cable. Hita-
chi part number N2807-P/D-50TAB is a round, 50-con-
ductor cable. Two cables can be used to provide 100
conductors. The connector has solder cups to accom-
modate the individual wires of the unterminated cable.
Figure 3-7 provides an exploded view of the connector
assembly and shows how the cable is connected. The
connector end of the resultant cable assembly mates
directly to the multi-pin connector card. The untermi-
nated end of the cable assembly is wired directly to
instrumentation and DUT.
