Card Connections and Installation
3-4
Keithley has a variety of cable and connector accessories
available to accommodate connections from the connector
card to test instrumentation and DUTs (devices under test).
In general, these accessories, which are summarized in
Table 3-2, utilize a custom-built cable assembly for
connections.
Typical connection technique
All external circuitry, such as instrumentation and DUTs,
that you want to connect to the switch card must be termi-
nated with a single 96-pin female DIN connector. The fol-
lowing connection techniques provide some guidelines and
suggestions for wiring your circuitry.
WARNING
Before beginning any wiring pro-
cedures, make sure all power is
off and stored energy in external
circuitry is discharged.
WARNING
When wiring a connector, do not
leave any exposed wires. No con-
ductive part of the circuit may be
exposed. Properly cover the con-
ductive parts, or death by elec-
tric shock may occur.
CAUTION
The 7011-MTC-2 cable is not
intended to be used with the
Model 7036. Pins 1 and 33 in the
cable are internally shorted, but
the Model 7036 uses these pins
for signaling. Using the 7011-
MTC-2 cable with the Model 7036
will short out the system and
cause equipment damage.
NOTE
It is recommended that external cir-
cuitry be connected (plugged in) after
the Model 7036 is installed in the Model
7001/7002 mainframe. Installation is
covered at the end of this section.
In Figure 3-2, connections are accomplished using a custom-
built cable assembly that consists of a Model 7011-KIT-R
connector and a suitable round cable. Hitachi part number
N2807-P/D-50TAB is a round, 50-conductor cable. Two
cables can be used to provide 100 conductors. The connector
has solder cups to accommodate the individual wires of the
unterminated cable. Figure 3-3 provides an exploded view of
the connector assembly and shows how the cable is con-
nected. For further Model 7011-KIT-R assembly informa-
tion, refer to the packing list provided with the kit. The
connector end of the resultant cable assembly mates directly
to the multi-pin connector card. The unterminated end of the
cable assembly is wired directly to instrumentation and
DUT.
