the plastic wrapping, place the manual in the binder
following the mainframe instruction manual. Note that
a manual identiÞcation tab is included and should pre-
cede the matrix card instruction manual.

If an additional instruction manual is required, order
the manual package, Keithley part number 7012-901-
00. The manual package includes an instruction manu-
al and any pertinent addenda.

back of this manual.

1.9

Optional accessories

The following accessories are available for use with the
Model 7012:

Model 7012-ST



This screw terminal connector card

is identical to the one provided with the Model 7012-S
assembly. An extra screw terminal connector card al-
lows you to wire a second test system without disturb-
ing the wiring conÞguration of the Þrst connector card.

Model 7011-KIT-R



This connection kit includes a

96-pin female DIN connector that will mate directly to
the connector on the Model 7012-C or to a standard 96-
pin male DIN bulkhead connector (see Model 7011-
MTR). This connector uses solder cups for connections
to external circuitry. It includes an adapter for a round
cable and the housing.

Model 7011-MTC-2



This two-meter round cable as-

sembly is terminated with a 96-pin female DIN connec-
tor on each end. It will mate directly to the connector
on the Model 7012-C and to a standard 96-pin male
DIN bulkhead connector (see Model 7011-MTR).

Model 7011-MTR



This 96-pin male DIN bulkhead

connector uses solder cups for connections to external
circuitry. It will mate to the Model 7011-KIT-R connec-
tor and Model 7011-MTC-2 cable assembly.
