Card Connections & Installation

3-6

Terminal identification for the DIN connector of the multi-
pin connector card is provided by Table 3-3. This connector
will mate to a 96-pin female DIN connector.

Keithley has a variety of cable and connector accessories
available to accommodate connections from the connector
card to test instrumentation and DUT (devices under test). In
general, these accessories, which are summarized in Table 3-
4, utilize a round cable assembly for connections.

Notes:

1. Pins 9a and 9b (pins 9 and 41 on schematic) are shield.

2. Short pin 1a to 1b on the mating connector (pins 1 and 33 on schematic) to allow the output relays on the connector card to close.

Pins of the Model 7015-C mass termination connector can be identified in one of three ways:

1. Mux terminal, consisting of banks A-D and inputs 1-10.

2. Connector description, consisting of rows a-c and columns 1-32.

3. Schematic and component layout designation (1-96).

3.3.4 Multi-pin (mass termination) connector

card

Since connections to external circuitry are made at the 96-pin
male DIN bulkhead connector, there is no need to separate
the connector card from the relay card. If the connector card
is separated from the relay card, carefully mate them togeth-
er and install the supplied 4-40 mounting screw. Be sure to
handle the cards by the edges and shields to avoid contami-
nation.
