are summarized in Table 3-2, utilize a round cable as-

Since comections to external circuiq are made at the
96-pin male DIN bulkhead connector, there is no need
to separate the connector card from the relay card. If Table 3-2

Card Connections & hstahtion
Pins of the Model 7011-C mass termination connector can be identiiied in one of three ways:
1. Mux terminal, consisting of banks A-D and inputs l-10.
2. Connector description. consisting of rows a-c and columns l-32.
3. Schematic and component layout designation (l-96).
The following pinout diagrams show the correspondence between these arrangements:
