Connector Pins, Bank Elements, and Signals

Signal banking requires standardized translations between connector pin numbers and bank element letters, and between bank element letters and signals. This translation is defined for several connector and signal types in the Connector Pin to Bank Element Translation Table and Bank Element to Signal Name Translation Tables.

As shown in the following examples, the translation of connector pins to bank elements is connector specific. Pin 7 on the 10-pin connector in Figure 2, Connector Pin-to-Signal Translation on Single-Bank Connector, translates to bank element F, while pin 18 on the 44-pin connector in Figure 3, Connector Pin-to-Signal Translation on a Multiple-Bank Connector, translates to bank element F of bank 1.

By contrast, the translation of bank elements to signals is independent of connector type. For example, bank element F on both connectors corresponds to signal 2- for differential analog I/O bank types and signal 5 for single-ended digital I/O bank types.

Taken together, this means that any standard connector is generally interchangeable with another (or group of others) in a predictable way, regardless of the signal on each bank. Refer to Figure 4, Equivalent Connector Groups.
