Abstract

An arrangement is illustrated in Fig. 1 for assigning a unique address identifier to units of a data processing system which permits the user to make the assignment with a minimal possibility of error. Figs. 1a and 1b illustrate a cardholder which is built into the machine and adapted to receive one of the identifier cards shown in Figs. 2a and 2b. The cardholder comprises a suitable card frame 10 for holding the card in an upright vertical position, as shown, and includes a plurality of switch contacts 11 which are selectively separable by the edge 13 of card 14. The switches may be coded to represent a digit and the digit displayed prominently on the card. The card edge 13 is coded appropriately with the correct digit.

Visually Indicating Identification Assignment Switch

An arrangement is illustrated in Fig. 1 for assigning a unique address identifier to units of a data processing system which permits the user to make the assignment with a minimal possibility of error. Figs. 1a and 1b illustrate a cardholder which is built into the machine and adapted to receive one of the identifier cards shown in Figs. 2a and 2b. The cardholder comprises a suitable card frame 10 for holding the card in an upright vertical position, as shown, and includes a plurality of switch contacts 11 which are selectively separable by the edge 13 of card 14. The switches may be coded to represent a digit and the digit displayed prominently on the card. The card edge 13 is coded appropriately with the correct digit. The code may be based on either the switch contacts that are opened by insertion of the card or the switch contacts that are not open when the card is inserted. One set of cards, for example, 0-7, would be supplied with the eight units of a system. If desired, a unit may employ more than one card where it has a 2-digit identifier. Alternately, one card may be arranged both from its visual indication and its coded assignment to represent different numbers for each side of the card which are code complements of each other.
