Abstract

A cable arrangement for loop circuits provides for easy device to device connection and minimizes confusion for operators that are not technically oriented by including both transmit and receive conductors in each cable link of the loop (each cable section extending between devices).

Simplified Cable Connection of Loop Communications Circuit

A cable arrangement for loop circuits provides for easy device to device connection and minimizes confusion for operators that are not technically oriented by including both transmit and receive conductors in each cable link of the loop (each cable section extending between devices).

Referring to the figure, a master device 10 includes an asymmetrically shaped receptacle 12 with sending and receiving terminal pairs 16 and 18, respectively. The asymmetry serves to assure a particular orientation for connection so that connection reversals do not occur. A first peripheral device 20 includes an asymmetrical receiving receptacle 22 having a pair of receiving terminals 24 and a set of pass through terminals 26. The pass through terminals 26 are connected to a corresponding pair of terminals 28 of a transmit receptacle 30 which also includes a set of transmit terminals 32.

A single multi conductor cable assembly 34 connects the master device 10 to the first peripheral device 20 and includes corresponding asymmetrical connectors 36 and 38. A similar cable assembly 34 may connect to a subsequent peripheral device 20 on the loop which would include similar receptacles 22 and 30. The cable 34 would connect between the transmit receptacle 30 of device 20 and the receive receptacle 22 of the subsequent peripheral device 20. The loop expansion may continue with additional peripheral devices 20. For the last peripheral...
