Abstract

In the transmission of data from a master to a slave machine, it is often necessary to test the master by transmitting the data out of the machine and cabling it back into test circuits in the same machine. For example, in data transmission over a telegraph or telephone line, it is necessary to simulate at one terminal the functions of receiving as well as transmitting. In order to carry out this self test, the cable is disconnected from the transmission line and connected to a dummy plug on the machine to obtain the proper test connections. This often involves considerable inconvenience such as withdrawing the cable through a duct, etc. This connector permits such testing without this inconvenience.

Block 10 is essentially a multi contact connector having pin contacts 11 which mate with contacts 12 in line terminal block 14.

The wires of machine cable 15 would normally be connected to pins 11. However, in this device they are connected through a rotary switch
16. The switch is preferably one in which a brush 17, of which there is more than one, completes a circuit between opposing contacts such as 18 and 20. Arm 21 is secured to the brushes 17 by which they, are rocked to a position between contacts 22 and 23.

In the wiring diagram, opposing contacts are diametrically opposite one another and the brushes are two ended. In the position shown, wires 24 of cable 15 are connected through contacts 18, brush 17, and contact 20 to pins 11 of the line t...
