4. A tester unit for testing a patch cord having plugs at opposite ends and a pair of conductors interconnecting the plugs comprising:
-
a housing and battery means mounted within said housing having positive and negative poles, a pair of jacks mounted on wall portions of said housing, each accessible to a plug inserted thereinto exteriorly of the housing, each jack having a first contact for making contact with one type of contactor in the plug of a patch cord and a second contact for making contact with another type of contactor in the plug of a patch cord, a pair of signal devices mounted on wall portions of the housing discernable from the exterior of the housing, and conductor means within said housing establishing, for at least one jack, a series connection between one pole and one of the contacts of the jack and a series connection between the other pole, a signal device and the other contact of the jack, said conductor means further establishing, with the plugs at the opposite ends of a patch cord properly received by the respective jacks, and with the pair of conductors in of the patch cord having proper integrity, a series connection between the poles of the battery means which includes one conductor in the patch cord and one signal device, and a series connection between the poles of the battery means which includes the other conductor of the patch cord and the other signal device.
