TEST PROCEDURE:
The MCT-7 Cable Tester is simple to operate. A schematic diagram of the
connectors and their pin assignments is shown on the front panel of the unit. Light
Emitting Diodes (LEDs) give a clear visual representation of the connections.
YELLOW LEDs 1-5 refer to the pins of connectors on the left side (INPUT) of the
unit. Green LEDs 1-5 refer to the pins of connectors on the right side (OUTPUT) of the
unit.
Checking the status of connections is made using the Pin Selector Switch. Until
you become familiar with the connectors, pin wiring and switch selector positions, you
may wish to refer to the data shown in Table 1.
