Overview of Digital I/O
The 1100R+ has
Digital I/O
capability, which allows you to setup the tester to control external
devices with tester functions. You can also use an input on tester to start a test.
For example, the tester could be built into a cabinet that does not allow the operator to access
the display. By using the
External Switch
input, you can allow the operator to start a test with a
switch on the outside of the cabinet. Additionally, if the cable doesn’t pass the test, you can use
two of the tester’s outputs to activate a buzzer and a red light.
The digital I/O port is located on the back of
the tester. The location and pin out of the
connector are as shown.
The table below shows each of the signals on
the digital I/O port.
