Front Panel Push Buttons

4. Loop Select

The Loop Select button is used to select the port that is to be looped. It will cycle through the four ports, causing the respective ports Test LED to flash.

When a loop is in place, pressing this button will turn the loop off.

5. Loop Local

When a port has been selected using the Loop Select button, pressing the Loop Local button will initiate a loop on the selected port of the local NTU-45.

When a loop is in place, pressing this button will turn the loop off.

6. Loop Remote

When a port has been selected using the Loop Select button, pressing the Loop Remote button will initiate a loop on the selected port of the remote NTU-45.

When a loop is in place, pressing this button will turn the loop off.
