### Testing the Terminal Connection: No Data

Use this troubleshooting procedure if the device is not receiving data and you need to test the terminal connection.

Procedure

1. Disconnect the dumb terminal and install a loopback plug.
2. From the UNIX root prompt for each port, enter:

> > `date >/dev/tty01`

> > where `date` is merely a command used for a this simple test to provide text output (there is no other significance) and `tty01` is the port to which the terminal is connected.

3. If the date appears, choose Back to return to the Master Troubleshooting Process.

> If the date does not appear on your screen, check the power, cables, connections and so on. If you still cannot get the date to appear, contact Digi Technical Support.
