Troubleshooting

4. Enter Your Configuration

Initial Main Menu

From this index screen, you can select a section on the left and will be taken to configuration screens for 
each router subsystem.  

5. Minimum Configuration

The minimum configuration items required for basic operation are:

1. IP address appropriate for your LAN.

2. Serial port configuration appropriate to communicate with your serial device.

Configure these items and the EtherPath is ready for use. 

Help Screens  and Field Edits

In addition to the "HELP" button on the main screen, the field names on all configuration screens are 
hyperlinks to context sensitive help screens.  Simply click on the field name to bring up a second window 
with the help information.  Close that window to return to your entry screen.
