Loopback testing Digi Connect WAN,  Digi Connect SP, Digi Connect Wi SP, ConnectPort WAN and ConnectPort X4/8 units using connect

Loopback Testing:

1. Plug the DB9 loopback plug into the serial port to be tested (a loopback plug is shipped with every Digi unit).


2. From the Windows CMD or a Unix/Linux "root" prompt, telnet to the IP address of the Digi device server.

An example is: telnet

Login as root

3. From the root prompt set the port to a passive profile, such as, Realport or Console_Management. We will use RealPort and a device which only has one serial port in our example:

#> set profile profile=realport

#> who

ID  From                   To                     Protocol              Sessions

--  ---------------------  ---------------------  --------------------  --------

1   serial 1               local shell            term


Look for any active serial connections and kill them using the ID number.  In the above example, there is a connection on serial 1 with an ID of 1:

#> kill 1

4. Enter connect 1 (one) to connect to the first serial port.

5. Start typing characters on your keyboard. The characters you type should display on your PC monitor (once). If you remove the loopback plug from the port and type data on the connect session, you should not see any data on your screen.

To disconnect from the port, type: Ctrl-[ . (Control right square bracket, followed by a period).
