Appendix B:Troubleshooting and 

Support

 

 

First Steps

 

1

 

Configure the unit with the correct settings. Follow the procedure in the figure on 
the following page (B-2) to troubleshoot Configuration screen access. 

2

 

Ensure that you are using the correct serial cables and that all cables are properly 
connected and in good working order. 

-

 

If you are connecting the iPocket

232

 to a DTE (Data Terminal Equipment) 

device or using it as a modem replacement, use an RS-232 serial cable. 

-

 

If you are connecting the iPocket

232

 to a DCE (Data Communication 

Equipment) device, use a null modem serial cable. 

3

 

If you know the IP address of the unit, you can check the network connection by 
pinging the unit. (See Check IP Address (Ping) on page B-3.) 

4

 

Check the indicator lamps on the front panel of the unit and use the indicator 
lamp tables in this appendix to diagnose the problem. 

5

 

If, after following the suggestions in this guide, you are still having problems 
accessing configuration or gaining connectivity, you can contact iPocket232.
