Communication Issues

Communication Issues

General communication checks and practices are as follows:

zAre your cables connected and correctly configured? If you are using EIA-232, see EIA-232

Cabling Diagrams on page 356 to verify that your cables are correctly configured.

zPing your host? If you can ping bu t packet loss is reported, ping another host/device on the same

network. This will tell you whether th e problem is specific to the ho st/device or general to the

network.

zAfter entering or changing IP information for your IOLAN, reboot the IOLAN (does not apply

when using BOOTP or DHCP). Once the IOLAN has rebooted , ot her network devices should be

able to communicate with it (ping, telnet, etc.). Also, protocols such as ARP and proxy-ARP will

work properly.

zUse the show routes command (command line only) or view the Routes statistics. Is there a

route to the host?

zIf the WebManager or DeviceManager cannot communicate with the IOLAN, verify that the

Server Services HTTP and/or HTTPS are enabled for WebManager and DeviceManagerD is

enabled for DeviceManager. If you are using only HTTPS, the connection URL must start with

https://.

DeviceManager Problems

Error Message: 16 bit Windows Subsystem - C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The

system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose

'Close' to terminate the application.

The error message can be misleading, because it is displayed even if the AUTOEXEC.NT file is

actually missing.

To verify whether you have the file, type %windir%/system32/ in the address bar of an Explorer

window. If there is no AUTOEXEC.NT file proceed as follows:

1. Browse to %windir%/repair/ (usually C:\WINDOWS\repair).

2. Right-click and Copy the AUTOEXEC.NT file.

3. Browse to %windir%/system32/ (usually C:\WINDOWS\System32).

4. Right-click inside the window and Paste the file.

The error condition described here m ay also be the result of corruption of the AUTOEXEC.NT file, in

which case the above procedure may be helpful to restore a valid file.

If the above procedure does not fix the DeviceManager installation problem , see

http://support.microsoft.com/?kbid=324767 for the official Microsoft explanation.
