IOLAN SDS/SCS/STS User’s Guide, Version 3.6

Communication Issues

General communication checks and practices are as follows:

z

Are 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.

z

Ping your host? If you can ping but packet loss is reported, ping another host/device on the same
network. This will tell you whether the problem is specific to the host/device or general to the
network.

z

After entering or changing IP information for your IOLAN, reboot the IOLAN (does not apply
when using BOOTP or DHCP). Once the IOLAN has rebooted, other network devices should be
able to communicate with it (ping, telnet, etc.). Also, protocols such as ARP and proxy-ARP will
work properly.

z

Use the

show routes

command (command line only) or view the

Routes

statistics. Is there a

route to the host?

z

If 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 may 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.
