EM1500 FAQ
Q:
Why was the connection refused when I tried to telnet to my EM1500?
A:
This could happen for various reasons. Here are some things to check:
Did you use a valid IP address? Did you include the correct TCP port number? If the answer
to both of those questions is yes, do you have DHCP checked? If you do, the IP address may
have changed. Uncheck “Use DHCP” and try again.
If you are telnetting from a remote location, did you assign a router for the EM1500?
Q:
What do I do if my EM1500 is behind a firewall?
A:
There should be no problem getting the EM1500 to connect out through the firewall, only
incoming network connections may be affected. In that case, you will either have to be behind
the same firewall, or work with your network adminstrator to punch a hole through it.
Q:
Help! I assigned an invalid IP address to the EM1500 and I can no longer talk to it. What
should I do?
A:
First, don’t panic. You can recover from this without losing your configuration settings. You
must do a hard reset of the EM1500 back to its factory default condition. Do this by holding
the reset button down for at least 10 seconds. This causes all configuration parameters to reset
to factory defaults on the EM1500. After the reset you will see a red exclamation point next
to the entry of the EM1500 in the stand-alone configuration program. The program has
noticed that the settings it has for the EM1500 are different than those on the actual unit. If
you want to keep the default settings, then press <Ctrl+Z>. This will undo all the settings you
entered in the stand-alone program. If you want to keep the settings you entered in the stand-
alone program, enter a valid IP address (or check “Use DHCP” if that is the method you are
using to assign an IP address) in the “Network” tab and save the changes by pressing
<Ctrl+S>.
Pressing either <Ctrl+Z> or <Ctrl+S> will cause the red exclamation point to disappear,
indicating that the configuration information from the EM1500 and in its entry in the stand-
alone program both match.
