EM1500 FAQ
Q:
I can't see all of the configuration options mentioned in the manual. Where are they?
A:
You may need to enable advanced settings via View | Advanced. Advanced view enables the
Aux I/O, Polling and Protocol tabs.
Q:
In the Aux I/Os panel, I changed the settings and saved them to the unit, but the status panel
shows the outputs in the old state. Why did they not change?
A:
The Aux/IO settings are one of the few configuration items that are not changed until the unit
is rebooted. They are only checked at boot time to establish an initial state. The direction of
PF0-4 cannot be changed on-the-fly. If you really need to see the changes, press the red
"reset" button on the status panel. This reboots the unit. It will take a few seconds to come up
again.
Q:
Using a web browser, I changed some configuration settings. Now the browser is giving error
messages or timeouts. Why is the EM1500 broken?
A:
If you changed the IP address, netmask, or some other critical network parameters, then the
EM1500 restarts its network interface. This causes the browser to get confused, since it really
knows nothing about the IP address change. To fix this, just press the browser's "stop" button
(if necessary) then manually type in the unit's new IP address, e.g., "http://10.10.9.99". If the
new IP address is valid, the browser should be able to pick up from there. If this did not fix
the problem, see the next question.
Q:
I just changed some configuration items and sent them to the unit.The unit now seems to be
dead! Why is it broken?
A:
Most often, the cause of this is that some critical network configuration items were changed.
The EM1500 tries to action the new settings immediately. If the settings are inappropriate,
then the stand-alone program (or web browser) will lose communication with the unit. Here
are some common possibilities:
• The IP address is invalid for the network to which the EM1500 is connected.
• The netmask is too narrow (or broad) and either the EM1500 or the PC cannot accept
packets from the other. If both PC and EM1500 are on the same LAN, then the netmasks
for both should be the same, and the IP addresses of both should be in the same subnet.
• The IP address is already in use by another device.
• The EM1500 is remote (i.e. not on the same LAN) but there is no "router" defined for it to
be able to communicate back to the PC, or the router IP address was incorrect.
Note that sometimes the EM1500 with bad network parameters will show up in the list of
units, however it will not be possible to configure the unit or access its status.
