Figure 13 – Internet Protocol Configuration
In the window that you have just opened, you will see that there are two options available for
defining an IP address for your PC. If your system has a DHCP server, you may select the first
option,
“Obtain an IP address automatically
.
”
The benefit of this option is that it greatly
minimizes the chances that you will have duplicate IP addresses in your network. One potential
downfall of this choice, however, is that there is a chance that everything in your system could
be assigned new IP addresses at the next reboot. Unless you are using something like the
COM24.exe tool to resolve those addresses for you automatically, controlling the cards may
prove difficult once this happens. Refer to Section 5.1.6 above on how to resolve this issue.
If you wish to manually configure your network and ensure that you will never have to worry
about IP addresses changing on you, however, then select the second option,
“Use the following
IP address ,
”
taking care to assign a unique IP address to your PC. Also configure the subnet
mask to 255.255.0.0.You may not know the cards‟ IP addresses at this point, but it is very likely
that they will be using the factory default range of
192.168.3.18
to
192.168.3.29
, so any IP with
the same prefix should work. If, for example, you select an address of
192.168.3.249
for your
PC, you should generally be able to find the cards with a minimum of difficulty.
In addition, in order to successfully perform file transfers to your system (as required for
software upgrades), it is recommended that you give your computer an IP address that is in the
same subnet as your COM24 cards when using the manual configuration method. Configure
subnet route to 255.255.0.0.
