6.2.7 Setting the COM46 User Configuration Options
The information shown in Figure 34 below is one of the subsections available on the Advanced
Edit page.
Figure 34 – “User Config” Interface on Advanced Edit page
This section gives you the ability to customize select features of the COM46 cards to better suit
your application. The cards actually support a few more features than shown here, but the two
most useful features have been made available here. You have the ability to set the IP address
the card uses or to change the mechanism the card uses to obtain IP addresses. You can also
control and configure the sending of log data to a PC or other monitoring mechanism via the
Ethernet.
Following is a brief explanation of each field shown above.
IP_Config – This field allows for one of 3 methods of IP address assignments to be chosen. The
default IP_Config setting is 0.
0 = Default
In this mode the IP address is assigned to the card based on the chassis ID and slot the card is
currently in. The formula for this address is 192.168.3.[1 + (chassis ID X 16) + slot number]
Example: chassis ID = 1 slot = 1 Default IP address = 192.168.3.1 + 16 + 1 = 192.168.3.18
Example: chassis ID = 1 slot = 6 Default IP address = 192.168.3.1 + 16 + 6 = 192.168.3.23
Example: chassis ID = 2 slot = 1 Default IP address = 192.168.3.1 + 32 + 1 = 192.168.3.34
Example: chassis ID = 2 slot = 6 Default IP address = 192.168.3.1 + 32 + 6 = 192.168.3.39
In the Default IP mode the Base_IP and the Gateway fields are ignored. The Subnet field is also
ignored but the Subnet mask is set to 255.255.0.0 and is applied.
