8.1.2 IP Information
This is where the CXC’s current IP Address Settings are displayed for the LCD menu. Scroll bars enable the user
to navigate the list of text items for viewing; i.e., IP Address, Subnet Mask, Gateway, and Ethernet/MAC Address.
For the web interface, the current IP Address Settings are found by clicking on the “View Live Status” link of the
Communications submenu.
8.1.3 Configuring IP Address Settings
This section discusses how to change CXC communications parameters in the IP Address section of the menu
(or web interface). See 6.8.3 and Figure 83. To save changes, refer to Section 4.9.
8.1.3.1 Obtain Address Automatically
If selected, this checkbox will enable the CXC to automatically obtain an IP address from a
DHCP server at system boot-up (if checked it will enable the DHCP client protocol).
8.1.3.2 Static Settings
All three fields in this area are only enabled if the “Obtain Address Automatically” checkbox is
not selected.
IP Address
This field is the Static IP Address to use for the CXC device. The format of the IP address must
be a so-called “dotted quad” – that is a series of 4 values in the range 0-255 each separated by
a period. For example, an example of a dotted quad would be: “192.168.1.23”.
An incorrect example would be: “213.12.24.264” (264 is outside the range 0-255).
NOTE: The rules and restrictions for valid IP addresses are beyond the scope of this manual.
Check with the LAN administrator for details.
Subnet Mask
This field contains the dotted quad for the static Subnet Mask for the CXC.
Gateway
This field contains the dotted quad to specify the gateway to use for routing packets if the
destination IP address is not local.
8.2 PPP Connection Devices
One of two PPP Connection devices can be selected from a pull-down menu for HTTP web server connection:
Front Craft Port or Rear Modem Port (Figure 100). PPP connections over serial ports are mutually exclusive to
each other.
NOTE: The PPP connection for HTTP web server connection has no effect on enabling the HTTP web server for the
Ethernet port. The HTTP web server for the Ethernet port cannot be disabled.
8.2.1 Front Craft Port
Front Craft Port does not support modem connection. For most CXC models, it is used with NULL modem
connection for HTTP web server connection.
CAUTION
For the CXCI, do not connect anything other than the Alpha modem and Alpha-supplied DB-9
cable to the D-sub port on the front.
