8.1.2 IP Information
Displays the CXC current IP Address Settings 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
Communications > View Live
Status .
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
Selecting this checkbox enables the CXC to obtain an IP address automatically 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 se-
lected.
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).
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 con-
nection: Front Craft Port or Rear Modem Port (Figure 100). PPP connections over serial ports are mutu-
ally exclusive to each other.
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
The 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 a CXCI controller, do not connect anything other than the Alpha modem and Alpha-sup-
plied DB-9 cable to the D-sub port on the front.
