Ethernet Interface Setup Guide

Ethernet terminology and default setup

For the printer to operate with Ethernet, a series of commands must be set within the printer. These commands can only be
set through the host computer and are not configurable through the printer configuration menu.
Default setup instructions and sample Ethernet diagnostic printout are on the following page. Note the differences between
an Ethernet and a standard RS-232C printout.
Ethernet Terminology
Before making command settings, review the following description of terms to fully understand their intended meaning.
a unique hexadecimal serial number assigned to each Ethernet network device to identify it on the
MAC address
network. Each printer communication board gets a unique number from CognitiveTPG's assigned range
of numbers. CognitiveTPG numbers start with: 00:E0:70.
a unique number that identifies each node on a network and to specify routing information. Each node
IP address
must be assigned a unique IP address. The address is made up of two distinct parts: a network ID,
which identifies the network; and a host ID, which is typically assigned by the administrator. These
addresses are typically represented in dotted-decimal notation, such as 138.58.11.27. The default setting
is: 192.0.0.192
a series of bits designed to "mask" certain portions of an IP address and is used primarily for subnetting.
Net mask
The standard netmask for a Class C network is 255.255.255.0, with the last octet (.0) directing the host
to look there for the machine number. The rest (255) is the network number. The default setting is
0.0.0.0. The net mask is used to determine if a gateway is needed to reach an address.
a hardware or software set-up that translates between two dissimilar protocols. A gateway, even when
Gateway
the printer is on another subnet, is not always needed. The printer initiates no connection and obtains
the gateway address from the host packets. The default setting is 0.0.0.0 (none)
an application protocol for connection to the Internet. With HTTP, the printer's Ethernet settings can be
HTTP
configured with a Web GUI. The HTTP server listens on port 80. The default setting is to have HTTP
enabled.
Raw TCP/IP Port enables the printer to listen for raw TCP/IP communications. Specifying this to zero will disable raw
TCP/IP connections. Default value is 9001 enabled.
DHCP allows "leasing" of IP address for a limited time. If no IP address is found at start-up, the printer
waits for two more minutes. If no address is found after two minutes DHCP will automatically set the
default IP address. Default: enabled
