Set the LAN Subnet Mask
If communication between the client computer and the Product passes through a
router or gateway, and DHCP is disabled, it is necessary to set the subnet mask
and default gateway address on both the client computer and the Product. Get
the correct subnet mask and gateway address from the network administrator.
The LAN Subnet Mask is a 32-bit number. This number is represented as four 3-
digit segment numbers on the front-panel display. The default subnet mask set at
the factory is 255.255.254.0.
To change the Product subnet mask:
1. Do steps 1 and 2 from Select the Dynamic Host Configuration Protocol
(DHCP).
2. Touch Subnet Mask.
3. Use the numeric keypad to enter the subnet mask and then push Done.
If you make a mistake when the subnet mask is entered, push Cancel and go to
step 4 to enter the address again.
Read the MAC Address
The MAC Address is set at the factory and cannot be changed. The MAC
address can be read from the Ethernet Setup menu. The MAC address can also
be accessed with a remote connection that uses the MACADDR? remote
command.
Establish an Ethernet Connection
Telnet is the easiest method of establishing an Ethernet connection with the
Product, and Telnet is a client-server protocol, based on TCP. The Telnet
Protocol provides a fairly general, bi-directional, eight-bit byte oriented
communications method. Telnet is available on all UNIX servers and on most
PCs.
Telnet clients typically connect to hosts on socket port 23. The LAN connection to
the Product must be established with the specified Network Socket Port. See
Configure the General Network Socket Port. When the remote interface port is
changed to LAN from the Product front panel, a LAN server is initiated in the
Product that listens for client connections on the socket port at the specified IP
address.
To establish a LAN connection to the Product from a computer with either UNIX,
LINUX, or MS-DOS command prompts:
1. Touch Setup Menu>System Settings>Remote Port>Ethernet Setup to get
to the Ethernet Setup menu.
2. Touch Setup Menu>System Settings>Remote Port and change Active
Remote Port to Ethernet if necessary. At the command prompt on the client
computer, enter:
telnet <IP Address> <Socket Port>
As an example, if the IP address is known to be 129.196.136.131 and the
Socket Port is set to 3490, at a command prompt from any client computer,
enter:
telnet 129.196.136.131 3490
