8.4.2. CONFIGURING THE ETHERNET INTERFACE OPTION USING DHCP 
The Ethernet option for you M300E/EM uses Dynamic Host Configuration Protocol (DHCP) to configure its 
interface with your LAN automatically.  This requires your network servers also be running DHCP.  The analyzer 
will do this the first time you turn the instrument on after it has been physically connected to your network.  Once 
the instrument is connected and turned on, it will appear as an active device on your network without any extra 
set up steps or lengthy procedures.   
NOTE 
It is a good idea to check the INET settings the first time you power up your analyzer after it has been 
physically connected to the LAN/Internet to make sure that the DHCP has successfully downloaded the 
appropriate information from you network server(s).   
The Ethernet configuration properties are viewable via the analyzer’s front panel.

PROPERTY DEFAULT 
STATE 
DESCRIPTION 
DHCP STATUS 
On Editable 
This displays whether the DHCP is turned ON or OFF. 
INSTRUMENT 
IP ADDRESS 
Configured by 
DHCP 
EDIT key 
disabled when 
DHCP is ON 
This string of four packets of 1 to 3 numbers each (e.g.  
192.168.76.55.) is the address of the analyzer itself. 
GATEWAY IP 
ADDRESS 
Configured by 
DHCP 
EDIT key 
disabled when 
DHCP is ON 
A string of numbers very similar to the Instrument IP address 
(e.g.  192.168.76.1.) that is the address of the computer used by 
your LAN to access the Internet. 
SUBNET MASK 
Configured by 
DHCP 
EDIT key 
disabled when 
DHCP is ON 
Also, a string of four packets of 1 to 3 numbers each (e.g.  
255.255.252.0) that defines that identifies the LAN to which the 
device is connected.   
All addressable devices and computers on a LAN must have the 
same subnet mask.  Any transmissions sent devices with 
different subnet masks are assumed to be outside of the LAN 
and are routed through a different gateway computer onto the 
Internet. 
TCP PORT1
1
 3000 
Editable, but 
DO  NOT 
CHANGE 
TSP listening port 1.  This port is used for standard Ethernet 
communications. The number defines the terminal control port 
by which the instrument is addressed by terminal emulation 
software, such as Teledyne API’s APICOM. 
TCP PORT2
1
 520 
Editable, but 
DO  NOT 
CHANGE 
TSP listening port 2.  This port is reserved for the M300E/EM 
Analyzer’s optional Modbus
®
 capability. The number matches 
the default address specified by Modbus
®
  specifications. 
HOST NAME 
DEFAULT = 
Model Type  
Editable 
The name by which your analyzer appears when addressed by 
other computers on the LAN or via the Internet.  While the 
default setting is the model type 
(e.g. M300E, etc.) the
 host 
name may be changed to fit customer needs. 
ONLINE ON Editable 
Enables or disables the M300E/EM Analyzer’s two TCP Ports.  
The TCP ports are inactive when this is set to OFF. 
DO NOT CHANGE the setting for this property unless instructed to by Teledyne API’s Customer Service personnel.
 
 
NOTE 
If the gateway IP, instrument IP and the subnet mask are all zeroes (e.g.  “0.0.0.0”), the DCHP was not 
successful in which case you may have to configure the analyzer’s Ethernet properties manually. 
See your network administrator.
