TCP/IP  
Configuration 
 
 
Function  Both Ethernet 10 /100/1000BASE-T interfaces can be used to link the gas analyzer 
to an Ethernet network (with TCP/IP protocol). 
 
The first Ethernet interface is referred to as X9 and the second one as X8. 
 
Parameters  The parameters to be set depend on the DHCP (Dynamic Host Configuration 
Protocol) setting: 
 
DHCP on:  Device name (max. 20 characters, no blanks and special characters),
DHCP off:  IP address, IP address mask und IP gateway address. 
 
Addresses  IP address, IP address mask and IP gateway address should be obtained from the 
network administrator. 
 
 
• Addresses of TCP/IP classes D and E are not supported. 
 
• The address bits that can be varied in the address mask cannot all be set to 0 or 
1 (broadcast addresses). 
 
Note  The IP address must not be mistaken for the Ethernet hardware address (or MAC 
address). The world-wide unique 12-digit MAC address is stored on each network 
board by the manufacturer. It is termed Ethernet address in the AO2000 series gas 
analyzers and can be viewed in the Diagnostics/Information → System 
overview → SYSCON menu item.
