Configuring an Ethernet connection 
Menu path 
MENU → Configure → System → Network → TCP/IP Network 
 
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 which have to be input depend on the DHCP setting: 
DHCP on: Network name (max. 20 characters, no blanks and special charac-
ters), 
DHCP off: IP address, IP address mask and IP gateway address. 
Addresses 
The IP address, IP address mask and IP gateway address must be obtained 
from the system administrator. 
NOTES 
Addresses of TCP/IP classes D and E are not supported. 
The address bits that can be varied in the address mask may not all be set to 
0 or 1 (broadcast addresses). 
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.
