Communication Configuration 
Presented here are three connection choices for remote control of 
the instrument: 
  through a local area network (LAN) 
  direct to a PC 
  through a private network. 
Each requires an IP address; the LAN also requires a Gateway 
address. The addresses can be set automatically through a 
Dynamic Host Configuration Protocol (DHCP) server or set 
manually with a static IP address. 
LAN Connection 
Connect the instrument directly to a network Ethernet port with a 
LAN cable, and allow the DHCP server to automatically assign a 
dynamic IP and Gateway address. If DHCP is not enabled, see the 
section on SETTING LAN PARAMETERS in this chapter or 
contact your network administrator. 
Direct-to-PC Connection 
Connect the instrument directly to a PC LAN port with a crossover 
cable (similar to an Ethernet cable but wired differently to enable  
direct connection rather than through a network). Next, establish 
an IP address for the instrument. You can assign a static IP address 
by using the same address as the PC that the instrument is 
connected to. To find the PC’s IP address, use the “ipconfig.exe” 
command per in the section on Private Network Connection next. 
Figure 6-6 shows the connection between the ENET unit and Local 
Computer through a crossover cable.
