30    Sequoia Series 
connecting the instrument directly to the PC LAN port you will need a special cable called a cross 
connect cable.  Once connected you must establish an IP address for the instrument. An IP address 
consists of four groups of numbers separated by a decimal. Dynamic Host Configuration Protocol 
(DHCP)  is  typically  the  easiest  way  to  configure  the  instrument  for  LAN  communication.  DHCP 
automatically assigns a dynamic IP address to a device on a network.  You will need to enter the IP 
address on the Interface screen of the GUI to control the power source. 
The GUI has a built-in utility that lets you determine the IP address assigned by the network DHCP 
server. To use the LAN option, CI Virtual Panels GUI V1.1.5 or higher is required. The latest CI Virtual 
Panels  GUI  can  be  downloaded  from  the  California  Instrument  web  site.

If the IP Address of the Sequoia unit is known the IP Address can be entered manually in the IP 
Address Box in the Device Interface screen.  Another option if IP address is not known use the “Search 
Lxi Inst.” button on the Device Interface screen to bring up the IP address for the attached Sequoia 
unit.  Highlight your device and click “Connect” button to connect to Sequoia unit.
