Installation guide
Setting up a LAN Instrument Network  16 
Since the default IP address is a local address, it will not be routed 
by any network device. Thus, the PC and the card must reside in the 
same subnet. 
The user may open a Telnet session using the default IP address and 
change the parameters stored in the non-volatile memory of the 
card. He may then close the session, select the initialization mode 
“Using Stored”, power-on again and establish the TCP/IP connection 
using the new parameters. 
When the card is wired to the PC directly, separated from the local 
area network, the user may simply keep the default parameters to 
establish the TCP/IP connection. 
Storing Settings Permanently with Bootp Program 
Change the parameters of the J4100A Jet Direct and 1369A/B card 
using Bootp by following the instructions below: 
1.  Turn off the instrument that hosts the Jet Direct card and 
remove the card. 
2.  Change the card’s settings of the Configuration Switch to”Bootp & 
Store” mode. 
3.  Install the Jet Direct card. 
4.  Start the Bootp program and open its window. 
5.  If required, modify the parameters for the Jet Direct card. 
6.  Now turn on the instrument with the Jet Direct card and view 
the Bootp program window. The parameters are now stored 
permanently in the non-volatile memory of the card. 
7.  Close the Bootp program and turn off the instrument and 
remove the Jet Direct card. 
8.  Change the settings of the card’s Configuration Switch to “Using 
Stored” mode. 
9.  Install the card and power cycle the instrument with the Jet 
Direct card. The instrument can be accessed now via LAN 
without the Bootp Server program. 
Assigning IP addresses permanently with Telnet 
The IP address can be set by opening a Telnet session for any Jet 
Direct card except the J2552A/B card (BootP required).
