Using the LAN’s X Window Interface

To start the interface from the computer

1 On your Xserver, enable analyzer-initiated windows.

Most Xserver packages have a security feature which stops unwanted

client-initiated windows from being displayed.

On computers running the UNIX operating system, you can enable

analyzer-initiated windows by entering the xhost command:

xhost +<analyzer IP address>

On computers that aren't running the UNIX operating system, the

Xserver package documentation will explain its security features.

2 Send the XWIN ON programming command to the logic analyzer.

The syntax of the XWIN ON command is:

xwin on,"<Xserver IP address>:<display>.<screen>"

The IP (Internet Protocol) address is the address of the XWindows

server.

There are several methods for sending the XWIN ON command. The

easiest is using psuedo-telnet, but it can also be done using ftp or

writing to the NFS-mounted logic analyzer. See the following examples.

Example NFS method using a UNIX computer

To enable windows to be initiated from the logic analyzer named

lp1670G, enter the following command on the computer running the

Xserver:

xhost +lp1670G

If you have NFS mounted the analyzer's file system to a directory

named /logic on your computer whose IP address is 15.6.253.146 (and

is running the Xserver), enter the following command to start the

XWindow interface:

echo "xwin on,'15.6.253.146:0.0'" > /logic/system/
