Pb communication TCP/IP avec un oscillo Lecroy 6100 et librairie Visa

[Thez]

Hello,

I am trying to communicate with a remote Lecroy 6100 scope through TCP/IP, using the visa library.
I have configured my device with MAX but it can not
open an INSTR session. I have check the IP address, my
device respond to a ping. I have installed a VisaServer
on my device but from my PC, no INSTR session can be
opened.
Does someone have any idea ?
Thank you.

Hello,

First of all, I advice you to use the instrument driver for your device:
* WR 6100 - WaveRunner 6000 series Oscilloscope
http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/DF35A33EF5129A8586256E920052E226?OpenDocument#rank

NI-VISA 2.5 (and higher), on Windows32 platforms only, allows you to connect to ethernet instruments via TCP/IP. This is done by specifying a TCP/IP Instrument (INSTR) Resource or TCP/IP Socket (SOCKET) Resource. The syntax for each is as follows:

TCPIP[board]::host address[::hostname][::INSTR]
To use the INSTR resource type, the device must support the TCP/IP Instrument Protocol, also known as VXI-11.

TCPIP[board]::host address[::host name]::port::SOCKET
The SOCKET Resource exposes the capability of a raw ne
twork socket connection over TCP/IP (usually, but not restricted to, an ethernet interface). Without TCP/IP Instrument Protocol support, you must use the SOCKET resource type.

If there is only one interface type present on the host machine, then the board type is optional. For example, "TCPIP0::..." is the same as "TCPIP::...", because 0 after TCPIP is optional. Also, host name has to be used only when there is more than one hostname (instrument) in the host address.
