Hi:
I have a RF switch connected to a remote PC (host PC) via ethernet connection. I need to control the RF switch from a client PC within the same subnet with the host PC. I am using NI Visa Server to establish the link between host and client PC.
First I tried using NI MAX explorer to try control from the client PC.
As you can see below, I can send query command to the RF switch.
But when I click the Validate button on the NI MAX explorer, I received Visa error 0xBFFF0011 "Insufficient location information or the device or resource is not present in the system."
I am getting the same error when I tried to do it in C# 2005 using the below code. I tried both methods below all did not work:
this.session = new TcpipSocket(remoteAddress + "::" + address + "::" + port + "::sOCKET");
this.session = new TcpipSocket(remoteAddress + "::" + address + "::" + port + "::sOCKET",AccessModes.ExclusiveLock,10000,false);
the address argument is = VISA://192.168.135.203/TCPIP0::192.168.2.170::7::sOCKET
192.168.135.203 = IP address of host PC (TXPTEST43)
192.168.2.170 = static IP address of RF switch
The RF switch is connected to the host PC via a USB to LAN port adaptor on the host PC.
I have no problem to access the RF switch using C# 2005 if the RF switch is connected to the same PC. The address will become:
TCPIP0::192.168.2.170::7::sOCKET
Note: the S of the SOCKET I have to use small case, otherwise it will turn into a smiling icon
Any help is appreciated.
Thank you.
