Once you have created a remote GPIB or remote serial interface in Connection Expert, you can use ordinary GPIB or serial addressing in your VISA or VISA COM programs to address instruments on these interfaces. The Remote IO Client software maps TCPIP address requests into appropriate interface type (GPIB or ASRL) addresses; thus the IP address and hostname of the E5810 do not appear in the instrument address. This makes it possible to use existing programs written for GPIB or ASRL without having to modify code.
See “Configuring a Remote GPIB Interface” on page 66 or “Configuring a Remote Serial Interface” on page 68 to configure a remote GPIB or remote serial interface. VISA programs can then use addresses such as GPIB0::22::INSTR (for GPIB) or ASRL1::INSTR (for
viOpen (...”GPIB0::22::INSTR”...) viOpen (...”ASRL1::INSTR”...)
Although remote GPIB and remote serial interfaces are the most convenient way to configure and program instruments on your E5810, you may choose not to use them. For example, if you are using another vendor’s I/O software rather than the Agilent IO Libraries Suite, your I/O software probably does not support remote interface addressing. (At the time of this writing, only Agilent software supports remote interface types.)
If you are not using remote interfaces, you will address your instruments as TCPIP resources in VISA. These addresses include the IP address or hostname of the E5810 as well as the SICL address of the device on the E5810.
Use these addresses in your viOpen() call as follows. These examples assume that the VISA interface ID of your TCPIP interface is “TCPIP0”. (You can specify this interface ID with the Connection Expert utility; “TCPIP0” is the default VISA ID for the default TCPIP interface.)
viOpen (...”TCPIP0::my_IP_address::gpib0,22::INSTR”...) viOpen (...”TCPIP0::my_IP_address::COM1,488::INSTR”...)
