Soft Front Panel
Communication
Depending on the command line arguments /Socket, /Telnet, /Inst,
/AutoID, /NoAutoID, /FallBack, the Soft Front Panel starts several servers
to handle SCPI commands. (Refer to the table above.)
/Socket, /Telnet, /Inst, /HiSLIP
: If -1, do not start the respective servers
Defaults
:
• Socket port: 5025 (e.g. TCPIP0::localhost::5025::SOCKET)
• Telnet port: 5024
• HiSLIP: 0 (e.g. TCPIP0::localhost::hislip0::INSTR)
• VXI-11.3: 0 (e.g. TCPIP0::localhost::inst0::INSTR)
/FallBack
: If starting a server fails because of a conflict, try using another
port or number
• HiSLIP, VXI-11.3: increase the index until a server can be started
successfully
• Socket, Telnet: start with port 60000, then increase it until the servers
can be started successfully. If neither socket nor telnet is disabled, the
Soft Front Panel tries to start the servers on two consecutive ports
(socket port = telnet port + 1)
/AutoID
: Automatically select ports and number for the connections,
which are unique per instrument.
This is the default behavior; it is not necessary to specify this argument on
the command line.
If only one AXIe module is connected to this PC and it is an M8132A
module, first try to use the command line arguments /Socket, /Telnet,
/Inst, or their respective default values if they are not specified. If starting
the servers fails, proceed with the steps below.
/Socket, /Telnet, /Inst, /HiSLIP are ignored (unless they are -1 and a
server is disabled)
If the Soft Front Panel detects more than one AXIe module, use a special
mechanism to obtain a number for the HiSLIP and VXI-11.3 servers, which
makes sure that the Soft Front Panel uses always the same VISA resource
string per module
The socket and telnet port are then calculated from the HiSLIP index:
• telnet port = 60000 + 2 * <HiSLIP index>
• socket port = 60000 + 2 * <HiSLIP index> + 1
