Communication
Depending on the command line arguments /s, /t, /i, /AutoID, /NoAutoID,
/FallBack, the firmware starts several servers to handle SCPI commands.
(Refer the table above.)
/s, /t, /i: If -1, don’t start the respective servers
• Defaults:
• Socket port: 5025 (e.g. TCPIP0::localhost::5025::SOCKET)
• Telnet port: 5024
• HiSLIP, VXI-11.3: 0 (e.g. TCPIP0::localhost::hislip0::INSTR,
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
firmware 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 M8121A
module, first try to use the command line arguments /s, /t, /i or their
respective default values if they are not specified. If starting the servers
fails, proceed with the steps below.
• /s, /t, /i are ignored (unless they are -1 and a server is disabled)
• If the firmware 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 firmware uses always the same VISA
resource string per module
/NoAutoID Disable the default behavior; i.e. do not automatically select ports and
number for the connections.
/FallBack Try to find unused ports and number if starting a server fails.
/r resourceName Visa PXI resource string of the module to connect to, e.g.
PXI12::0::0::INSTR
