Details
This command connects a device to another device through the LAN interface. If the
portNumber
is
23, the interface uses the Telnet protocol and sets appropriate termination characters to
communicate with the device.
If a
portNumber
and
initString
are provided, it is assumed that the remote device is not
TSP-enabled. The Model DMM7510 does not perform any extra processing, prompt handling, error
handling, or sending of commands. In addition, the
tspnet.tsp.*
commands cannot be used on
devices that are not TSP-enabled.
If neither a
portNumber
nor an
initString
is provided, the remote device is assumed to be a
Keithley Instruments TSP-enabled device. Depending on the state of the
tspnet.tsp.abortonconnect
attribute, the Model DMM7510 sends an
abort
command to the
remote device on connection.
You can simultaneously connect to a maximum of 32 remote devices.
Example 1
instrumentID = tspnet.connect("192.0.2.1")
if instrumentID then
-- Use instrumentID as needed here
tspnet.disconnect(instrumentID)
end
Connect to a TSP-enabled
device.
Example 2
instrumentID = tspnet.connect("192.0.2.1", 1394, "*rst\r\n")
if instrumentID then
-- Use instrumentID as needed here
tspnet.disconnect(instrumentID)
end
Connect to a device that is
not TSP-enabled.
