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 2461 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 2461 sends an
abort
command to the remote
device on connection.
The Model 2461 also enables TSP prompts on the remote device and event management. The Model
2461 places remote errors and events from the TSP-enabled device in its own event queue and
prefaces these events with
Remote Error
, followed by an event description.
Do not manually change either the prompt functionality (
localnode.prompts
) or show events by
changing
localnode.showerrors
or
localnode.showevents
on the remote TSP-enabled
device. If you do this, subsequent
tspnet.tsp.*
commands using the connection may fail.
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.
