Front panel operation
To reset the TSP-Link network from the front panel:
1. Press the Menu key, then select TSPLINK and press the ENTER key.
2. Turn the navigation wheel to select RESET and then press the ENTER key.
Remote programming
The commands associated with TSP-Link reset are listed in the following table.
TSP-Link reset commands
Command
tsplink.reset()
tsplink.state
An attempted TSP-Link reset will fail if any of the following conditions are true:
•
Two or more instruments in the system have the same node number.
•
There are no other instruments connected to the unit performing the reset (only if the expected
number of nodes was not provided in the reset call).
•
One or more of the units in the system is not powered on.
•
If the actual number of nodes is less than the expected number.
The programming example below illustrates a TSP-Link reset operation and displays its state:
tsplink.reset()
print(tsplink.state)
If the reset is successful, online will be returned to indicate that communications with all nodes have
been established.

Introduction to TSP advanced features

You can use TSP to run test scripts in parallel on multiple nodes on the TSP-Link network.
You can also use TSP to manage resources allocated to test scripts running in parallel, and to use
the data queue to facilitate real-time communication between nodes.
Running test scripts in parallel improves functional testing, provides higher throughput, and expands
system flexibility.
There are two methods you can use to run test scripts in parallel:
•
Create multiple TSP-Link networks
•
Use a single TSP-Link network with groups
The following table describes the functions of a single TSP-Link network. Each group in this example
runs multiple test scripts at the same time or in parallel.

Description
Initializes the TSP-Link network.
Returns "online" if the most recent TSP-Link reset was
successful. Returns "offline" if the reset operation failed.
