Using TSP-NetTM vs. TSP-LinkTM for communication
with TSP-enabled devices
TSP-Link is the preferred communication method when communicating between
the Series 3700 and another TSP
TM
-enabled instrument. Using TSP-Link has
certain advantages over using TSP-Net, including:
Error checking: When connected to a TSP-enabled device, all errors that
occur on the remote device are transferred to the error queue of the Series
3700. The Series 3700 indicates errors from the remote device by prefacing
these errors with “Remote Error”.
For example, if the remote device generates error number 4909, the Series
3700 generates the error string “Remote Error: (4909) Reading buffer not
found within device.”
Digital I/O Triggering: TSP-Link connections have three TSP
synchronization lines that are available to each device on the TSP-Link
network. You can use any one of the TSP synchronization lines to perform
hardware triggering between devices on the TSP-Link network. Refer to
Hardware trigger modes (on page 8-18) for more details.
These advantages make using TSP-Link to control another TSP-enabled device
the best choice for most applications. However, if the distance between the
Series 3700 and the TSP-enabled device is longer than 15 feet, use TSP-Net.
To establish a remote TSP-Net connection with a TSP-enabled device, use
tsp.connect() without specifying a port number. The Series 3700 enables
TSP prompt and error handling for the remote device, which allows you to
successfully use the tspnet.tsp set of commands to load and run scripts and
retrieve reading buffers.
Abort any operation on the remote TSP-enabled device using abort().
