Series 2600A System SourceMeter® Instruments Reference Manual Section 14: System Expansion (TSP-Link)

Initialization

Before a TSP-Link system can be used, it must be initialized. For initialization to succeed, each

instrument in a TSP-Link system must be assigned a different node number.

Assigning node numbers

At the factory, each Series 2600A instrument is assigned as Node 1. The node number for each

unit is stored in its nonvolatile memory and will not be lost when the instrument is turned off.

Front panel operation

You can use the front panel of a instrument to assign a node number to that instrument (node). You

can assign any number from 1 to 64 to the node.

Complete the following steps to assign a node number from the front panel of the instrument.

1. Press Menu > TSPLINK > NODE.

2. Press the navigation wheel and select the desired number.

3. Press ENTER to select the node number.

Remote programming

The tsplink.node attribute is used to set the node number for an instrument:

tsplink.node = N

Where: N = 1 to 64

The node number of an instrument can be determined by reading the tsplink.node attribute as

follows:

print(tsplink.node)

The above print command will output the node number. For example, if the node number is 1, the

value

1.000000e+00 will be output.

Resetting the TSP-Link

After all the node numbers are set, you must initialize the system by performing a TSP-Link reset.

For initialization to succeed, all units must be powered on when the TSP-Link reset is performed.

NOTE If you change the system topology after initialization, you must

re-initialize the system by performing a TSP-Link reset. Changes that

affect the system topology include powering down or rebooting any

unit in the system, or rearranging or disconnecting the LAN cable

connections between units.

Front panel operation

Complete the following steps to reset the TSP-Link network from the front panel.

1. Press Menu > TSPLINK.

2. Press RESET.
