9-2 System Expansion (TSP-Link) Series 2600 System SourceMeters Reference Manual
2600S-901-01 Rev. A / May 2006 Return to Section 9 topics
Overview
The TSP-Link is an expansion interface that allows the instruments to
communicate with each other. The test system can be expanded to include up to
64 TSP-Link-enabled instruments.
Master and Slaves
In a TSP-Link system, one of the nodes (instruments) is the Master and the other
nodes are the Slaves.
The Master can control the other nodes (Slaves) in the system. When any node
transitions from local operation to remote, it becomes the Master of the system; all
other nodes also transition to remote operation, and become its Slaves. When
any node transitions from remote operation to local, all other nodes also transition
to local operation, and the Master/Slave relationship between nodes is dissolved.
For more information about remote and local operations, see “
Differences: remote
vs. local state” in Section 2.
A Slave is a node that is controlled by the Master. The GPIB and RS-232
command interfaces of the Slaves are disabled.
System configurations
A TSP-Link system can be used without a PC (stand-alone system) or as a
PC-based system.
Stand-alone system – In a stand-alone system, scripts that control the system
are executed from the front panel of one of the instruments. No PC connection is
required. In
Figure 9-1, a script can be run from the front panel of any one of the
instruments.
PC-based system – In a PC-based system, the GPIB or RS-232 interface to any
single node becomes the interface to the entire system. In
Figure 9-1, the system
can be controlled via the GPIB or RS-232 interface of Node 1.
