Section 6: Instrument programming
Assigning node numbers
At the factory, each Models 707B and 708B 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. You
can assign a node number (1 to 64) to a Models 707B and 708B using the front panel or through
programming.
To assign a node number from the front panel of the instrument:
1. Press the Menu key, then select TSPLINK > NODE.
2. Press the navigation wheel and select the desired number.
3. Press the ENTER key to select the node number.
To assign a node number through programming:
Set the tsplink.node attribute of that 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 displayed.
Remote programming
The tsplink.node attribute is used to set the node number for an instrument:
tsplink.node = N
Where:
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 displayed.
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.
If you change the system topology after initialization, you must reinitialize 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.
