To assign a node number using a remote command:
Set the
tsplink.node
attribute of the instrument:
tsplink.node =
N
Where
:
N
= 1 to 64
To determine the node number of an instrument, you can read the
tsplink.node
attribute by
sending the following command:
print(tsplink.node)
The above
command outputs the node number. For example, if the node number is 1, the
value
1.00
is displayed.
Resetting the TSP-Link network
After all the node numbers are set, you must initialize the system by performing a TSP-Link
®
network
reset.
If you change the system configuration after initialization, you must reinitialize the system by
performing a TSP-Link network reset. Changes that require that you reinitialize the TSP-Link network
include turning off power or rebooting any instrument in the system, or rearranging or disconnecting
the TSP-Link cable connections between instruments.
