Section 18: TSP-NetTM Series 2600A System SourceMeter® Instruments Reference Manual
Overview
TSP-Net
TM
allows the Series 2600A to control Ethernet-enabled devices directly through its LAN
port. This enables the Series 2600A to communicate directly with a non-TSP
TM
-enabled device
without the use of a controlling computer.
TSP-Net capabilities
For both TSP
TM
and non-TSP devices, the TSP-Net library permits the Series 2600A to control a
remote device through the LAN port. Using TSP-Net methods, you can transfer string data to and
from a remote device, transfer and format data into Lua variables, and clear input buffers. TSP-Net
is only accessible using ICL commands from a remote command interface and is not available
from the front panel.
You can use TSP-Net to communicate with any Ethernet-enabled device. However, specific TSP-
Net commands exist for TSP-enabled devices to allow for support of features unique to TSP.
These features include script downloads, reading buffer access, wait completion, and handling of
TSP prompts.
Using TSP-Net with TSP-enabled instruments, a Series 2600A can download a script to another
TSP-enabled device and have both devices run scripts independently. The Series 2600A can read
the data from the remote device and either manipulate the data or send the data to a different
remote device on the LAN. You can simultaneously connect to a maximum of 32 devices using
standard TCP/IP networking techniques through the LAN port of the Series 2600A.
Using TSP-Net with any Ethernet-enabled device
NOTE Refer to Section 19 for more details on the commands presented in
this section.
To communicate to a remote Ethernet-enabled device from the Series 2600A, perform the
following steps:
1. Connect to the remote device through the LAN port.
Use an Ethernet crossover cable to connect directly from the Series 2600A to an Ethernet-
enabled device.
Use a straight-through Ethernet cable and a hub to connect the Series 2600A to any other
device on the LAN.
2. Establish a new connection to a remote device at a specific IP address using
tspnet.connect. For non-TSP
TM
-enabled devices, you must also provide the port
number, or the Series 2600A assumes the remote device to be TSP-capable and enables
TSP prompts and error handling.
If the Series 2600A is not able to make a connection to the remote device, it generates a
timeout error. Use
tspnet.timeout to set the timeout value. The default timeout value is
20 seconds.
