To set up communication to a remote ethernet-enabled device that is not TSP enabled:
Send the command:
connectionID = tspnet.connect(ipAddress, portNumber, initString)
Where:
â–ª connectionID is the connection ID that will be used as a handle in all other tspnet function calls.
â–ª ipAddress is the IP address, entered as a string, of the remote device.
â–ª portNumber is the port number of the remote device.
â–ª initString is the initialization string that is to be sent to ipAddress.
See tspnet.connect() (on page 11-434) for additional detail.
To communicate to a remote ethernet device from the Series 3700A:
1. Connect to the remote device using one of the above procedures. If the Series 3700A cannot
make a connection to the remote device, it generates a timeout event. Use tspnet.timeout to
set the timeout value. The default timeout value is 20 s.
2. Use tspnet.write() or tspnet.execute() to send strings to a remote device. If you use:
â–ª tspnet.write(): Strings are sent to the device exactly as indicated, and you must supply
any needed termination characters.
â–ª tspnet.execute(): The Series 3700A appends termination characters to all strings that
are sent. Use tspnet.termination() to specify the termination character.
3. To retrieve responses from the remote instrument, use tspnet.read(). The Series 3700A
suspends operation until the remote device responds or a timeout event is generated. To check if
data is available from the remote instrument, use tspnet.readavailable().
4. Disconnect from the remote device using the tspnet.disconnect() function. Terminate all
remote connections using tspnet.reset().
