E Communicating Through
TCP/IP Over Telnet
The EXFO Instrument Control provides SCPI automation or remote control
over Telnet through TCP/IP as a Windows Service that continuously listens
to a port from a Telnet server (FTB/IQS/LTB) on which modules to be
tested are connected.
There are two types of commands that can be sent over Telnet: SCPI
commands and internal protocol commands of the TCP/IP over Telnet
service. The internal commands allow you to perform certain actions such
as send SCPI commands as a script instead of one by one, force the
disconnection of an active session, view the status of modules and of
connected clients, etc.
Executing SCPI Commands Over Telnet
You can remotely control the modules by executing SCPI commands
through TCP/IP over Telnet. The commands are sent remotely from the
Telnet client (on a computer) to the Telnet server (in this case, the IQS,
FTB, or LTB unit).
You can connect from a remote Windows client or a Linux (or Unix)
remote client.
Note: The Telnet client is available on almost all units in case you intend to use
these units as computers to connect to a Telnet server. However, on an
FTB-1v2, FTB-2, or LTB-1 running Windows Embedded 8 Standard, the
Telnet client is not available. With these units, you must use the PuTTY
application to establish communication.
Before being able to send SCPI commands, you must first establish a
connection to the Telnet service.
