Telnet Interface

Chapter 10. SERIAL INTERFACE OPERATION
Figure 8-2. Telnet Interface Example – Windows Command-line
The SLM-5650A has a Telnet interface for the purpose of equipment M&C via the Serial Remote
Control protocol.
The Telnet interface requires user login at the Administrator and Read/Write user access levels.
Once you log in to the Telnet interface as the Administrator, you have access to the standard
serial-based Remote Control Interface. Figure 8-2 shows an example of the login process using
Windows Command-line.
The Telnet interface is also available for use with the menu-driven CLI that is provided with the
optional NP Interface – but only when the security level setting for the NP Interface has been set
as "Low".
8.3.1

Using HyperTerminal for Telnet Remote Control Operation

There is a disadvantage when using Windows Command line as a Telnet client with the optional
Remote Control protocol. For the messages coming from the Telnet Server, Command line
cannot translate a carriage return command (\r) to a carriage return + line feed command (\r\n).
Therefore, any multi-line Target-to-Controller response (e.g., the response to the RNE? query)
shows as one line, with the latter lines overwriting the previous lines.
To see the full response messages, you can use the HyperTerminal terminal emulation program
configured as a Telnet client. Figure 8-3 shows an example of the login process and remote
control operation when you use HyperTerminal as the interface.
