If no other means are available to access NetClock, a terminal emulation program can be used to carry out certain configuration changes by accessing NetClock's CLI (command-line interface) via a serial port connection. An application example for this scenario is to enable a network port so that the NetClock Web UI can be used. While it is also possible to retrieve selected logs, a terminal emulator does not replace the NetClock Web UI.
Spectracom does not distribute or support its own terminal emulator, and newer Microsoft operating systems no longer include HyperTerminal. However, there are several third-party open-source programs available, such as TeraTerm® or PuTTY®. The example below illustrates the use of TeraTerm. The setup procedure is similar when using other terminal emulation programs.
Required tools and parts:
- A standard, one-to-one pinned RS-232 serial cable; this cable has one male and one female DB-9 connector. Do NOT use a Null Modem cable. If you do not have a standard RS-232 cable at hand, follow the pin-out configuration described below when building a cable. It is required to wire at least pins number 2, 3, and 5.
- Personal Computer with terminal emulator program installed.
Serial port pin-out
- Connect the personal computer to the
front panel serial connectorUSB interface , using the serial cable.
- Configure your terminal emulation program, using the following settings:
- Port: COM1
- Bits per second: 9600
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
- Depending on which network protocol you are using (SSH, Telnet), you will need to enter authentication upon establishment of the connection either in a separate authentication window, or the Terminal window: The default user name is
spadmin, and the password
- Using the Terminal window, you can now submit commands
; see CLI Commands for a list of commands.
