2.4 COMMAND LINE INTERFACE
The Command Line Interface (CLI) is a useful tool for checking link status and debugging link
connections. To enable the use of CLI the OSD2254EP must be connected to a PC with a
serial port and an appropriate cable as specified in section 2.2.6. Using a terminal emulation
program such as Hyperterminal, a number of command lines specific to the OSD2254EP can
be implemented to check link/node status, ring/bus topology and enable/disable float backup.
2.4.1 TERMINAL EMULATION SETUP
Using a terminal emulation program such as hyperterminal the following parameters should
be set up for correct command line operation. Select the appropriate “COM port” set up for
the serial port.
