Using the Terminal Interface
To configure the switch, connect a null-modem
cable to the COM port of your PC and to the EIA
232 port of the switch. Use a VT-100 terminal
emulation program to configure your PC COM port
as follows:
v19200 baud
v8 data bits
v1 stop bit
vNo parity
vHardware flow control: Off
vVT-100 emulation
vThe ASCII terminal’s communications port
number that connects the switch
On the Logon panel, enter the user name and
password.
Note: The default Read/Write User Name is: admin
The default password is blank (no password).
On the Main Menu:
vTab and Arrow keys—navigate through the menu
vEnter—selects menu item
vF1 or Help—displays keyboard commands
vF2–toggles between menu text and Command
Bar.
vF3 or PREV MENU—returns to the previous
display
vF4–saves changes.
