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
