During normal operation, the current administrator port number (if any) is displayed on the front panel. The corresponding port
LED will be continuously illuminated. The data traffic between connected ports is indicated by the blinking of the corresponding
port LEDs.
Using the keypad, anyone with physical access to the SERIMUX can:
¾ Login the administrator
¾ Logout the administrator
¾ Disconnect the administrator or a user with administrative privileges
¾ Login a user to the administrator main menu
¾ Login a user to a port
¾ Login a user and connect the user to a host port

, the user must first press the “Enter” key on the keypad, enter the PIN on the keypad (default is 9999, see
also page 23) and press the “Enter” key again. The keypad is disabled again after 30 seconds of inactivity. If the keypad PIN is
not entered, the keys will have no effect. If the PIN is successful, the Port, Discon, Admin, and User LEDs will all illuminate and
remain illuminated for up to 30 seconds or until a command is entered.
FYI: Buttons pressed in sequence on the keypad to enter commands must be pressed within 5 seconds of each other
for the SERIMUX to respond. Otherwise, the sequence will need to be repeated from the beginning.
Login the administrator
Note: In order to login the administrator to a port other than port 0, the administrator must first configure the desired
port as a user port (see page 10). By default, all ports, other than 0, are configured as host ports.
