Figure 30- Keypad and LEDs
Functions of the Keypad
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:
¾Login the administrator
¾Logout the administrator
¾Disconnect the administrator or a user with administrative privileges
¾Login a user to the administrator main menu
¾Login a user to a port
¾Login a user and connect the user to a host port
¾Disconnect and logout a user
¾Connect 2 host ports
¾Disconnect 2 ports
¾Connect or disconnect a modem
To enable the keypad, 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.

–the specified port is not otherwise already connected and the port type is “User”.
Note: If wrong digits are pressed when entering port numbers, enter the number for the correct port (01, 02, etc) before pressing the “Enter” key. The Console Switch will acknowledge the last two digits pressed.
