Terminal Interface

LOG IN/LOG OFF

Each DL3800E unit is equipped with an integrated RS-232 ASCII user interface that can be accessed through the COMM PORT (DE-9 connector) located on the rear panel of the DL3800E. Through this interface, you can perform various functions described in this section.

When operating in multidrop mode (that is, when multiple DL3800E units may be daisy-chained together for centralized network management), you must log in to establish communication with a single unit on the network. Only one unit may be accessed at a time. All units continuously monitor the line, but only the unit which is logged on will respond to terminal commands. When no unit is logged on, the characters typed on the terminal will not show up on the display screen.

To log on and log off a particular unit, follow these procedures:

1.Type five Ctrl-Xcommands in a row to return a “roll call” of all Node Numbers on the chain.

This feature is useful when the Node Numbers of any units on the network are unknown.

2.Type Ctrl-Xfollowed by #, the node number, and press Enter (or

Return).

These characters will not be displayed on the terminal screen, but the units will receive them.

If passwords are enabled for the unit, you will be prompted for the username and password. Initially, no password or username is needed, so simply press Enter when prompted for a username or password.

3.The Main Menu will appear. If not, check that the Node Number matches what is typed on the terminal.

If it still does not appear, check that the DL3800E unit port settings match the terminal settings (baud rate, parity, data bits, and stop bits). If so, a null modem adapter may be required to interchange pins 2 and 3 (transmit and receive) from the terminal.
