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-X commands 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-X followed 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.
