A miniature, 3-pin, 210 Bantam-type jack on the front panel serves as an RS-232 Craft port and allows connection
between the HLU-388 and a maintenance terminal (ASCII terminal or PC running a terminal emulation program).
The Craft port is configured as Data Communications Equipment (DCE). A 210 to DB-9 adapter is provided with
every unit to facilitate the use of standard RS-232, DB-9 cables. See (
). Once connected to a maintenance
terminal, you can access the maintenance, provisioning, and performance screens.
To connect to a maintenance terminal:
1
Insert the 210-to-DB9 adapter into the RS-232 jack on HLU-388 front panel.
2
Connect an RS-232 cable to the adapter.
3
Connect the other end of the cable to the console port on the maintenance terminal.
4
If necessary, start a terminal emulation program.
5
Configure the maintenance terminal to the following communication settings:
•
1200 to 9600 baud (9600 baud is recommended)
•
no parity
•
8 data bits
•
1 stop bit
•
hardware flow control to OFF
The line code parameter is the actual DSX-1 line code being received by the HLU if the DSX-1
code pattern is set to AUTO. Otherwise, the line code parameter mimics either of the other two
line code settings, AMI or B8ZS.
