The 9-pin, RS-232 Craft port on the front panel allows you to connect the HLU-231 to a maintenance terminal
(ASCII terminal or PC running a terminal emulation program). Once connected to a maintenance terminal, you
can access the maintenance, provisioning, and performance screens.
To connect to a maintenance terminal:
1
Connect a standard 9-pin terminal cable to the RS-232 Craft port on the HLU-231 front panel.
2
Connect the other end of the console cable to the console port on the maintenance terminal.
3
If necessary, start a terminal emulation program.
4
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
A standard RS-232 (DB-9, female) connector on the front panel provides access to the screen interface feature
through a maintenance terminal (
).
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.
