Using the Craft port
The Craft port, a 9-pin RS-232 connector, on the HLU- 431 front panel allows
you to use a standard RS-232 cable to connect your system to a dumb terminal
or PC running a terminal emulation program. Once connected you can access
the maintenance, provisioning, and performance screens.
To provision the HLU- 431 through the Craft port:
1 Configure the dumb terminal to the following communication settings:
• 1200 to 9600 baud (9600 baud is recommended)
• Parity: NONE
• 8 data bits
• 1 stop bit
• Hardware Flow Control set to NONE
• VT Terminal Emulation
2
Use a serial cable to connect the RS-232 COM port on the dumb terminal
to the HLU-
431 front panel Craft port.
If using the Microsoft Windows terminal emulation program,
from the Settings, Terminal Preference menu, deselect
Show Scroll Bars and Use Function, Arrow, and Ctrl Keys for
Windows.
