Resetting to Factory Default Values
All user options for the H2TU-C-388 List 1 ( Table 5 on page 17 ) can be set to the factory default values using the
MODE and SEL buttons. To set the user options to their default values:
1 Press the SEL button for 6 seconds until the following message appears:
DFLT NO
2 Press the SEL button while the DFLT NO message appears.
The message changes to DFLT YES indicating the factory default values are now in effect and the display
returns to the normal mode.
To terminate the DFLT mode without setting the factory default values, do one of the following:
• Press the MODE button to return to the normal display mode.
• Wait 30 seconds for the unit to return to the normal display mode.

Connecting to a Maintenance Terminal
A miniature, 3-pin, 210 Bantam-type jack on the front panel serves as a craft port and allows connection between
the HiGain Line Unit and a maintenance terminal (ASCII terminal or PC running a terminal emulation program).
A 210-to-DB-9 adapter is provided with every unit to facilitate the use of standard RS-232, DB-9 cables (see
Figure 29 on page 51 ). 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 H2TU-C-388 front panel.
2 Connect an RS-232 cable to the adapter.
3 Connect the other end of the cable to the serial port on the maintenance terminal.
4 Start a terminal emulation program such as ProComm (emulating a VT100 terminal).
