Chapter 4. Console Port Operation
53
May 2011
Use the ESC key to return to the top Setup menu. Select item "4" Password.
The menu contains only two password items, setting the password or clearing the password.
The password must consist of four numbers; therefore the range of passwords is from 0000 to 9999.
To clear the password, you must enter the original password once. If you forget the password, you
will not be able to gain access to the menu items "Define System Parameter" or "Test Function
Parameter". You may only access the "Display System Status" and "Password" items. There is a
backdoor password but it is not contained in this document. You must contact our representative or
our support department and request the backdoor password.
Again, from the main Setup menu, the item "5", Reset Data to Default will clear all settings in
the ETU-01A back to factory default. This may be necessary when changing operational firmware
chip or if the unit exhibits strange behavior while configuring. In such cases, we recommend doing
the factory reset and reconfiguring the unit as a last effort before returning a unit for factory repair.
Pressing Enter again on the above screen will reset the ETU-01A to factory default. The
default settings are as follows:
Master Timing = Recovery
Framing = CCS (PCM31)
CRC4 = On
Line Code = HDB3
RAI = Enabled
Idle Code = 7F
E-bit = Off
Cascade = Off
Timeslot Assignment = TS01~31 (31x64kbps or 1984kbps)
