Initialization
Set User Passcode
The TDU 120e is designed to operate with or without the use
of a passcode. The default condition is without a passcode.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation
other than viewing. See Set Passcode on page 6-3 for details.
Set Unit Identification
The Unit ID sets the unit to respond to remote control
(controlled by a device other than the front panel or
terminal). If no Unit ID is recorded, it is not possible to
operate from any remote control device, including the local
PC for T-Watch PRO or SNMP. See Unit ID on page 6-3 for
details.
Set Control Port
The TDU 120e can be configured from the control port when
T-Watch PRO, SNMP, or the terminal interface are being
used. If the control port is to be used, the control port baud
rate must also be selected.
Chain In (PC)
The unit can be controlled from an external PC connected
directly or via modem to the Chain-In port. When using
Chain-In, the selection of the Control Port baud rate from
9600 (factory default), 1200, 2400, or 4800, 19200, or 38400
must be made using the U

menu. See Unit
Menu on page 5-8 for details.
If the unit is to be remotely accessed using T-Watch PRO, you
must enter a passcode. When managing a number of units, the
passcode can be the same for all the units.
