HCD-E1 Installation & Operation Manual Chapter 3 - Front Panel Operating Instructions
11/01/00 19:52 Local Configuration Setup Procedure 3-23
Password
Protection
HCD-E1 has password protection designed to avoid undesirable
modification of its parameters. You will be able to configure HCD-E1 from
the front panel only if its password protection is disabled. Otherwise, you
can use the HCD-E1 front panel to display the current parameter values, but
cannot modify them. If you try to modify a parameter or perform a test
function from the front panel while the password protection is enabled,
HCD-E1 will display CONFIG ERROR 04 (for the list of configuration error
messages see Table 5-5 in Chapter 5).
If you have access to an ASCII control terminal, you can use the DEF SP
command to enable or disable the password protection (see Chapter 4 for
detailed instructions).
If the terminal is not available, you must set for a short time the DB INIT
section of the internal switch S1 to ON for disabling password protection, as
explained in Section 2-4.
Note
This action will delete all the current parameters on your HCD-E1 and make
it use the default parameter values. If your unit is configured as central, these
parameters will be also automatically downloaded to the remote unit. That is
to say, now you will need to reconfigure both the central and the remote
unit. The only case you would not have to do it is when your unit is
configured as remote and you want its parameters to be automatically
downloaded from the unit configured as central (its CONFIG REM parameter
from SYSTEM PARAMETER menu set at YES).
General
Configuration
Procedure
Before starting the configuration procedure, make sure that all the
user-initiated loopbacks are disconnected. To disconnect the loopbacks,
select OFF under the TEST OPTION field (see Section 5.4, Diagnostic Tests,
in Chapter 5).
If your configuration attempt is invalid, HCD-E1 shortly displays a CONFIG
ERROR XY message (the code XY identifying the error) and then returns to
its normal display. For explanation of the configuration error messages refer
to Section 5.5, Configuration Error Messages, in Chapter 5.
