Control (Local, Remote)
The ATSC TRANSMITTER is fully-controllable locally (by using the display and the
knob) or by remote (by using RS232/RS485 serial ports). With this parameter it is possible
to set local control or remote control. When local control is selected, only reading commands
from remote will be answered, while writing commands will be denied. In this case, changing
of settings is possible only locally. If remote control is selected, it will be possible to read
the status locally (display) and from remote (RS232, RS485), but changing of settings will
be possible only by remote. In this case, many parameters will become as read-only type
on the display.
Serial (RS232, RS485)
The remote control can be performed by using a serial port (RS232 or RS485) or a
parallel port (TELEMEASURES). While TELEMEASURES port is always enabled, only
one of the two serial ports must be enabled at any time, because they are mutually exclusive.
If you don’t use remote control, don’t care about this parameter.
TLM out (Alarm, Squelch)
The meaning of the digital output of TLM port (pins 6 and 7) can be changed by the user
in two different modes: Alarm (useful to interface a custom remote control system) and
Squelch (useful to interface a switchover control system).
Password
In order to prevent an unauthorized user from changing the settings of the machine, it is
possible to lock the control by inserting a 5-digits password. When the control is unlocked,
the word “Unlocked” is written as parameter value. Click on this parameter and set a digit
at a time. After changing the last digit and answering “Yes” to the confirmation question, the
control is locked and the word “Locked” appears (the lock symbol is visible on the status
bar too). Now, the user can’t change any setting by using the knob and display. However,
they can continue monitoring the status of the equipment by browsing the menus. Most of
the parameters become as read-only type. When the control is locked, click on this
parameter to insert the same 5-digits password used to lock. If the password is correct,
the control will be unlocked, otherwise the control remains locked.
Contact the Elettronika Customer Service if you forget the password.
