5.3. Parameters saving
Once a parameter is modifi ed to the desired value
in any menu (normal or extended), to save the
settings press for three seconds. The display will
show the following indication:
Saving
settings and
restarting
...
Do not remove the controller until the message
disappears.
If the confi guration parameters are modifi ed but
not saved, the previous confi guration is retrieved
after 30 sec. in other words, the changes are
discarded.
Finally, the LEDS indicate the following operating
conditions:
- Left LED (A) = The level of the input signal is
suffi cient (for guidance).
- Central LED (B) = Hooking of the COFDM
demodulator.
- Right LED (C) = Hooking of the COFDM modulator
/ Right adjustment.
LEDs ON, indicate correct operation.
If any of them turns OFF is a sign of anomalous
behavior.
The LED on the front of the unit indicates whether
the COFDM demodulator is hooked: it glows green
when hooked, and glows red when not.
6. - Controlling the Device
This version of the COFDM-COFDM CI allows
confi guration and monitoring via a PC, both locally
and remotely.
a. Local control
The “Headend Management” programme (v2.14
or higher) is required, as well as a special cable
(provided with the programme) that connects a
PC serial port to the COFDM-COFDM CI “PRGM”
connector.
The programme can be used to set up and read all
the operating parameters, as well as to monitor the
correct operation of the device.
b. Remote control
It is necessary to have a Headend Control module
(ref. 5559 or 555901) that includes the programme
mentioned above.
Once the communication with the headend
control has been established, all the controllable
devices that have been installed in the headend
can be accessed. In this case it is essential that each
element be programmed with a diff erent device
address between 1 and 254.
