Go to:
The “Recall” function allows you to open positioner positions that were previously stored using the “Save” function. The
positioner then turns to the saved position. Position 0 corresponds to the reference position of 0 degrees. The last posi-
tion accessed is displayed in the LNB window after “P”, e.g. “P03”. This position is incorporated into the tuning memory.
As a result, various orbital positions can conveniently be recalled from the tuning memory. There is no need do so indi-
rectly via the
Positioner

6.5.2.4 DiSEqC V2.0 control
LNB
> DiSEqC > V2.0 activates the DiSEqC control V2.0. The difference from V1.0 is the additional feedback query of a
controlled DiSEqC component. When the device controls a multiswitch with DiSEqC V2.0, it sends an answer back to
the device.
The device evaluates this feedback and reports “
DiSEqC reply correctly received
” if successful, or “
DiSEqC reply
incorrectly received
” if there is an error. If the reception of the reply is correct, but the contents is not 0xE4 (reception
ok), the reply ’DiSEqC reply = 0x…‘ (including the HEX-Code) is shown in a blue window.
6.5.3 UNICABLE
The UNICABLE version (satellite signal distribution over a single coaxial cable distribution network) is a variant of the
DiSEqC control and corresponds to DIN EN 50494. With this system, the desired transponder is converted to a fixed
frequency (centre frequency of the UB slot or bandpass) in the UNICABLE unit (LNB or multiswitch). The information
coordinating transponders and UB slots is transmitted via the special DiSEqC command to the UNICABLE unit. The
standard supports up to 8 UB slots. This allows up to 8 receivers to be operated on 1 cable.
The UNICABLE message contains the following information:
SCR address, horizontal and vertical polarisation, low or high band, and the transponder frequency to be set.
The following control routine is used in this device:
With UNICABLE systems, the signal-generating receiver generates a high DC level as it transmits, which is added to the
UNICABLE message (special DiSEqC command). After transmitting the UNICABLE message, the receiver returns to an
idle state, in which a low DC level is generated. The receiver must return to a low DC level so that the system is available
for other receivers.
The measuring receiver uses 14 V for the low DC level and 18 V for the high DC level.
6.5.3.1 Activation and Configuration
The UNICABLE control is activated via
LNB
> DiSEqC > UNIC.
The first menu that appears allows users to choose between setting the SCR-ADR-BANK and setting the SCR-ADR
(satellite channel router address). In the SCR-ADR menu, users can select the user band (UB) bandpass slot for the
measuring receiver to use and edit the corresponding centre frequency. These parameters can be obtained from the
data sheet of the UNICABLE unit being used.
