The string shows the overall level of the signal from LNB. It reports the current RF level, as well as maximum and

minimum peaks registered during the pointing assistance. Further, the demodulator state status: percentage of

search circle when demodulator is unlocked.

or “Locked” me- or the percentage of scanned strip search in the current cycle, or a message that the

demodulator is found and adopted a signal.

When demodulator is locked on the carrier its “Status” change to “Locked and further three values represent- the

C/N levels of demodulator (current, maximum and minimum).

Type “Q” to exit pointing assistance mode.

2.14.3 Pointing with analog reference signal

The router may output an analog signal via USB port equivalent to quality of reception of the demodulator. This

voltage can be used for pointing the antenna to the satellite during installation or/and as a reference signal form

automatic antenna tracking system.

Figure 24 Pinout of USB Console interface

The analog pointing signal is available on the Pin 1 of USB “Console” port (to be used with “Ground” signal on the

Pin 4). In the standard mode the pin 1 used to deliver a 5 VDC power from the computer. When pointing feature is

activated the pin 1 represents output voltage ranging from 0 to 3.3 volts. Such voltage does not interfere with

standard USB port operations. Short-circuiting this signal to Ground is not critical, however input voltage above 5

VDC is not allowed.

Standard (analog or digital) voltmeter connected to this signal could be used as a reference toll for antenna

pointing. Installer may use Tx coax cable to deliver such signal from the router (indoor) to antenna (outdoor) – this

cable is not used while antenna pointing. Special adapters to connect the F-connector of coaxial cable to USB

output and a voltmeter can be purchased from your local distributor or make by your own.

When this mode is active the voltage is changed within the following range:

 When demodulator the voltage is in-between 0 and 1 Volt proportionally to the overall Rx level of the

demodulator;

 When demodulator is locked the voltage is proportional to C/N and ranging from 1 V to 3.3 V. Voltage

above 1V is proportional to C/N with ration 10dB/1V, e.g. reception of the carrier with C/N signal of 5 dB

will be represented as 1.5 V signal on USB port, 10 dB - 2V, etc.

The pointing mode is activated by the following command::

demodulator antenna [0-800] [0-800] - Antenna pointing mode [RF min] [RF max]

Two optional command parameters - the range of IF levels corresponding to the voltage range 0-1V. If omitted, the

current level is taken as the minimum, and level 15dB higher than actual is taken as a maximum.

When activating the pointing mode while antenna is already pointed to the satellite the default minimum level

may be set too high. It is not a problem if the intention is just fine pointing of antenna to the same satellite.

However this may create a problem re-pointing the antenna to another satellite, because the reference level may

not react on lower signals when antenna is disoriented from the initial satellite. To prevent this, it’s recommended

to define the desired range manually.
