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 Eb/No levels of demodulator (current, maximum and minimum).

Type ―Q‖ to exit pointing assistance mode.

2.10.3 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 23 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 Eb/No and ranging from 1

V to 3.3 V. Voltage above 1V is proportional to Eb/No with ration 10dB/1V, e.g.

reception of the carrier with Eb/No 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
