1.2.8 Modulator output (TX OUT)

TX OUT OUTPUT CAN FEATURE 24 VDC WITH A HIGH SHORT-CIRCUIT CURRENT. SHORT CIRCUITING CAN CAUSE

SPARKLE SPREAD AND BURNS. THIS VOLTAGE CAN DAMAGE MEASUREMENT EQUIPMENT IF IT IS NOT PROTECTED AT ITS

INPUTS. SUPPLYING EXTERNAL VOLTAGE TO THIS CONNECTOR IS OBJECTIONABLE AND SUPPLYING MORE THAN 24 V IS

PROHIBITED.

UHP-1000 modulator is compatible with most satellite transmitters/converters (BUC). Those incompatible are only

transmitters that require to explicit “TX On” FSK command but such transmitters are extremely rare and are not

widely employed.

Modulator is connected directly to the transmitter IF connector. Router provides 24 VDC power supply to the

transmitter and 10 MHz reference signal. UHP-1000 is not provided with a separate protection on the transmitter

power supply circuitry. Use is made of current protection for the power supply adapter. In case of a short circuit

the router is de-energized and then gets restarted. If power supply is switched on in the configuration, restarts

continue at 5 seconds interval until short circuiting is removed.

ANY OPERATIONS WITH IF TX CABLE SHOULD BE PERFORMED WITH 24 V SUPPLY VOLTAGE TURNED OFF. OTHERWISE,

SELF-INDUCTION ACROSS A LONG CABLE CAN DAMAGE THE TRANSMITTER AND/OR ROUTER.

1.2.9 “ERROR” Indicator

“ERROR” red indicator makes it possible to infer about problems in the router functioning. The type of the

generated problem can be judged by the number of indicator flashes:

1 – Demodulator cannot receive MCPC channel from the Hub (other Terminal). Please check AGC value in the

demodulator statistics to determine whether there is a signal from antenna (see description of reception

problems) to separate LNB and cable faults.

2 – Router cannot receive TDMA configuration from the HUB (TDM/TDMA network mode). The reason can be in

the non-availability of receive channel from the HUB, CRC errors during reception, wrong configuration of the

Terminal.

3 - Router cannot calculate time shift with respect to the HUB. The reason can be in the non-availability of

reception or a large number of CRC errors during reception.

4 – HUB cannot receive signal from this terminal. Please check transmit signal level of the terminal, whether power

supply and the reference signal for the transmitter are switched on (or off if required), whether DTTS or

geographical coordinates are set correctly in the TDMA settings.

Continuous signal means that the router has hardware or configuration errors, which can be viewed with the

command "show errors" (see paragraph 2.2.10)
