∞ Frequency setup of working channel (1
st
led flashes in red color in case of fine calibration of
parameters)
At this point the DSP reaches its normal running status and the leds behave as follows:
∞ 1
st
upper led: it flashes in green color if calibration of TX failed; it is green during transmission on TS1;
it flashes in red color if multichannel is enabled but the DSP cannot receive data correctly (this
function will be assigned to the 2
nd
led in future SW version); otherwise it is off;
∞ 2
nd
led: it flashes in green color if calibration of RX failed; it is green during transmission on TS2; it
flashes in red color if multichannel is enabled but the DSP cannot receive clock correctly (this function
will be assigned to the 3
rd
led in future SW version); otherwise it is off;
∞ 3
rd
led: it flashes in green color if calibration of TXRX loop failed; it is green during reception from
TS1; otherwise it is off;
∞ 4
th
led: it flashes in green color if the system clock is locked to the synchronism source; it is green
during reception from TS2; it flashes in red color if the DSP is not locked to the synchronism source as
set in “AFC” routine; otherwise it is off;
∞ 5
th
led: it flashes in orange color during data communication through ethernet port; otherwise it is off;
∞ 6
th
led: it is green if the ethernet connection is established; otherwise it is off.
During analog transmission (or reception), both the leds related to transmission (or reception) on TS1 and TS2
are green, because both the timeslot are busy during analog communication.
5.2.3 RX
RX module is equipped with two leds:
∞ the upper led flashes very fast in green-red color during data reception-transmission through control
serial port of the module (during FW upload process on peripheral microprocessor); it is red in case of
unlock of the upper local oscillator which is used to tune the RX; otherwise it is off;
∞ the lower led flashes in red color if there is no application (main) FW uploaded to peripheral
microprocessor; it flashes in green color during start-up booting process; it is red in case of unlock of
at least one of the IF local oscillators; otherwise it is off.
5.2.4 TX
TX module is equipped with two leds:
∞ the upper led flashes very fast in green-red color during data reception-transmission through control
serial port of the module (during FW upload process on peripheral microprocessor); it is red in case of
unlock of the local oscillator or during transmission if the generated RF power is less than a half of its
set value; it is green during transmission with a greater RF power than 10W; otherwise it is off;
∞ the lower led flashes in red color if there is no application (main) FW uploaded to peripheral
microprocessor; it flashes in green color during start-up booting process; it is red in case of excessive
SWR and consequent forced interruption of transmission; it is green during transmission with a lower
(or equal) RF power than 10W; otherwise it is off.
5.2.5 I/O
I/O module is equipped with eight leds, of which the upper 6 reflect the status of corresponding digital I/O
contacts that are present on the back side of the equipment, while the lower 2 reflect the status of the
embedded GSM/GPRS-GPS device. They behave as follows:
