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.
5 - Unit is in Backup state of Redundancy mode. Not an error.
Continuous signal means that the router has hardware or configuration errors. If ERROR indicator is continuously
lit upon power on it means hardware failure of UHP occurred which prevents software from starting. Try to power
it off and power on again or press RESET button on rear panel.
1.5.12 “LOCK” Indicator
“LOCK” indicator indicates whether the router receives a channel from the Hub or other station. If there are CRC
errors during reception of information from the channel (e.g. with weak signal from the antenna), the indicator
extinguishes for a fraction of a second at every error. If there are too many errors the indicator may not glow at all
in spite of the fact that the router receives the channel (in this case please check the router demodulator
statistics).
1.5.13 “RX1” Indicator
“RX1” indicator flashes every time a data placket is received via RX1 interface.
1.5.14 “RX2” Indicator
“RX2” indicator flashes every time a data placket is received via RX2 interface.
1.5.15 “TX” Indicator
“TX” indicator flashes every time a data placket is transmitted in the MCPC mode, and also a blank packet – in the
TDMA mode (if no data is available for transmission).
