5 Troubleshooting
5.1 TS Input (Exciter Mode)
TS1 ERROR
Alarm message
LCD:
TS1 ERR
LED_ TS1:
Off
LED_ TSErr: On
Dry Loop:
0 V (TS Fault)
Cause: Input signal from port [TS_IN_1] is lost or has invalid format.
Solution: Check connection of port [TS_IN_1], and make sure input signal has valid format.
TS2 ERROR
Alarm message
LCD:
TS2 ERROR
LED_ TS2:
Off
LED_ TSErr: On
Dry Loop:
0 V (TS Fault)
Cause: Input signal from port [TS_IN_2] is lost or has invalid format.
Solution: Check connection of port [TS_IN_2], and make sure input signal has valid format.
Transport Stream Rate Overflow or Underflow
Alarm message
LCD:
TS_RATE Overflow
Cause: The input TS bit rate is higher than the bit rate required.
Solution: Adjust the TS input bit rate. Or connect all devices with the same reference clock
(GPS).
Note:
When in Exciter Mode, it has bit rate auto-adaptation function to deal with the bit rate mismatch.
It will automatically delete null packets or insert null packets when necessary to achieve the
accurate acquired bit rate. The function is able to be turned off in advanced settings.
5.2 Tuner Input (Translator Mode)
Synchronization error
Alarm message
LCD:
None
LED_ TS1:
Off
LED_ TSErr:
Flashing
Dry Loop:
0 V (SysErr Fault)
Cause: The input RF signal from port [TUNER_IN] will first go through the synchronization and
could not pass this step probably due to a week signal or a wrong received channel setup.
Solution: Make sure the received channel setting (RXFREQ) is correct and the input level of port
[TUNER_IN] is stable and within acceptable range (-80 dBm ~ -15 dBm, with recommended
range -60 dBm ~ -40 dBm).
