YY Hex number whose value should always be 0x1B in normal operation. If the
value read on the MO-180 display differed from 0x1B this would indicate some
failure in one or more of the circuits that are used to implement the modulation
process. In such a case, please contact a Promax Customer Service Centre.

HP TS buffer full.
In master mode these bits are asserted when
the input HP TS bit rate is greater than the
1
useful bit rate for the DVB-T/H mode in use.
ACTION: Reduce the peak or average bit rate
to avoid overflow.
LP TS buffer full.
1 Same as right above but for the LP TS.
ACTION: See above.
HP TS sync loss.
In master mode when this bit is 1, a loss of
synchronisation with the HP transport stream
1 has occurred (2 or more corrupted or missing
TS SYNC bytes).
ACTION:
compliance of the TS input.
LP TS sync loss.
1
Same as right above but for the LP TS.
ACTION: See above.
TS sync loss.
In MFN slave mode an assertion of this bit
indicates a loss of synchronisation with the
1 input transport stream (2 or more corrupted or
missing TS SYNC byte).
ACTION:
compliance of the TS input.
Valid TS rate.
In MFN slave mode this bit should be 1 in
normal operation. When it is 0 it tells us that
the packet rate of the input transport stream is
not within approximately 100ppm of the useful
0 bit rate for the DVB-T/H parameters currently
being used and thus the modulator is
incapable of acquiring lock.
ACTION: Check that the input bit rate is within
±0.1‰ of the nominal value given in the DVB-
T/H specification.
