Description Values Default
-
- NomPwr1
NomPwr2 Nominal Rx1 or Rx2 optical input
power level. Input power alarms
are calculated relative to this value.
Decimal number
between -18.0 and
2 dBm in
increments of
0.5 dBm
0 dBm
Mode Select Mode Module redundancy control. If set
to Master, the unit is only
controlled by the Enable control. If
set to Slave, the unit is controlled by
the Enable control and the external
input CNT_IN.
If set to Single, Rx1 and Rx2 will
continue to operate (i.e. not switch)
even if the optical input level falls
below the major alarm threshold.
If set to Independent, Rx1 and Rx2
are independently set to Master or
Slave mode by Mode1 and Mode2.
