16#A000
The signal received by channel 0
exceeds the range of inputs which
can be received by the hardware.
(The ERROR LED indicator blinks.)
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 0 exceeds
the range of inputs which can be received by the hardware.
16#A001
The signal received by channel 1
exceeds the range of inputs which
can be received by the hardware.
(The ERROR LED indicator blinks.)
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 1 exceeds
the range of inputs which can be received by the hardware.
16#A002
The signal received by channel 2
exceeds the range of inputs which
can be received by the hardware.
(The ERROR LED indicator blinks.)
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 2 exceeds
the range of inputs which can be received by the hardware.
16#A003
The signal received by channel 3
exceeds the range of inputs which
can be received by the hardware.
(The ERROR LED indicator blinks.)
Check the module parameter in HWCONFIG.
Check whether the signal received by channel 3 exceeds
the range of inputs which can be received by the hardware.
