When the module is in Mode 3 (M0=1 M1=1 M2=0) or Mode 5 (M0=1 M1=0 M2=1), the parameter can be set by
instruction or software in PC. Please visit www.cdebyte.com to download the software.

the power consumption.
For mode 4, the wake-up time decides the
number
of
transmission so as to ensure the wake up
the module in mode 6.
Generally, mode 4 and 6 shall be used
jointly and the wake-up time on both
modules shall be the same.
After turn off FEC, the actual data
transmission
anti-interference ability decreases. Also,
the transmission distance is relatively
short.
Both communication parties must keep on
the same pages about turn-on or turn-off
FEC.
This bit is used to the internal pull-up
resistor. It also increases the level's
adaptability in case of open drain. But in
some cases, it may need external pull-up
resistor.
The external power must ensure that the
ability of current output is more than 80mA
and the power supply ripple is within
100mV.
Low
power
recommended due to its low power supply
efficiency.
