For mode 6, the wake-up time will affect the WOR
cycle of the module, and affect the power
consumption.
For mode 4, the wake-up time decides the number
of wake-up code before 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.

FEC switch
After turn off FEC, the actual data transmission
rate increases while 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.

IO drive mode
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.

transmission power (approximation)
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 transmission is not recommended due
to its low power supply efficiency.

8.Parameter Setting
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.
