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.

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.
