-------------------------------------
After FEC is turned off, the
actual data transmission rate
will be increased, but the
anti-interference ability will be
weakened and the distance
will be slightly closer. Please
select according to the actual
application.
Both sides of the
communication must be on or
off.
-------------------------------------
External power supply must
provide more than 500mA
current output capacity. And
ensure that the power ripple is
less than 100mV.
It is not recommended to use a
small power transmission; its
power utilization efficiency is
not high.
