2. FEC switch
0: close the FEC
1: turn on FEC (default)
---------------------------------------------
1, 0 Transmission power (approximate)
00： 20dBm（Default）
01： 17dBm
10： 14dBm
11： 11dBm
-------------------------------------
 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.
