++
  RS485-BL has a Controllable +3V3 output, user can use this output to power external sensor.
  The +3V3 output will be valid for every sampling. RS485-BL will enable +3V3 output before all sampling and disable the +3V3 after all sampling.
++
  The +3V3 output time can be controlled by AT Command.
++**AT+3V3T=1000**
--(% style="color:#037691" %)**AT+3V3T=1000**
--
--
  Means set +3v3 valid time to have 1000ms. So, the real +3v3 output will actually have 1000ms + sampling time for other sensors.
++
  By default, the AT+3V3T=0. This is a special case, means the +3V3 output is always on at any time

  RS485-BL has a Controllable +5V output, user can use this output to power external sensor.
  The +5V output will be valid for every sampling. RS485-BL will enable +5V output before all sampling and disable the +5v after all sampling.

  The 5V output time can be controlled by AT Command.

++
  By default, the AT+5VT=0. If the external sensor which require 5v and require more time to get stable state, user can use this command to increase the power ON duration for this sensor.
