RS-232C COMMAND

[CMD ID DATA]

1.  The  adjustment  must  be  performed  in  the  circumstance  of

25±5°C  of  temperature  and  65±10%  of  relative  humidity  if
there is no any specifics.

2.  Before  an  W/B  adjustment,  the  module  which  will  be  used

should  be  placed  in  the  circumstance  of  15°C~25°C  for
above 2 hours.

3. If a module was placed in the circumstance of below 15°C,

it  should  be  placed  in  the  circumstance  of  15°C~25°C  for
above  2  hours  or  be  run  for  above  5  minutes  in  an  aging
environment of 60°C.

4.  Before  an  W/B  adjustment,  TV  set  should  be  run  for  5

minutes at least.

(1) Press  “Power  on”  button  of  a  service  R/C.(Baud  rate  :

115200 bps)

(2) Connect RS232-C Signal Cable.
(3) Write Serial number through RS-232C.
(4) Check  the  serial  number  at  the  Diagnostics  of  ‘SETUP’

menu. (Refer to below).

Caution : Don’t download HDMI/RGB EEPROM to write a model

name.  Model  name  dois  unnecessary  because  this
