Dynament premier methane sensor interface with arduino

I am trying to interface premier methane sensor from Dynament with arduino board.
baud rate used.9600
when command is issued through Arduino the response is invalid in case 1,2.
else when the command send directly response is valid if either read directly or through arduino case 3,4.
Is there some thing that I have to include while interfacing this module with arduino.

below is the process I followed.

case 1:

when the command to read the live data from the sensor is triggered from the arduino the response have error in the status flags included in it.
Response read using arduino itself.

case 2:

when the command to read the live data is triggered from the arduino the response have error in the status flags included in it.
Response read directly to PC.

CASE 1,2 output:
command :{10}{13}{01}{10}{1F}{00}{53}

resopnse:{10}{1A}{20}{01}{00}

{40}{00}-status flag

{00}{00}{7A}{C3}{00}{00}{5E}{42}{C4}{03}{84}{02}{C0}{57}{05}{3C}{1B}{90}{02}{00}{00}{00}{00}{00}{00}{00}{00}{00}{10}{1F}{05}{E9}

case 3:
the same command when issued through PC and the response received directly to PC. the output parameters and status flags are correct.

case 4:

the same command when issued through PC and the response received through arduino. the output parameters and status flags are correct.

case 3,4 output:

command:{10}{13}{01}{10}{1F}{00}{53}

response:{10}{1A}{20}{01}{00}
{00}{00}-STATUS FLAGS
{CD}{4C}{E5}{C4}{33}{33}{E3}{41}{42}{04}{FB}{02}{90}{00}{4A}{3D}{DB}{24}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{10}{1F}{08}{1F}
