It's possible to pull the i2c bus and put the mcp9803 temp sensor far away from controller ?(Around 2 meters by using shielded cable)

Thanks.

Hello *

I connect MCP9801 to the PIC and i put the 3 Adressline to VCC (A0,A1,A2)
So i change onliy the 2 Lines of the Programm above:

adr_R con %10011111 ;adr mpc9803 read Adresse 111
adr_W CON %10011110 ;adr mpc9803 write Adresse 111

I get always 16.0 C on the display.

Thank for feedback.
