Edmund Turner Posted May 14, 2021 Report Share Posted May 14, 2021 Hi all, I am installing Bosch NTC dual pressure 261 230 340 sensors to a Link G4+ Fury. I will be wiring 4 of these sensors to AN Temp 1-4 for temp inputs. As I understand AN Temp 1-2 come with internal pull up resistors. However, Aux temp 3-4 doesnt. My question; install all 4 Bosch temp sensors correctly, I will need to install external 1k ohm pull up resistors for AN Temp 3-4 for all temp sensors to read accurately. Is this correct? I scan thru the forums and online help docs but cant seem to confirm this. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted May 14, 2021 Report Share Posted May 14, 2021 An Temp 1,2,3 & 4 all have internal pullup resistors, The difference between An Temp 1&2 vs 3&4 is that 1&2 are configurable so they can be 1kOhm, 10kOhm or no pullup So no you don't have to add any external pullup resistors to use An Temp 1,2,3&4 with standard NTC temperature sensors. The pressure sensors will need to be wired to An Volt inputs Quote Link to comment Share on other sites More sharing options...
