   The Advanced Engine Management (AEM) 4 channel thermocouple amplifier revolutionizes 
temperature measurements by providing labora tory grade accuracy for your temperature 
measurements. The accuracy is guaranteed to be be tter than 1% full scale, even at the extremes 
of the temperature range. It is designed either  for integration into vehicles already fitted with 
aftermarket ECU’s or other devices that can accept an analog signal for either analysis or 
logging. Alternately, an RS-232 output is...

voltage given by a thermocouple with a multi-meter. This is because the thermocouple acts as a 
differential device between the junctions and the connection of a multi-meter creates a junction 
at that point as well. The voltage supplied is for the difference of the temperature at the two 
different ends of the thermocouple so the output voltage will be for the temperature difference 
between the two points, not the absolute temp erature at the measurement tip. This makes 
knowing the temperature at the...

 
SERIAL OUTPUT 
   The serial output can be used for data logging when an EFI system is not accessible. To run the 
data stream, a RS-232 (DB-9) Fema le Receptacle must be purchased.

Wire View of RS-232 (DB-9) Male Plug 
 
   Two wires need to be connected to a RS- 232 serial port. The YELLOW wire from the AEM 
thermocouple amplifier shall be connected to Pin  #2 (RX) on the serial port for receiving data. 
Pin # 5 (GND) on the serial port  is the ground and should be conne cted to the...
