6.1.6 Edan Transducer Socket Board (wired model only)

The EDAN transducer socket board locates on the left of the lower case, i.e. the left of the
monitor. It communicates between the main control board and external transducer accessories. Its
function is to isolate the signal of accessories, power supply and ground, and transfers collected
SpO2 and TEMP signals to iM X12 parameter board.
