DATA TRANSMISSION SYSTEM

摘要: PURPOSE:To attain economization by securing data transmission and reception even if a main terminal equipment side has shift in clock phase, then removing two transformers which are necessary phantom feeding without reference to system. CONSTITUTION:In equipmentI, transistors TrQ1 TrQ2 connected series, the is power source while grounded, connection point between Trs Q1 Q2 through high resistance; TR circuit changes state at (m) corresponding on-off states of Q2, signal receiving for detecting voltage, input provided. A II, on other hand, TrQ3 turned off be sent out, stabilized PS supplying connecting with circuit, output TrQ3, PS. Further, equipmentIand II mutually line DL.
