Abstract

PURPOSE: To facilitate an easy detection of the circuit function and the transmission circuit by providing the circuit function detector circuit which light up all lamps when no fault is detected.
CONSTITUTION: Data transmission connector 2 is connected previously to transmission circuit detecting connector 12. And the normal and abnormal states are checked via transmission error lamp 8, time-over lamp 9, reception lamp 10 and transmission lamp 11 each for the transmission error detection, time-over detection, transmission/reception circuit functions and the transmission circuit respectively through operation of power switch 3, transmission-reception change-over switch 4 plus circuit function and transmission circuit detecting switch 5 and 6 respectively. When no fault is detected with the circuit function, lamps 8W11 are all lit up. Thus, the lamp does not light up if the lamp itself has some fault. In other words, not only the circuit function but also the lamp quality can be checked at one time.
