Emitter Emitter of LED-transistor optocoupler. Notifies host com-
puter of absence of a-c input or a major power supply fail-
ure, active “low” (see PAR 1.4.10), requires pin 7 to be
connected to the “+“ of the host computer d-c supply as
described in PAR. 2.9.
5 Not Used.
6 Not Used.
7
Collector Collector of LED-transistor optocoupler. Notifies host com-
puter of absence of a-c input or a major power supply fail-
ure, active “high” (see PAR 1.4.10), requires pin 4 to be
connected to the “–“ of the host computer d-c supply as
described in PAR.2.9.
