ADR-CR(OUT) ： This signal clears the external address c unter.
ADR-CK(OUT) ： This is cl ck signal f r external address c unter.
Please c unt up at the rising f this signal.
CLR(OUT) ： When receiving SDC c mmand r DCL c mmand fr m the GP-IB c ntr ller,
it utputs 2µs negative pulse.
TRG(OUT) ： When receiving GET c mmand fr m the GP-IB c ntr ller, it utputs 2µs
negative pulse.
RESET(OUT) ： It utputs the LOW level signal when the p wer ON and reset signal is input.
RESET(IN) ： Input f r external reset switch with pull-up resist r 10kΩ.
LED TLK(OUT) ： Output f r the lighting the external LED with current limiting resist r 1kΩ.
It bec mes the LOW level at the talker.
LED LSN(OUT) ： Output f r the lighting the external LED with current limiting resist r 1kΩ.
It bec mes the LOW level at the listener.
LED SRQ(OUT) ： Output f r the lighting the external LED with current limiting resist r 1kΩ.
It bec mes the LOW level when SRQ is generated.
LED RMT(OUT) ： Output f r the lighting the external LED with current limiting resist r 1kΩ.
It bec mes the LOW level when it is rem te perati n.
