I/O Signals
Output Signals
• Trig
This pin transmits the TrigBusy signal. A low-level signal upon trigger generation and a
high-level signal upon source operation completion.
• Output
This pin transmits the output state. A high-level signal if the output is off and a low-
level signal if the output is on.
• Ready
This pin transmits the source change completion signal (Ready). This is transmitted
10 ms after the source level changes as a low pulse with a width of 10
μ
s.
Input Signal
• Trig
This pin receives the STEP trigger for program execution. When a falling edge is
received, the GS200 performs the same operation as if its STEP key had been
pressed.
• Output
This pin receives output control signals. When these signals are received, the GS200
performs the same operation as if its OUTPUT key had been pressed. When a falling
edge is received, the GS200 turns output on. When a rising edge is received, the
GS200 turns output off.
