9.2 External Signal Output (Trigger Output)
164
You can output a signal when a trigger event occurs. This allows synchronous
operation of multiple HiLoggers by parallel triggering (p. 166).
9.2 External Signal Output (Trigger Output)
Pulse wave is output.
(TRIG.OUT)
Trigger event occurs
Trigger Output Signals
Output signal Open collector output (with voltage output), active LOW
Output voltage
range HIGH level: 4.0 to 5.0 V, LOW level: 0 to 0.5 V
Pulse width LOW level: 10 ms or greater
Maximum input
voltage -20 to +30 V, 5 mA max, 200 mW max
HIGH
4.0 to 5.0 V
LOW
0 to 0.5 V
GND
TRIG.OUT
10 k
Ω
5 V
10 ms or greater
The signal is output even when triggering is not enabled. When triggering is
not otherwise used, a trigger signal is output during measurement.
Signal Output Procedure
Connect the HiLogger's TRIG.OUT external control terminal to the external
device to be triggered.
(See the connection procedure on p. 45 )
When a trigger event occurs, a pulse wave changing from the HIGH level (4.0 to 5.0 V)
to the LOW level (0 to 0.5 V) is output from the TRIG.OUT terminal.
