3.11. Using External Triggers
With the system, you can record by receiving various trigger signals matched to the recording
application. The trigger signals that can be used on the system are explained here, along with a
description of how to use them.
3.11.1. Inputting an External Trigger Signal
The external trigger signals that can be used with the system and their input system are listed below.
You can change External trigger signal input settings by PFV.
The signals input from the TRIG TTL IN and GENERAL IN connectors are explained in section
"2.2.7. I/O Port Connector".
Connector Name
(Input System)
Setting Signal
TRIG TTL IN
TRIG POS
FET Input 0V - +12V (L level +1.0 or less, H level
+2.8V to +12V), Positive Polarit
TRIG NEG
FET Input 0V - +12V (L level +1.0 or less, H level
+2.8V to +12V), Negative Polarity
GENERAL IN
TRIG POS
FET Input 0V - +12V (L level +1.0 or less, H level
+2.8V to +12V), Positive Polarity
TRIG NEG
FET Input 0V - +12V (L level +1.0 or less, H level
+2.8V to +12V), Negative Polarity
TRIG SW IN None Contact signal
Set the signal type to be input to GENELAL IN from the PFV in advance.
Use caution not to input more than specified voltage to the TRIG TTL IN and GENERAL IN
trigger signal inputs as there is a risk of damage to the equipment.
