3.13. Input Signals
Signals to operate the camera can be input via the terminals on the back of the system's camera.
The signals that can be input are listed below.
A signal other than the specified signal must not be input to the connectors.
Use extreme caution as there is a risk of damage to both devices, the input device and the
output device.
3.13.1. TRIG SW IN Connector
This trigger is input during the READY or ENDLESS recording state by contact between the BNC
connector's shield and a center pin (switch closure). The center pin normally has voltage flowing
through it. Use caution to avoiding contact with other pins.
3.13.2. SYNC IN Connector
The system recognizes a TTL signal from other devices as a synchronization signal.
Input voltage is 0V to +12V (H level +4.5V to +12V), positive or negative polarity, pulsewidth is 50
ns or greater.
Operating current is 10 mA recommended, 30 mA maximum.
