3.17. Input / Output Signal Types
With the system, many signals can be input and output through the I/O cable. Signals that can be
input and output from the I/O cable are listed below.
A signal other than the specified signal must not be input to the various connectors.
Use extreme caution as there is a risk of damage to both, the input device and the output device.
3.17.1. TRIG TTL IN Connector
The system recognizes an external TTL signal as a trigger during the READY or ENDLESS
recording state. Starting and stopping recording (in the selected recording mode) is controlled with
this signal.
Input voltage is 0V to +12V (H level +2.5V to +12V), positive or negative polarity, pulse width is 200
ns or greater.
3.17.2. TRIG TTL OUT Connector
A 5V TTL trigger signal is output for input to an external device.
3.17.3. 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.
3.17.4. SYNC IN Connector
The system recognizes a TTL signal from other devices as a synchronization signal.
Input voltage is 0V to +12V (H level +2.5V to +12V), positive or negative polarity, pulse width is 200
ns or greater.
