1.3 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.
1.3.1

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.

1.3.2

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.
