Connecting the Digital I/O and Control Signal
This section shows how to connect the digital I/O signal and control signal (“External Sampling Clock
Input”, “External Trigger Input” and so on) by using a flat cable.
Connect CN1 to the external device by using the optional flat cable (PCA96P-1.5).
All the digital I/O signals and control signals are TTL level signals.

Figure 3.12. Connecting the Digital Output
Do not short the output signals to analog ground, digital ground, and/or power line. Doing so may
damage this product.
Reference
For the operation timings for control signal input, see “Timing of External Control Signals” in
