Digital I/O signals and Control signals

Connection

This section shows an example of how to connect digital I/O signals and the control signals (external

sampling clock input signals) using flat cable.

Connect the interface connector and external device using a cable such as a separately purchased flat

cable (PCA37P).

All the digital I/O signals and control signals are TTL level signals.

CAUTION

Do not short the output signals to analog ground, digital ground, and/or power line. Doing so may

damage the PC card.
