Digital I/O signals and Control signals
Connection
The digital I/O signals and the control signals (external trigger input signal, sampling clock output
signal and so on) are interfaced through the connector CN2. User can use an optional flat cable DT/E1
or DT/E2 (with bracket and a 15-pin D-SUB female connector) to connect these signals to your external
devices.
All the digital I/O signals and control signals are TTL level signals.
