CAUTION
If the board or the connected wire receives noise, or the
distance between the board and the target is long, data may
not be outputted properly.
For analog output signal, the current capacity is ±3mA (Max.).
Check the specification of the connected device before
connecting the board.
Do not short the analog output signal to analog ground,
digital ground, and/or power line. Doing so may damage
the board.
Do not connect an analog output signal to any other analog
output, either on the board or on an external device, as this
may cause a fault on the board.
The following sections show examples of how to connect digital
I/O signals, counter I/O signals, and other control I/O signals
(external trigger input signals, sampling clock input signals,
etc.).
All the digital I/O signals and control signals are TTL
level signals.

About the counter input control signal
Counter Gate Control Input (refer to the page 3 Connector Pin
Assignment) acts as an input that validate or invalidate the
input of an external clock for the counter. This function
enables the control of an external clock input for the counter.
The external clock for the counter is effective when input is
"High", and invalid when input is "Low". If unconnected, it is a
pull-up in the board (card) and remains "High". Therefore the
external clock for the counter is effective when the counter gate
control input is not connected.
CAUTION
Do not short the output signals to analog ground, digital
ground, and/or power line. Doing so may cause damage.
