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 signal control
Counter Gate Control Input (see page 3, Connector Pin
Assignment”) allows the input of the external clock for the counter
to be enabled and disabled. This function can be used to control
the input of the external clock for the counter. When the input
level is “High”, the input of the external clock for the counter is
enabled. It is, on the other hand, disabled, when the input level
is “Low”. Note that when it is not connected, the input level is set
to “High” as the board (card) pins are pulled up. Therefore, the
input of the external clock for the counter is enabled when it is not
connected.
Do not short the output signals to analog ground, digital
ground, and/or power line. Doing so may damage the
board.
The functions same with conventional product of DA16-
16(LPCI)L are provided with the this product. In addition, as
there is compatibility in terms of connector shape and pin
assignments, it is easy to migrate from the existing system.
So you can use the same operating procedures as DA16-
16(LPCI)L.
There are some differences in specifications as shown below.
