results in an output signal of maximum 50 kHz. By using the wiring
shown in diagram 4, the functions
can be used which
greatly simplifies programming (see also ME-iDS manual).
The output signal is always available at the output of the third
counter of each counter component (OUT_2, OUT_5…).
3.3.4 Pull-Up/Pull-Down Resistors
On a power-up, all digital ports are set to input. Because of this
the corresponding input lines are all set to high impedance (with-
out external wiring). Depending on the application, it may be
desirable to have the digital lines in a defined state on power-up.
The ME-1400 series allows the user to add pull-up or pull-down
resistors to the circuit board directly. Appropriate resistor arrays
can be used (4.7 k
Ω
recommended) port by port. Note, that by
using pull-up resistors, the output current is decreased
accordingly (e.g. with R
up
=4.7 k
Ω
, I
max
=1.6 mA).
