PCAN-MicroMod Evaluation Kit
User Manual
3.3
Digital Outputs
The Evaluation Board has 8 digital outputs. The corresponding
connector is J1 (screw terminal on the upper left). The outputs are
low-active and can drive up to 350 mA. The LEDs LD1 to LD8
indicate each status of the outputs. A lighting LED means that the
output is active and is switched against mass.
With solder bridges on positions JP1 to JP8 a pull-up resistor
(3.3 k
Ω
) can be engaged for each output (default: open). With this
modification you gain
TTL
compatible output signals.
With a solder bridge on position JP10 the outputs 0 to 3 and on
position JP9 the outputs 4 to 7 can be
inverted
by hardware
(default: open).
3.4
Frequency Inputs
The Evaluation Board has 4 frequency inputs. The corresponding
connector is J2 (Fin0 to Fin3, screw terminal on the mid left). The
MicroMod can meter frequencies from 1 Hz to 10 kHz.
With solder bridges on positions JP13 to JP16
low-pass filters
consisting of 100 k
Ω
/100 nF can be engaged for each input path.
