1.3 Features
The plug-on board of type ME-5001 is a 48 bit digital I/O board with
bit-pattern detection for the base boards of the ME-5000 series. You can
configure individual subdevices alternatively for frequency measurement
resp. pulse generator on demand (see chapter 4 from page 21).
Overview:
*Alternative configuration can be activated via ME-iDC.
• Digital I/O ports : The ME-5001 has totally 48 bi-directional I/Os.
The direction can be defined for each of the six 8 bit ports
(subdevice 0..5) by software. After powering up, all the ports are
configured as inputs.
• Frequency counter: The concept of the "configurable subdevices"
allows subdevice 0 to be employed as a frequency counter. Eight inde-
pendent channels are available for measuring the frequency and duty
cycle of rectangular signals (max. 5.5 MHz).
• Pulse generator : The concept of the "configurable subdevices"
allows subdevice 1 to be employed as a rectangular wave generator.
Eight independent channels are available for the output of a periodic,
rectangular signal at up to 5.5 MHz with a variable duty cycle.
• Signal level 3.3 /5 V : The signal level of all the digital inputs/outputs
and of the control lines can be switched together between 3.3 V and
5 V, depending on the external circuitry. The changeover is made for
all the ports of the plug-on board at once using software.
• For optimum signal matching, you are able to activate, via software,
an
active 110
Ω
termination at the digital inputs/outputs of the
subdevices 0..3.
