Digital Channels
The PCI-BASEII features two digital ports with
16 inputs or outputs each. The lines are
bidirectional and set in groups of eight. The
connections are designed as two 20-way pin
connectors (male) on the board (see Figure 1,
p.3).
•
Pin connector K6 => port A, line 1..16
•
Pin connector K5 => port B, line 1..16
•
The digital inputs and outputs are protected
by serial resistors!
•
At PC start, port A is set to input, port B to
output.
•
Digital
inputs
will
always
be
read
synchronously in time together with the
analog inputs.
•
Make sure the digital outputs of the device do not drive against the outputs of your signals.
With the optional accessory ZUKA16 (see
chapter 5, the digital channels are led to an
additional 37-pin D-Sub female connector
(connect line 1 (colored) of ZUKA16 with pin 1
of the pin connector K5 (square pad), attach 2.
connector in parallel to K6).
The right figure shows the connection of the pin
plugs K5, K6 with the D-Sub37 of a ZUKA16.
