6.3.2 Connecting the switching input/output
The BCL 8 is provided with a switching input or a switching output. You can configure the
respective function (input or output) according to your requirements using the supplied
BCLConfig software.
Switching input (default)
By means of the SW IN/OUT combined switching input/output connection, you can trigger a
read process in the standard setting (low = active) with the connection SW IN/OUT (pin 5)
and GND (pin 3). The 2.2 kΩ "pull-up" resistor must be connected externally (connection
version 1, figure 6.4).
Figure 6.4: Switching input for BCL 8 connection version 1 (standard setting)
With the "inverted" setting (high = active), you can trigger a read process by applying a
voltage of +5 V DC (pin 1) at SW IN/OUT (pin 5) (connection version 2, figure 6.5).
