Figure 3.7. Output Circuit
The output circuits of interface blocks of this product is illustrated in Figure 3.7.
The signal output section is an Optocoupler isolated, open-collector output (current sink type).
Driving the output section requires an external power supply.
The rated output current per channel is 100mA at maximum.
The output section can also be connected to a TTL level input as it uses a low-saturated transistor for
output. The residual voltage (low-level voltage) between the collector and emitter with the output on
is 0.5V or less at an output current within 50mA or at most 1.0V at an output current within 100mA.
A zener diode is connected to the output transistor for protection from surge voltages. A
PolySwitch-based overcurrent protector is provided for every 8 output transistors. When the
overcurrent protector works, the output section of this product is temporarily disabled. If this is the
case, turn of the power to the PC and the external power supply and wait for a few minutes, then turn
them on back.
CAUTION
When the PC is turned on, all output are reset to OFF.

5. Function
This section describes the features of this product.
Data I/O Function
Data Input
When input data is “ON”, “1” is input to the relevant bit.
When the input data is “OFF”, in contrast, “0” is input to the relevant bit
Data Output
When “1” is output to the relevant bit, the corresponding transistor is set to “ON”.
When “0” is output to the relevant bit, in contrast, the corresponding transistor is set to “OFF”.
CAUTION
When the PC is turned on, all output are reset to 0 (OFF).
Monitoring Output Data
This product can read the state of the data currently being output without affecting the output data.
DIO-3232LX-USB

5. Function
Digital Filter
Using this feature, this product can apply a digital filter to every input pin, thereby preventing wrong
recognition of input signals from being affected by noise or chattering.
Digital Filter Function Principle
The digital filter checks the input signal level during the sampling ti me of the clock signal. When the
signal level remains the same for the digital filter set time, the digital filter recognizes that signal as the
input signal and changes the signal level of the PC
If the signal level changes at a frequency shorter than the set time, therefore, the level change is ignored.

Interrupt Control Function
This product can use all of the input signals as interrupt request signals.
This product can generate an interrupt request signal to the PC when the input signal change from High
to Low or from Low to High.
When the digital filter (described above) is used, interrupt requests are generated by input signals that
have passed through the filter.
Disabling/enabling Interrupts
Interrupt mask bits can be used to disable or enable the individual bits for interruptions.
Once a certain bit has been interrupt-disabled, no interrupt occurs even when the corresponding input
signal changes its level.
To let interrupts occur, enable the corresponding interrupt mask bit for interruptions.
CAUTION
All of the interrupt mask bits are interrupt-disabled when the power is turned on.
Selecting the Interrupt Edge
Interrupt edge select bits can be used to set the input logic for interruption bit by bit.
If you set an interrupt edge select bit to 0, an interrupt occurs when the input value to the corresponding
bit changes from 0 to 1 (at the fall of the input signal from High to Low).
If you set an interrupt edge select bit to 1, an interrupt occurs when the input value to the corresponding
bit changes from 1 to 0 (at the rise of the input signal from Low to High).
CAUTION
When the power is turned on, all of the interrupt edge select bits are set to 0 so that an interrupt
occurs when the input value changes from 0 to 1 (at the fall of the input signal from High to Low).
Clearing the Interrupt Status and Interrupt Signal
Interrupt status bits are used to identify the input signal bit being used for requesting an interrupt.
When an interrupt status is input, the interrupt request signal and the in terrupt status are cleared
automatically.
CAUTION
- All of the interrupt status bits are set to 0 when the power is turned on.
- If an interrupt mask bit has been set to disable interrupts, the interrupt status bit is not set even
when the input signal changes its level.
