nel and is always applied to it. Function
rspio2_ConfigureChannelCurrentLimit
facilitates this setting.
5.1.6 Output of static voltages
In the basic state of the module, all outputs are in the „Analog“ operating mode. If nec-
essary, this mode can also be selected with function
rspio2_ConfigureChannelMode
.
The voltage can be adjusted channel-specifically with function
rspio2_ConfigureChannelLevels
Parameter „Output High Level“ determines the
output voltage.
5.1.7 Output of static digital bit patterns
A channel can be switched to „Digital Static“ mode using function
rspio2_ConfigureChannelMode
. Any number of channels can be operated in this
mode. Depending on which bit pattern is programmed, either the channel-specific volt-
age „Output High Level“ or the voltage assigned to a group „Output Digital Low
Level“ is generated.

The pattern value for channels in „Digital Static“ mode can be set with function
rspio2_SetDigitalOutputState
One parameter of this function serves as a
mask so that the individual channels can be operated.
When switching from the „Analog“, „Waveform“ or „Square Wave“ mode to „Digital
Static“ mode, level „Output High Level“ is generated (pattern value „1“).
5.1.8 Output of dynamic digital bit patterns
In the „Digital Dynamic“ operating mode, the output voltage of the relevant channels is
determined by a digital bit pattern which is updated cyclically after sequence control
begins (see Section 5.1.13).
This mode can be selected for a channel using function
rspio2_ConfigureChannelMode
. Any number of channels can be switched to this
mode.
The high and low level for the relevant channels can be set like in „Digital Static“ mode
(see Section 5.1.7).
