Analog Output – SRL 30
The SRL 30 has 4 x 14-bit analog output channels with a range of ±10 volt. These channels
are very easy to program. A single command is used to write to them.
Writing to a DAC channel
A single call is necessary to set a voltage on a DAC channel. The table below shows the
relation between the software channel and the channel on the connector.
