4.4.2 Analog output
H
Single ended output.
H
Voltage range: 0-11V.
H
Output current: 30mA maximum.
The analog output provides an independent opto-isolated 0-11V output for controlling an
additional axis or other external equipment. The output is controlled using the
AUXDAC
keyword - see the MintMT help file. Output offset voltage can be controlled by the variable
resistor R35, located just behind the SOUT and SGND pins of the Misc connector.
