Chapter 5 PC Operation - Tutorial
Note - when set to an analog input the 'I/O 1' port is dedicated to be the external feedback signal input. Therefore if the 'Input
Signal Source' (described above) is selected to be '0-2V SMA input' the mode for 'I/O 1' is automatically selected to be '0-2V
Input - F/B Source'.
Note - when set to an analogue output the 'I/O 2' port is dedicated to be a monitor signal for the optical feedback source (at
the current range setting for optical input i.e. equivalent to the relative signal bar on the main panel).
I/O 1 Polarity, I/O 2 Polarity - sets the polarity of the 'I/O 1' and 'I/O 2' connectors when in digital mode. A setting of 'High' means
that logic high (TTL 5V) equates to active high. A setting of 'Low' means that logic low (TTL 0V) equates to active high.
Display Int. (Intensity)
- Determines the brightness of the control panel display. Enter a value from 0 to 255.
Wheel Step Size
- The thumbwheel on the to panel is used to control the HV outputs 'HV OUT 1' and 'HV OUT 2' selected
using the menu system on the unit. This parameter sets the sensitivity of the thumbwheel to
Low
,
Mid
or
High
, where..
Low - Most turns of the thumbwheel to control output voltage (highest resolution)
High - Least turns of the thumbwheel to control output voltage (lowest resolution)
Persist Settings to Hardware -
Many of the parameters that can be set for the NanoTrak K-Cube can be stored (persisted)
within the unit itself, such that when the unit is next powered up these settings are applied automatically. This is particularly
important when the driver is being used manually in the absence of a PC and USB link. The
Input Signal Source
parameter
described previously is a good example of a setting that can be altered and then persisted in the driver for use in absence of
a PC.
To save the settings to hardware, check the ‘Persist Settings to Hardware’ checkbox before clicking the ‘OK button.
