Parameter Mode
can be entered by simply pressing and holding the Enter button down for three
seconds. Once in Parameter Mode, the far left of the display will be a ‘P’. The right side of the display
will indicate the currently selected parameter number for editing purposes. Pressing the Up or
Down button will increase or decrease the selected parameter number on the display. Although the
parameter numbers are in numerical order, some numbers are skipped. These skipped numbers
represent reserved parameters that are not yet implemented and are not displayed. Once the desired
parameter number is displayed, pressing the Enter button will change the display to Value Mode.
Value Mode
is used to modify the value of the selected parameter. When in Value Mode, the two
dots which form the colon between digits two and three, will alternately flash (one, then the other.)
Pressing the Up or Down button increases or decreases the selected parameter’s value. See the
Software Parameters for a list of allowable values and ranges. Value changes take effect immediately.
Once the desired value is showing in the display window, pressing the Enter button again will return to
Parameter Mode. The new value is not saved in permanent memory until the Enter button is pressed.
Removing power from the unit while in Value Mode may result in the specified new value being lost.
The front panel Annunciators will be perform as follows:
•
Parameter 10 = 1; ‘Gen’ annunciator lit
•
Parameter 10 = 2; ‘SCL’ annunciator lit
•
Parameter 30 = 7, IN1 = Low; ‘SCL’ annunciator lit
•
Parameter 35 = 7, IN2 = High; ‘SCL’ annunciator lit

Configuration is accomplished via jumper settings and (for Voltage Outputs only) a trimpot
adjustment. Location is as follows:

With the display set to 100.0 and no user device connected to ‘V-OUT’, P3-5 (-) and P3-6(+), adjust R9
for the desired maximum V-OUT. Finally, connect the user device and carefully re-adjust R9 to trim
the output to desired maximum V-OUT. This will prevent the output from exceeding the limits of the
user device if done properly. The user should evaluate what their system will be doing during this
adjustment to prevent any harmful results.

There are three Modes of Operation for the GSDA-DP-S, established by the JP1, JP3, and JP4 jumper
settings:
