JP1 (Program Enable Jumper)
The JP1 jumper is located under the dust cover on the back end of the upper board. When the jumper
is set to the “Off” position, all programming features are “locked out” from the front panel user. When
the jumper is in the “On” position, the programming Items are open to change. JP1 is shipped from
the factory set in the “On” position.

1) Press and hold the Enter button until Parameter Mode is entered. The ‘Parm’ LED indicator will
light up.
2) Using the Up and Down arrow buttons, move to the desired parameter number you wish to view
or edit.
3) Press the Enter button to change the value of the selected parameter. The ‘Valu’ LED indicator
will light up.
4) Using the Up and Down arrow buttons, change the parameter setting to the desired value.
5) Press the Enter button to accept the new parameter value. (Returns to Parameter Mode).
6) Select parameter Zero (“0”) and press the Enter button to return to Run Mode.
Operating the User Interface
Although the GSD8 user interface is very versatile, it is also simple to setup and operate. With just
a few button presses, it allows the user to configure a number of adjustable Parameters. The LED
display has three basic operating modes: Run Mode, Parameter-Selection Mode, and Value Mode.
“Parameter” and “Value” modes have LED indicators that aid the user in determining the current state
or mode of the user interface.
NOTE: Parameter and Value Modes can only be entered if the Program Enable jumper (JP1) is in the
“On” position.
