Protocol
Modbus RTU. Baudrate defaults to 9600 and modbus address to 001, both can be changed by holding V/▲ at power on.
Manual Operation
The dial is used to change values, pressing the dial in changes the selected digit. Holding in for 3s enables the keylock.
V/▲ selects the voltage target; holding for 3s selects the M1 preset.
A/▼ selects the current limit; holding for 3s selects the M2 preset.
SET brings up the settings menu; holding for 3s allows selecting any preset from M1-M9 using the dial.
When a preset is selected it is automatically copied into preset M0, which is the active setting.
Settings menu allows configuring of the over-voltage, over-current and over-power protection thresholds as well as saving to presets M1-M9. Arrows select option, dial button selects value and digit, SET exits option or menu.
Status on power up
Can be configured with the S-INI option in the settings menu. Default is off. Selecting a preset will overwrite this value. The ON/OFF setting in M-PRE determines the output state when the preset is selected. OFF will turn the output off, ON will maintain the current output state.
Saving a preset
In the settings menu, set M-PRE to desired preset (M1-M9). Change other options as desired. Return to the M-PRE setting (the value must be selected) and hold SET for 3s. Do not exit the menu before this or the settings will be lost.
