the switch until the LED flashes.
12.
To go into standby, depress the switch for approx. 1 second.
If the controller works without issues and you have purchased the Speed Sensor move
on to the adaptive speed control (PID) step. This section requires critical placement
and adjustment of the IR sensor which you will do after a brief overview of the
configuration menu and software.

Configuration menu and tuning software
It’s best to get your turntable platter spinning first without using the IR platter sensor
and PID control. The motor controller is pre-configured with a set of defaults that
assume you are using a 110v synchronous 2 phase motor. These defaults should get
you through the basic testing for the board.
To configure the board for basic testing use the PIDTuning application (or a serial
console application set to 9600,N,8,1). Interaction with the controller firmware is via
the serial command input and output area:
A configuration menu should be displayed upon initial connection. Note that in later
steps when PID tuning the menu will not display, however, you can always get the
menu to print by inputting the “M” character (not case sensitive) in the Serial Cmd:
Input area and pressing Enter/Return (CR). Any values that you input will remain in
place until power is removed unless you use the Write Current Values to EEPROM
option. On controller power up the EEPROM values are read back into the program.
Your Anti-Virus (AV) program may block the PIDTuning.exe program or show a
warning – this is normal as the program is not digitally signed. You may need to
create an exception in your AV software.
