This page contains frequent questions related to the Low Cost DCC Controller.
Answers may also be found on the LC-DCC forum.
Windows 10 USB3 communications not workingCheck the status of the USB port using the Windows 10 device manager. If the port is displayed as not working or not started then try and turn off Windows 10 USB power management, this link can help. Also try using a USB HUB to connect to the LC-DCC controller.
Potentiometers do not seem to work Use a terminal and the LC-DCC commands ?ADC, POT1, POT2 etc. to check the ADC and potentiometer status. When first powered the LC-DCC system needs to measure the maximum and minimum volatges so move all potentiometers from minimum to maximum position before using the LC-DCC system. The LC-DCC system will however automatically check the volatges if not set (i.e. potentiometer not at maximum setting). Once the maximum and minimum voltages have been established the potentiometer is enabled and ready for use. If you set the engine address for the potentiometer or command an emergency stop then the potentiometer MUST BE MOVED TO THE CENTER (zero speed) position before the potentiometer will become active again.
CV Values are always read as zero in Service Mode Check connections to programming track are good. Check power supply is on.
Engine moves during CV reading & writing This is common as the engine powers the motor to signal acknowledge back to the DCC controller.
M3/M4 Software Not Working Verify using the programming tools that the software has been loaded into flash. Look at the board LED and reset the board. The board LED should flash once a second after power up in IDLE state.
