-This section is about the MB6582 control surface trouble shooting based on the PCB version 2.0. Please note that inappropriate working control surfaces ​can have a fault on the control surface PCB as well as on the Base PCB. Therefore it is important to disconnect the CS PCB from the base PCB in order to separate the root causes of the various possible faults.+This section is about the MB6582 control surface trouble shooting based on the PCB version 2.0.

 It is also recommended to use this guide to verify the function of your control surface during the build process. This will help you to identify faults early during the assembly process and will make you live easier while testing the completed synthesizer. It is also recommended to use this guide to verify the function of your control surface during the build process.

   - Indicator LED’s -> Use the cable described in point a) above to check the wiring from the connection points. You need to connect the GND wire to one connection point on the JD8 pad and the +5V wire to one connection point on the JD7 pad. Please use the LED Assignment Matrix shown below. You need to check all individual LED’s to make sure that they are working as expected. During this test only single LED’s should light up. If more than one LED’s lights up then you have got a short on the PCB.   - Indicator LED’s -> Use the cable described in point a) above to check the wiring from the connection points.

   - Switches -> The function of the switches can easily be tested with the diode mode on your Multimeter. You need to connect the GND wire of your Multimeter to one connection point on the JD8 pad. The positive wire (red) has to be connected to one connection point of the JD5 pad. Please use the Switch Assignment Matrix to identify the correct connection point on the JD8 and JD5 pads. You should now press down the switch and check on your Multimeter display if it is working appropriately. With this check you won’t be able to identify shorts on the GND part of the board. To exclude shorts on the JD8 GND pad you need to measure the resistance between each connection point on the JD8 pad.   - Switches -> The function of the switches can easily be tested with the diode mode on your Multimeter.

-  - Encoders -> The encoders are connected to the connection pads JD1 to JD4 as well as JD9. Please refer to the Encoder Assignment Matrix and the Base PCB / CS PCB Connector Overview. You can used the continuity mode (2K Skale) to check the encoders. You need to connect the wires from the Multimeter to the connection points of JD1 to JD4 as well as JD9. +  - Encoders -> The encoders are connected to the connection pads JD1 to JD4 as well as JD9.

 If you haven’t found any faults so far you can start testing your CS while connected to the Base PCB. Please use the following verification sheet to test the function of each component of the control surface: If you haven’t found any faults so far you can start testing your CS while connected to the Base PCB.
