To put the console into service mode, the RMC/test mode test point needs to be grounded. This is necessary when recalibrating the drive and doing other stuff.

=How to connect=
To enable the UART interface, the console must be put into testmode by pulling the TEST_MODE0 test point to ground. The interface operates at '''57600 baud 8N1''' (automatically set correctly by PMAP and the official service tools) and rather non-standard '''3.5&nbsp;V'''.


3.3&nbsp;V signal levels work fine for communication, but care must be taken not to additionally connect an internal 3V3 voltage regulator, which is provided on some USB UART interfaces, to the console, since this will conflict with the console's own 3V5 voltage regulation and could damage the USB device and/or the console. On such interfaces, it should suffice to '''just connect Rx, Tx and GND'''. Even better would be to use a RS-232-to-TTL level shifter, which can take the 3V5 voltage as reference directly from the console itself.


==Notes==
*'''RX''' and '''TX''' are sometimes swapped in these pictures. This is due to the contributors not having unified their naming conventions, with some marking RX and TX as seen from the MechaCon's side and others marking RX and TX as seen from the PC's (or it's interface's) side. If you can't establish a connection one way, you should try swapping RX and TX and try again. There are plans for unifying the naming in the future.
*The '''3.3V''' marked on most pictures are '''actually 3.5V''', since that's what MechaCon runs off. If you are using e.g. a RS232-to-TTL level shifter (like e.g. a MAX3232-based level shifter), the PS2's 3.5V need to be connected to your level shifter's Vcc. However, it should not be connected to anything that has it's own 3.3V regulator (like e.g. some USB-to-TTL converters), since the regulator on the PS2's board and your converter will end up in a feedback loop, potentially causing damage. There are plans for unifying the naming in the future.
*'''RMC''' is actually named '''TEST_MODE0'''. This mistake comes from the fact that the generic microcontroller that the SPC970-MechaCon is based on has an alternate function on the same pin called RMC ('''R'''e'''M'''ote'''C'''ontroller), which is an internal remote control signal decoder. This alternate function is unused on PS2 and does not exist on the Dragon-MechaCon. There are plans for unifying the naming in the future.
