2nd COM wiring |
'2nd COM wiring |
2nd COM port for live data (FW 1.2.35 and newer), 2nd RS232 3 pin (unpopulated header) towards the main processor:
* GND (easy to locate) * TX (measures appr -7V when idle) * RX (input, as an experiment pull to +5V with 1k resistor and it will follow to 3..4V perhaps). |
Looking to make use of the 2nd COM port for live data (FW 1.2.35 and newer), where do I find RX and TX for the 2nd port on the main board? |
Located above the MAX232D (SOIC16) chip, different header, otherwise the same pinout as the 1st RS232 (which is towards the L293D stepper driver IC). See GenBoard/VerThree/Schematic |
