Technical Manual for the RTCU MX2i eco - Logic IO

Technical Manual 1.03, RTCU MX2i ecoSerial port 1 / Programming port.This port can be used as general-purpose RS232 serial port or as a programming port. Inorder to use the port for programming, the RS-DET pin must be connected to GND. Whenusing the port as general-purpose RS232, the RS-DET pin must be left unconnected.Further details on the programming cable are available in the RTCU-IDE online help.X4: 6 pin SER1 connector overview.Pin Name Description1 TD Transmit Data from serial port 1, RS232 compatible4 RD Receive Data for serial port 1, RS232 compatible2 RS-DET Programming cable detect, normally unconnected (if programmingcable, connect to GND)5 SGND Signal GroundDC-OutA 3.3VDC output is available on the 6 pin serial port 1 connector. It is possible to controlthe output in order to save power. The output is short circuit- (to ground), ESD- andtransient protected.Make sure not exceed the current specification of the output and be aware of inrushcurrents of the external equipment may exceed the specifications. It is recommended toinstall a fuse to protect the output.This output must be enabled from the application. Please consult the RTCU-IDE onlinemanual for more information.X4: 6 pin SER1 connector overview.Pin Name Description3 DC-Out +3.3V/150mA DC-Out for external equipment.5 SGND Signal GroundVibration SensorThe RTCU MX2i eco unit contains a vibration sensor. It makes it possible through thepower management to detect vibrations when for example the vehicle is moved. Thesensitivity can be altered from within the VPL program - making it suitable for variousapplications. Please consult the RTCU-IDE online manual for more information.Page 11 of 18Logic IO ApS.
