Advanced Automotive M2M/IoT Gateway Power Supply The RTCU LX2 pro device must be supplied with 8..36 VDC from an external DC power source connected to the X1 connector. Positive power is applied to the SUPP pin, and the ground is connected to the PGND pin.
The maximum switchable inductance is 20mH and must not be exceeded. The digital outputs are supplied through the X1 power connector that also supplies the rest of the RTCU unit. As the power is also the RTCU LX2 pro main power, a power fail would also affect the digital outputs.
RTCU LX2 pro Technical Manual V1.00 Advanced Automotive M2M/IoT Gateway Digital Inputs / Ignition Input The digital inputs are all low-pass filtered and transient-protected. To activate the inputs, connect a positive voltage between the input and the GND connector. Please note: The DIN 5/IGN input is special as it also functions as the ignition input. If the ignition input is activated with a logical high or low (Wait For Event mode only), it will wake up the unit when the RTCU is in low power mode.
Advanced Automotive M2M/IoT Gateway Analog Inputs / Flex Inputs The RTCU LX2 pro has two analog inputs. The analog inputs are voltage inputs specified with an operating range of 0V to 30V DC. The conversion resolution is up to 12 bit(0..4095).

RTCU LX2 pro Technical Manual V1.00 Advanced Automotive M2M/IoT Gateway The analog inputs are made available at the same time as both normal analog inputs with an operating voltage range of 0-10V DC, and as flex inputs. When used as flex inputs, the inputs are multi-mode inputs that can be configured to operate as either analog or digital inputs.
RTCU LX2 pro Technical Manual V1.00 Advanced Automotive M2M/IoT Gateway CAN Communication Port The RTCU provides the physical layer for the CAN (Controller Area Network) serial communication interface in accordance with the ISO 11898 standard. The CAN bus is designed for high-speed (up to 1Mbit) robust communication in especially harsh environments like those found in the automotive industry.

If the RTCU LX2 pro is used as an endpoint node, the RS485 communication lines can be terminated with 120Ω by using configuration DIP-switch 4, located on the front, behind the end-cap.
RTCU LX2 pro Technical Manual V1.00 Advanced Automotive M2M/IoT Gateway 1-Wire Bus The 1-Wire bus is available on the X2 connector. All 1-Wire communication goes through a single connection, and all 1-Wire devices connected can retrieve power directly from the bus (called parasitic power).
Advanced Automotive M2M/IoT Gateway 3D Movement Sensor The RTCU LX2 pro unit contains a 3-axis accelerometer and 3-axis gyroscope in order to detect both vibration and motion. This sophisticated range of movement sensors allows for detecting movement and position change in 3 directions, X-Y-Z with force as high as 16g in acceleration, 2000 dps in rotation.
RTCU LX2 pro Technical Manual V1.00 Advanced Automotive M2M/IoT Gateway LED Indicators Four bi-colored (red and green) LED indicators are present on the front of the unit (see the graphical overview). Two bi-colored LED (A and B) are available to the user, and the remaining two LEDs (S1 and S2) signal the status and possible errors of the RTCU device.
