The Kmoon Obd2 Mini Interface is a powerful tool for vehicle diagnostics and communication. This guide delves into its functionality, highlighting key features and providing a clear understanding of its capabilities. We’ll explore the device’s interfaces, indicator lights, and connector pinouts.
Decoding the kmoon obd2 mini interface Hardware
The kmoon obd2 mini interface, much like the RAD-Moon discussed here, is designed with user-friendliness in mind. Its components are strategically placed for easy access, even in tight spaces. Let’s break down the device’s two main sides: the Conventional Ethernet Side and the Automotive Ethernet Side.
Conventional Ethernet Connectivity
This side of the kmoon obd2 mini interface connects to a standard Ethernet network. It features two essential ports:
- RJ-45 Port: This is a standard Ethernet jack for connecting to your network. It allows the device to communicate with computers and other network devices.
- Mini-USB Port: This port provides power to the kmoon obd2 mini interface. A standard mini-USB cable connects the device to a power source.
Figure 1: Conventional Ethernet Side of the kmoon obd2 mini interface. The RJ-45 port (left) includes integrated Link (green) and Activity (orange) LEDs. The mini-USB port (right) powers the device.
The RJ-45 port incorporates two LEDs that provide vital connection status information:
- Link LED (Green): A solid green light confirms a successful connection between the kmoon obd2 mini interface and another Ethernet device.
- Activity LED (Orange): This LED flashes when data is being transmitted or received, indicating active communication.
A consistently lit green Link LED and a flashing orange Activity LED signify normal operation. The Activity LED’s flashing speed reflects the data transfer rate – faster flashing indicates higher data throughput. The kmoon obd2 mini interface, like other OBD2 devices, supports both 10 Mb/s and 100 Mb/s Ethernet speeds, automatically negotiating the optimal speed with the connected device.
Automotive Ethernet Connectivity
The Automotive Ethernet side of the kmoon obd2 mini interface facilitates communication with the vehicle’s network. It typically uses a Molex Mini50 connector, a common interface for BroadR-Reach devices. This connection automatically configures itself as master or slave, ensuring seamless communication.
Figure 2: Automotive Ethernet Side with BCM89810 PHY. The central Mini50 connector links to the vehicle’s network. Status LEDs (left) indicate Link status (green), Errors (red), Data Reception (Rx – green), and Data Transmission (Tx – green).
LED Indicators for BCM89810 PHY:
- Link LED (Green): Illuminates when connected to an active Automotive Ethernet device.
- Error LED (Red): Flashes if a data transmission error occurs.
- Rx LED (Green): Flashes when data is received.
- Tx LED (Green): Flashes when data is transmitted.
Figure 3: Automotive Ethernet Side with TJA1100 PHY. This version features a Link LED (green) and an Rx LED (green) that dims when receiving significant traffic (minimum 5Mbps).
LED Indicators for TJA1100 PHY (Serial Number > 023599):
- Link LED (Green): Illuminates when connected to an active Automotive Ethernet device.
- Rx LED (Green): Dims when receiving substantial data traffic (above 5 Mbps).
Understanding the BroadR-Reach Connector
The BroadR-Reach Mini50 connector is crucial for the kmoon obd2 mini interface’s automotive communication.
Table 1: BroadR-Reach Mini50 Pinout
| Pin # | Label | Description |
|---|---|---|
| 1 | No Connect | |
| 2 | TRD+ | Data transmit and receive, positive |
| 3 | TRD- | Data transmit and receive, negative |
| 4 | No Connect |
