3. Setup Guide
Follow these steps to set up your SE1001 Pro module:
3.1. Power Connection
The SE1001 Pro offers two power input options:
- Type-C Port: Connect the provided Type-C data cable to the Type-C port on the module and to a compatible 5V 0.5A USB power source.
- DC Power Interface: Connect the 12V 1A power adapter to the DC power interface. This port supports a wide input range of 5V to 32V, making it compatible with various vehicle power supplies.

3.2. T1 Port Connection
The SE1001 Pro is equipped with three T1 interfaces. These ports support TE Connectivity and Rosenberger connectors, including a 3.8mm 2-pin interface for flexible wiring. Connect your automotive Ethernet T1 cables to the appropriate T1 ports.
3.3. RJ45 Port Connection
Connect a standard Ethernet cable from the RJ45 port on the SE1001 Pro to your computer or network device. The RJ45 port supports both 1G (1000M) and 100M speeds.
4. Operating Instructions
4.1. DIP Switch Configuration
The DIP switches on the module control the rate selection, master/slave mode, and automatic/manual mode. Refer to Figure 2 for the location of the DIP switches.
- DIP Switch 1 (Rate Selection):
- ON: 1000M (1G) mode
- OFF: 100M mode
- DIP Switch 2 (Master/Slave Mode Selection):
- ON: Master mode
- OFF: Slave mode
- DIP Switch 3 (Automatic/Manual Mode):
- Automatic Mode: When DIP switch 3 is set to ON (labeled 'Auto'), the device will automatically link to both regular automotive Ethernet and Legacy Ethernet. In this mode, DIP switches 1 and 2 are inactive. When using automatic mode, connect the T1 signal first, then the RJ45 signal.
- Manual Mode: When DIP switch 3 is set to OFF (labeled 'Man'), DIP switches 1 and 2 become active, allowing manual configuration of rate and master/slave settings.
4.2. Indicator Lights
The module features several indicator lights to provide status information:
- Red Indicator Light (RUN): Flashes during normal operation.
- Green Indicator Light (T1 Link/Act): Indicates the T1 connection and communication status.
- Off: Not connected.
- Solid Green: Connection successful.
- Flashing Green: Communicating data.
- RJ45 Indicator Lights:
- Solid Green: 100M mode linkUP.
- Flashing Green: 100M mode Activity.
- Solid Yellow: 1000M mode linkUP.
- Flashing Yellow: 1000M mode Activity.
- SQI (Signal Quality Indicator): A 4-digit LED display showing signal quality (25%-50%-75%-100%).
4.3. Sound Prompts
The device provides audio feedback for T1 link status:
- One short beep: T1 Link successful.
- Two short beeps: T1 Link disconnected.
4.4. Legacy Mode
The SE1001 Pro supports Legacy Mode. To enable this, set DIP switch 3 to automatic mode as described in section 4.1.
5. Maintenance
To ensure optimal performance and longevity of your SE1001 Pro module:
- Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the module to extreme temperatures, humidity, or direct sunlight.
- Ensure all cable connections are secure and free from damage.
- Do not attempt to open the casing or modify the internal components, as this will void any warranty.
6. Troubleshooting
If you encounter issues with your SE1001 Pro, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on (RUN light off) | No power or incorrect power supply. | Check power connections. Ensure Type-C is 5V 0.5A or DC is within 5-32V. Try a different power source or cable. |
| T1 Link/Act light is off | No T1 signal, incorrect T1 cable, or incompatible T1 device. | Verify T1 cable connection. Ensure the connected automotive Ethernet device is active and compatible. Check DIP switch 3 for automatic mode. |
| RJ45 Link light is off | No RJ45 connection or incorrect cable. | Check RJ45 cable connection to your computer/network. Ensure the RJ45 port on the connected device is active. |
| Incorrect data rate (e.g., stuck at 100M) | DIP switch 1 setting is incorrect or device is in automatic mode. | If in manual mode (DIP switch 3 OFF), adjust DIP switch 1 for 1G or 100M. If in automatic mode (DIP switch 3 ON), ensure T1 signal is connected first. |
| Master/Slave mode issues | DIP switch 2 setting is incorrect or device is in automatic mode. | If in manual mode (DIP switch 3 OFF), adjust DIP switch 2 for Master or Slave. Ensure the setting matches the connected device's requirement. |

8. User Tips
- For initial setup, it is recommended to start with DIP switch 3 in 'Auto' mode to allow the device to automatically detect the Ethernet type.
- When using the 3.8mm 2-pin terminal block for T1 wiring, ensure correct polarity and secure connections to prevent signal loss.
- Always connect the T1 signal before the RJ45 signal when operating in automatic mode for optimal link establishment.
- The low power consumption of less than 2W allows for convenient power supply via USB2.0, enhancing portability.
