Attention:
(a) The definition of TX and RX for PIN3 and 4 differs from that of other sensors. |
|---|
(b) In batch 01 and subsequent batches, CAN_H is in PIN13 and CAN_L is in PIN14. RS485 is only in lot 00. |
(c) Cross-connect the PIN1-10 communication cable. Connect the RX of the North wake sensor to the TX of SSH-10, and connect the TX of the North wake sensor to the RX of SSH-10. TXRX here refers to the definition of SSH-10. |
(d) The ID in the table corresponds to the device ID of the North wake, which should be connected starting from 1 and increasing in sequence. |
3.1.1 Power Supply
Power Input Requirements: The voltage range should be 24VDC with a tolerance of ±5%, and the power supply capacity must be 0.4A or greater.
Ensure that abnormal power inputs, such as reverse polarity and overvoltage, are not allowed, as this may result in the concentrator becoming abnormal or damaged.
The power cable's diameter must meet the maximum current requirement of the power supply. It is recommended to use a diameter larger than 0.5 square mm.
Positive Terminal | Negative Terminal |
|---|---|
PIN26, 28 | PIN25, 27 |

3.1.2 Uplink Communication
RS485 Communication: Upload sensor data. By default, there is no terminal resistance. External 120 ohm resistance should be connected as required. To ensure communication quality, it is recommended to use the characteristic impedance of 120 ohms twisted pair cable or RS485 bus-specific cable. Table 2-3 provides definitions.
A | B | Shared Point |
|---|---|---|
PIN11 | PIN12 | Negative power supply PIN25,27 |
Table 3-3: Definitions of PORT RS485
CAN Communication: Upload sensor data. By default, there is no terminal resistance. External 120 ohm resistance should be connected as required. To ensure communication quality, it is recommended to use 120 ohm twisted pair cable or CAN bus dedicated cable. Table 2-4 provides definitions:
CAN_H (a) | CAN_L (a) | Common Ground |
|---|---|---|
PIN13 | PIN14 | Negative power supply connected to PIN25 and PIN27 |
Table 3-4: Definitions of RS485 PORT
(a) In batch 01 and later batches, PIN13 is labeled as CAN_H, while PIN14 is labeled as CAN_L. Only in batch 00 is it labeled as RS485.
3.1.3 Sensor
This code is used for communication with the North Wake Sensor TFmini Plus in a concentrator. The North Wake Sensor uses TTL UART communication and does not have a separate ID. The only way to differentiate between sensors is by their wiring position on the concentrator. Wiring starts at PIN1 and increases sequentially.
Positive 5V Power Supply | Negative Power Terminal GND | TX | RX | |
|---|---|---|---|---|
ID1 | PIN16 | PIN15 | PIN2 | PIN1 |
ID2 | PIN18 | PIN17 | PIN3(a) | PIN4(a) |
ID3 | PIN20 | PIN19 | PIN6 | PIN5 |
ID4 | PIN22 | PIN21 | PIN8 | PIN7 |
ID5 | PIN24 | PIN23 | PIN10 | PIN9 |

3.1.3 Connecting Cables
The PORT is a male pin connector. The corresponding female plug and pin types are as follows. Typically, there is one female plug and 28 pins:

This section provides an example of how to connect sensors and concentrators using ID1.
Definition of Concentrator | North Wake Sensor | |||
|---|---|---|---|---|
PIN1 | ID1_RX | <-> | TXD | PIN3 |
PIN2 | ID1_TX | <-> | RXD | PIN2 |
PIN15 | GND | <-> | GND | PIN4 |
PIN16 | ID1_5V | <-> | +5V | PIN1 |
Table 3-6: Reference Cable Connections for PORT Sensors
Note: To establish communication, cross-connect the communication lines. Connect the RX of North Wake Up to the TX of SSH-10, and connect the TX of North Wake Up to the RX of SSH-10. Connect the communication lines in sequence starting from 1, without skipping any. The attached North Wake Sensor TFmini Plus should follow the same line sequence: |

3.2 Ethernet (Optional)
The concentrator is equipped with one RJ45 Ethernet port that supports standard 100 Mbit/s, specifically 100BASE-TX. The RS485 port can also be used for upstream connections. We recommend using CAT5E or higher network cables.
This feature is optional.

5.1 Verify Power Supply to the North Awakens
Use your mobile phone camera to observe the transmitter surface of Beixing. If the power supply is functioning properly, the transmitter light can be observed through the camera.

VI. Frequently Asked Questions
Q: Some parts of the sensor have data, while others do not?
A: Firstly, check the connection and ensure that the connection definition is correct and the connection is secure. Abnormal connections may include short circuits, open circuits, virtual connections, cable harness shell damage, connector shell damage, and more. Next, consider replacing the sensor suspected of damage. If the fault is eliminated, it is likely that the sensor was damaged.
Q: SSH-10 The working indicator is blinking, but no message is being uploaded.
A: Make sure the connection is correct and use the serial port assistant to send AF BF 01 AA BB 02 D4 BF AF. If a return packet is received (with the same packet format as above), it indicates that the SSH-10 firmware is in query mode and needs to be rewritten.
