S130N-ISI Firmware Burning and Network Testing

The S130N-ISI is a fully integrated Power Line Communication (PLC) module based on the Unicomsemi VC6330 chip. It features a 32-bit ARM Cortex-M3 MCU, 32-bit DSP, embedded Flash, 1MB SRAM, and multiple communication interfaces. The module adopts an LCC package with an ultra-compact design, integrated line drivers, low power consumption, and strong noise immunity. It is widely applicable in smart streetlights, smart homes, central air conditioning, and other PLC real-time communication scenarios for ubiquitous power IoT edge devices. This document details the network testing process using QOGRISYS's innovative S130N-ISI module.

Pin Definitions

Notes:

1. For functional operations like AT commands or transparent data transmission, the Debug UART (TXD& RXD) is optional.
2. The APP service UART is configured as: Baud rate: 115200, Data bits: 8, Stop bits: 1, Parity: EVEN. Use sscom as the serial tool.
3. For Debug test, the APP service UART (TXD & RXD) is optional.
4. For firmware burning, connect the Debug UART.
5. Debug UART configuration: Baud rate: 921600, Data bits: 8, Stop bits: 1, Parity: NONE. Use TeraTerm as the serial tool.

Firmware Burning

1. Wiring for Firmware Burning

Connect L/N to 220V AC. Use a triple-wire cable to link the serial tool and the module’s Debug port:

TXD (tool) connect to RXD (module)

RXD (tool) connect to TXD (module)

GND (tool)connect to GND (module).

2. Open the ucmixProgramTool (provided by Unicomsemi). Burn the firmware via the Debug port with configuration below:

Baud rate: 921600

Parity: None.

2^nd box settings:

3^rd box settings:

Note: Both CCO and STA firmware are burned using the same method above.

Network Testing

Debug UART Network Test Wiring Diagram

1, Open TeraTerm (Debug port connected to PC).

Default settings:

baud rate: 921600,

data bits: 8,

stop bit :1,

parity:NONE.

Press Enter, If the CCO starts normally, it displays (1901.001);

Press Enter, STA shows (1901.000) under an unconnected condition.

2, On the CCO side check if STA is connected or not:

Use vc+pib=rt,4 to check connected STA count.

Use vc+pib=rt,3 to view network status.

3, On the STA side to check if it is connected or not:

Connect the STA’S Debug port and open TeraTerm as what shows above. Press Enter,it displays 1901.xxx , xxx means the assigned TEI after connecting.As the image shows below, TEI on the STA side should be the same as that assigned by the CCO end to the STA end.

4, Ping Test after the above steps, it indicates that the STA has successfully accessed the network.On the CCO, run vc+pinga=1 to start, then use vc+pinga=0 to stop test.

Use vc+pinga=s to view test results:

1^st red Box: Device ID.

2^nd red Box:STA’s TEI.

3^rd red Box: Success rate.

APP UART Network Test

Wiring diagram:

1. AT Mode:Use sscom (APP port connects to PC).

Default Settings: 

baud rate: 115200,

data bits: 8,

stop bit: 1,

parity: EVEN.

Enter AT+MODE=2\r\n (switch it to AT mode and press enter (response OK confirms normal startup).

On the CCO, use AT+TOPONUM\r\n to check STA connection counts.

After confirming all is correct, enter the AT command to test the relevant functions.

2. Transparent Mode:

Connect CCO and STA’s APP ports to PCs.

UART Default Settings: 

baud rate: 115200,

data bits: 8,

stop bit: 1,

parity: EVEN.

Confirm STA is connected, then use AT+MODE=0\r\n on both CCO and STA ends.Send data via CCO or STA serial port.
